The glossopharyngeal nerve (/ ˌ ɡ l ɒ s oʊ f ə ˈ r ɪ n (d) ʒ i ə l,-ˌ f ær ən ˈ dʒ iː ə l /), also known as the ninth cranial nerve, cranial nerve IX, or simply CN IX, is a cranial nerve that exits the brainstem from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve.Being a mixed nerve (sensorimotor), it carries afferent sensory and efferent . It enters the mouth between the medial pterygoid muscle and the ramus of the mandible and passes anteriorly under the oral mucosa medial to the third mandibular molar. The lingual vein passes medial to the hyoglossus, and the lingual artery passes deep to the hyoglossus. Citation, DOI and article data The hyoglossus muscle is a thin, quadrilaterally shaped muscle in the upper neck and the floor of the mouth. Posted on March 31, 2022 by March 31, 2022 by # Deep surface of hyoglossus is related to: (COMEDK-06) A. Hypoglossal nerve B. Glossopharyngeal nerve C. Lingual nerve D. Submandibular Ganglion. These represent all muscles of the tongue except the palatoglossus muscle. To measure the required parameters the anatomical landmarks taken were the posterior belly of digastric muscle (PBD), descendens hypoglossi of ansa cervicalis (AC), bifurcation of common carotid artery (CCA), tip of the mastoid process (TMP), lingual artery (LA) at the posterior border of hyoglossus muscle, tip of greater cornu of hyoid bone . This nucleus is about 2 cm. It's the 12th cranial nerve. It lies at first beneath the Pterygoideus externus, medial to and in front of the inferior alveolar nerve, and is occasionally joined to this nerve by a branch which may cross the internal maxillary artery. In 2 cases, 2 parallel submandibular ducts were found and the lingual nerve was crossing the upper duct from superior. The Lingual Nerve and What It Does. Crossed by lingual nerve, near the anterior border of hyoglossus. The submandibular ganglion suspended from the lingual nerve sits on it. The lingual artery is a direct branch of the external carotid artery; it takes off from the external carotid at the level of the greater horn of the hyoid bone[1]. The lingual artery then continues as the deep lingual artery running rostrally and ventrally along the lateral aspect of the genioglossus muscle and supplying dorsal lingual branches. Runs forward on the hyoglossus between lingual and hypoglossal nerves. See Page 1. lake zurich tornado 1967 function of hypoglossal nerve. It contains fibres from both the mandibular division of the trigeminal nerve (CN V 3) and from the facial nerve (CN VII). in length, and its upper part corresponds with the trigonum hypoglossi, or lower portion of the medial eminence of the . The hypoglossal nerve is the 12th cranial nerve. The lingual nerve (LN) is crossing the styloglossus muscle (SG) as it intermingles with the hyoglossus muscle (HG) at the side of the tongue. one of the paired extrinsic muscles of the tongue. The hyoglossus acts to both depress and retract the tongue. The hypoglossal nerve (CN XII) has two lateral, and terminal lingual branches. The lingual nerve continues anteroinferiorly to innervate the floor of the mouth and the submandibular gland. The function of each muscle/muscle group is as follows: Genioglossus- Draw the tongue forward from the root Hyoglossus- Retracts the tongue and depresses its side The hypoglossal nerve innervates all the intrinsic muscles and all but one of the extrinsic muscles (genioglossus, styloglossus, and hyoglossus) of the tongue. The descending lingual branches sup-plied the inferior part of the genioglossus, and the terminal . The lingual nerve is located deep and medial to the hyoglossus muscle and is associated with the submandibular ganglion. Additionally, the hypoglossal nerve (CN XII) and the lingual nerve pass over its external surface on their way to the tongue. It receives its motor innervation via the hypoglossal nerve. # Deep surface of hyoglossus is related to: (COMEDK-06) A. Hypoglossal nerve B. Glossopharyngeal nerve C. Lingual nerve D. Submandibular Ganglion. It is one of the extrinsic muscles of the tongue. 3, 4). The lingual nerve then passes anteriorly and medially, across the styloglossus muscle and lateral to the hyoglossus and genioglossus muscles, before coursing upward to divide into terminal branches that supply sensory innervation to the lingual mucosa . Additional images References The hypoglossal nerve, helping provide sensation to the hyoglossus as well as other muscles found in the tongue, is also known as the twelfth cranial nerve. The tongue is a highly mobile muscular organ consisting of a striated intrinsic lingual muscle proper and extrinsic muscles ( genioglossus, hyoglossus, and styloglossus) that anchor the tongue to the mandible and hyoid apparatus. After this, the lingual artery travels between the hyoglossus (superficial) and middle pharyngeal constrictor (deep) to supply blood to the tongue. Laterally, in between the hyoglossus muscle and the mylohyoid muscle lay several important structures (from superior in inferior): sublingual gland, submandibular duct, lingual nerve, vena comitans of hypoglossal nerve, and the hypoglossal nerve. Between the mylohyoid and hyoglossus ; Between sublingual gland and genioglossus muscle~ Lies on hyoglossus; Crossed laterally by the lingual nerve; Termination. These communications may distribute sensory fibres via the hypoglossal nerve [ 4 ], or may conduct proprioceptive fibres from muscles of the tongue to the lingual nerve for . bilateral to most but contralateral to . (B) Left . The hypoglossal nerve enables tongue movement. The hypoglossal nerve gives off this descending branch, then turns and runs forward. The lingual artery, the main artery that supplies the lingual muscles, passes between the hyoglossus and genioglossus. Submandibular duct (Wharton's duct) 5 cm long duct and runs forwards on hyoglossus, b/w lingual and hypoglossal nerves. It supplies motor function to the tongue and impairment causes problems with speech and eating. The extrinsic muscles consisted of some components, and the geniohyoid branch and the lingual branches arose on the hyoglossus. The prefix hypo is of Greek origin and means "under." Glossal, also from the Greek, mean "tongue." Anatomy the lingual nerve; located inferiorly to the deep process of the gland is the hypoglossal nerve; Submandibular (Wharton's) Duct extends from the anterior aspect of the submandibular gland deep to mylohyoid on the lateral surfaces of the hyoglossus muscle and genioglossus muscle, which are lateral to the hypoglossal nerve Lining epithelium of lung alveolus is A. simple columnar B. simple cuboidal C. simple squamous D. pseudo stratified ciliated columnar C.simple squamous. Continues forward between sublingual gland and genioglossus muscle. Deep part: Extension: Forward in the interval between the mylohyoid and hyoglossus up to the posterior end of the sublingual gland. The lingual nerve branches from the trigeminal nerve and provides part of the nerve supply to the tongue. Nerve communications were also found in the main body and near the apex of the tongue. Description. Lingual vasculature and retia mirabilia. nerve # 12. sensory/motor/both. The lingual nerve also communicates with branches of the hypoglossal nerve at the tip of the tongue, and at the anterior border of the hyoglossus by a loop of fibres . More distally, the lingual nerve started to communicate with the hypoglossal nerve before passing the anterior border of the hyoglossus muscle.

At the anterior border of the hyoglossus muscle crossed by lingual nerve which loops around it. The sphenomandibular ligament is a ﬂat, thin band descending from the sphenoidal spine and widening to reach the lingual of the mandibular foramen. Synonym(s): musculus hyoglossus [TA] , hyoglossal muscle, hyoglossus. It runs just below the styloglossus muscle, and passes forward into the gap between hyoglossus medially, and the mylohyoid muscle laterally: the same gap that the lingual nerve runs in. The submandibular duct and lingual vein course between the hyoglossus and mylohyoid muscles, and their positions can (G 8.28B;N 70;Gl 44.21B) Identify the lingual and hypoglossal nerves passing lateral to the hyoglossus muscle. Between the above named elements certain discrepancies and imprecisions can be observed in the literature concerning their relationship. The hyoglossus acts to both depress and retract the tongue. The inferior alveolar nerve also called as inferior dental nerve is a branch of the posterior division of the mandibular nerve.Before traversing the mandibular foramen, it first gives off the nerve to the mylohyoid, a motor nerve supplying the mylohyoid and the anterior belly of the digastric muscles.The lingual . Genioglossus Hyoglossus Styloglossus Stylohyoid Stylopharyngeus Cutting of the hypoglossal nerve in the hypoglossal canal would not interrupt the nerve supply to the: Hyoglossus muscle Structures that are medial/deep to the hyoglossus are the glossopharyngeal nerve(cranial nerve 9), the stylohyoid ligamentand the lingual arteryand lingual vein. Related above to lingual nerve, submandibular ganglion; and below to hypoglossal nerve. Muscles. Taste is a unique sense that arises from the chorda tympani nerve, which branches from the face nerve. The meningeal branch carries fibers from the sensory spinal ganglion of the spinal nerve C2. The lingual artery from the external carotid artery in the neck goes inside the tongue deep in the direction of the hyoglossus, among the hyoglossus and genioglossus. . The tongue is subdivided into an apex (the rostral free portion), a large body, and a relatively short root. These muscles are involved in moving and manipulating the tongue. 1 Its fibers arise from the cells of the hypoglossal nucleus, which is an upward prolongation of the base of the anterior column of gray substance of the medulla spinalis. The lingual nerve enters the tongue base from the parapharyngeal space just lateral to both the styloglossus and the hyoglossus muscles. The hypoglossal nerve is of a general somatic efferent (GSE) type.. The deeper structures include contents of floor of mouth and root of tongue. The submandibular duct (coloured green) originates from the deep part of the submandibular gland (SMG) on the surface of the hyoglossus muscle (HG). • Since the hypoglossal nerve innervates all tongue muscles, it obviously innervates the hyoglossus. Floor of the mouth on the sublingual papilla beside the frenulum of the tongue The hyoglossus muscle is a thin, quadrilaterally shaped muscle in the upper neck and the floor of the mouth. Innervation • Hyoglossus is innervated by the hypoglossal nerve. Once the inferior aspect of the compartment has been delimited, the next step is to identify the two major neural structures potentially acting as routes for tumor spread: the XII cranial nerve and the lingual nerve (LN). The lingual nerve is a branch of the mandibular nerve and provides the sensory innervation to the floor of the mouth. Hyoglossus: Comes up from the neck, depresses and retracts the tongue, .

The glossopharyngeal nerve (/ ˌ ɡ l ɒ s oʊ f ə ˈ r ɪ n (d) ʒ i ə l,-ˌ f ær ən ˈ dʒ iː ə l /), also known as the ninth cranial nerve, cranial nerve IX, or simply CN IX, is a cranial nerve that exits the brainstem from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve.Being a mixed nerve (sensorimotor), it carries afferent sensory and efferent . It enters the mouth between the medial pterygoid muscle and the ramus of the mandible and passes anteriorly under the oral mucosa medial to the third mandibular molar. The lingual vein passes medial to the hyoglossus, and the lingual artery passes deep to the hyoglossus. Citation, DOI and article data The hyoglossus muscle is a thin, quadrilaterally shaped muscle in the upper neck and the floor of the mouth. Posted on March 31, 2022 by March 31, 2022 by # Deep surface of hyoglossus is related to: (COMEDK-06) A. Hypoglossal nerve B. Glossopharyngeal nerve C. Lingual nerve D. Submandibular Ganglion. These represent all muscles of the tongue except the palatoglossus muscle. To measure the required parameters the anatomical landmarks taken were the posterior belly of digastric muscle (PBD), descendens hypoglossi of ansa cervicalis (AC), bifurcation of common carotid artery (CCA), tip of the mastoid process (TMP), lingual artery (LA) at the posterior border of hyoglossus muscle, tip of greater cornu of hyoid bone . This nucleus is about 2 cm. It's the 12th cranial nerve. It lies at first beneath the Pterygoideus externus, medial to and in front of the inferior alveolar nerve, and is occasionally joined to this nerve by a branch which may cross the internal maxillary artery. In 2 cases, 2 parallel submandibular ducts were found and the lingual nerve was crossing the upper duct from superior. The Lingual Nerve and What It Does. Crossed by lingual nerve, near the anterior border of hyoglossus. The submandibular ganglion suspended from the lingual nerve sits on it. The lingual artery is a direct branch of the external carotid artery; it takes off from the external carotid at the level of the greater horn of the hyoid bone[1]. The lingual artery then continues as the deep lingual artery running rostrally and ventrally along the lateral aspect of the genioglossus muscle and supplying dorsal lingual branches. Runs forward on the hyoglossus between lingual and hypoglossal nerves. See Page 1. lake zurich tornado 1967 function of hypoglossal nerve. It contains fibres from both the mandibular division of the trigeminal nerve (CN V 3) and from the facial nerve (CN VII). in length, and its upper part corresponds with the trigonum hypoglossi, or lower portion of the medial eminence of the . The hypoglossal nerve is the 12th cranial nerve. The lingual nerve (LN) is crossing the styloglossus muscle (SG) as it intermingles with the hyoglossus muscle (HG) at the side of the tongue. one of the paired extrinsic muscles of the tongue. The hyoglossus acts to both depress and retract the tongue. The hypoglossal nerve (CN XII) has two lateral, and terminal lingual branches. The lingual nerve continues anteroinferiorly to innervate the floor of the mouth and the submandibular gland. The function of each muscle/muscle group is as follows: Genioglossus- Draw the tongue forward from the root Hyoglossus- Retracts the tongue and depresses its side The hypoglossal nerve innervates all the intrinsic muscles and all but one of the extrinsic muscles (genioglossus, styloglossus, and hyoglossus) of the tongue. The descending lingual branches sup-plied the inferior part of the genioglossus, and the terminal . The lingual nerve is located deep and medial to the hyoglossus muscle and is associated with the submandibular ganglion. Additionally, the hypoglossal nerve (CN XII) and the lingual nerve pass over its external surface on their way to the tongue. It receives its motor innervation via the hypoglossal nerve. # Deep surface of hyoglossus is related to: (COMEDK-06) A. Hypoglossal nerve B. Glossopharyngeal nerve C. Lingual nerve D. Submandibular Ganglion. It is one of the extrinsic muscles of the tongue. 3, 4). The lingual nerve then passes anteriorly and medially, across the styloglossus muscle and lateral to the hyoglossus and genioglossus muscles, before coursing upward to divide into terminal branches that supply sensory innervation to the lingual mucosa . Additional images References The hypoglossal nerve, helping provide sensation to the hyoglossus as well as other muscles found in the tongue, is also known as the twelfth cranial nerve. The tongue is a highly mobile muscular organ consisting of a striated intrinsic lingual muscle proper and extrinsic muscles ( genioglossus, hyoglossus, and styloglossus) that anchor the tongue to the mandible and hyoid apparatus. After this, the lingual artery travels between the hyoglossus (superficial) and middle pharyngeal constrictor (deep) to supply blood to the tongue. Laterally, in between the hyoglossus muscle and the mylohyoid muscle lay several important structures (from superior in inferior): sublingual gland, submandibular duct, lingual nerve, vena comitans of hypoglossal nerve, and the hypoglossal nerve. Between the mylohyoid and hyoglossus ; Between sublingual gland and genioglossus muscle~ Lies on hyoglossus; Crossed laterally by the lingual nerve; Termination. These communications may distribute sensory fibres via the hypoglossal nerve [ 4 ], or may conduct proprioceptive fibres from muscles of the tongue to the lingual nerve for . bilateral to most but contralateral to . (B) Left . The hypoglossal nerve enables tongue movement. The hypoglossal nerve gives off this descending branch, then turns and runs forward. The lingual artery, the main artery that supplies the lingual muscles, passes between the hyoglossus and genioglossus. Submandibular duct (Wharton's duct) 5 cm long duct and runs forwards on hyoglossus, b/w lingual and hypoglossal nerves. It supplies motor function to the tongue and impairment causes problems with speech and eating. The extrinsic muscles consisted of some components, and the geniohyoid branch and the lingual branches arose on the hyoglossus. The prefix hypo is of Greek origin and means "under." Glossal, also from the Greek, mean "tongue." Anatomy the lingual nerve; located inferiorly to the deep process of the gland is the hypoglossal nerve; Submandibular (Wharton's) Duct extends from the anterior aspect of the submandibular gland deep to mylohyoid on the lateral surfaces of the hyoglossus muscle and genioglossus muscle, which are lateral to the hypoglossal nerve Lining epithelium of lung alveolus is A. simple columnar B. simple cuboidal C. simple squamous D. pseudo stratified ciliated columnar C.simple squamous. Continues forward between sublingual gland and genioglossus muscle. Deep part: Extension: Forward in the interval between the mylohyoid and hyoglossus up to the posterior end of the sublingual gland. The lingual nerve branches from the trigeminal nerve and provides part of the nerve supply to the tongue. Nerve communications were also found in the main body and near the apex of the tongue. Description. Lingual vasculature and retia mirabilia. nerve # 12. sensory/motor/both. The lingual nerve also communicates with branches of the hypoglossal nerve at the tip of the tongue, and at the anterior border of the hyoglossus by a loop of fibres .

Related above to lingual nerve, submandibular ganglion; and below to hypoglossal nerve. Muscles. Taste is a unique sense that arises from the chorda tympani nerve, which branches from the face nerve. The meningeal branch carries fibers from the sensory spinal ganglion of the spinal nerve C2. The lingual artery from the external carotid artery in the neck goes inside the tongue deep in the direction of the hyoglossus, among the hyoglossus and genioglossus. . The tongue is subdivided into an apex (the rostral free portion), a large body, and a relatively short root. These muscles are involved in moving and manipulating the tongue. 1 Its fibers arise from the cells of the hypoglossal nucleus, which is an upward prolongation of the base of the anterior column of gray substance of the medulla spinalis. The lingual nerve enters the tongue base from the parapharyngeal space just lateral to both the styloglossus and the hyoglossus muscles. The hypoglossal nerve is of a general somatic efferent (GSE) type.. The deeper structures include contents of floor of mouth and root of tongue. The submandibular duct (coloured green) originates from the deep part of the submandibular gland (SMG) on the surface of the hyoglossus muscle (HG). • Since the hypoglossal nerve innervates all tongue muscles, it obviously innervates the hyoglossus. Floor of the mouth on the sublingual papilla beside the frenulum of the tongue The hyoglossus muscle is a thin, quadrilaterally shaped muscle in the upper neck and the floor of the mouth. Innervation • Hyoglossus is innervated by the hypoglossal nerve. Once the inferior aspect of the compartment has been delimited, the next step is to identify the two major neural structures potentially acting as routes for tumor spread: the XII cranial nerve and the lingual nerve (LN).
