In all the animals dissected, the hypoglossal nerve arose from the ventrolateral side of the medulla oblongata with two main roots and gave off a descending branch to the ansa cervicalis before reaching the division of the common carotid artery. Each of the twelfth pair of cranial nerves, supplying the muscles of the tongue. Origin: Its nucleus is located in the medulla conjunction. This is an uncommon site for the origin of isolated hypoglossal nerve palsy. The hypoglossal nerve fibers originate from the two hypoglossal nuclei and the nerve axons project their terminals to the ipsilateral part of the tongue (Barnard, 1940; Sax, 1969). This nerve arises from the hypoglossal nucleus of the dorsal medulla of the brain stem and traverses the hypoglossal canal in the basioccipital to supply the motor innervation to all of the intrinsic and all but one of the extrinsic muscles of the tongue. One structure that has been ne-glected in the search for anatomical evidence for the evolution of human vocal abilities is the hypoglossal nerve (cranial nerve XII). Purpose of study Confirmation of existence of afferent fibers and Origin: medulla oblongata and cervical spinal cord. Several French eponyms have been applied to clinical findings when three, four, or five (if the sympathetics are included) members of this group of nerves are involved. The hypoglossal nerve provides all motor functions for your tongue. We report a case of a large schwannoma of hypoglossal nerve origin in the upper neck in a 31-year-old male. -Runs along the lower jaw to the chin and the muscles below the lower lip. First appearance: before 1840. Axons of this nerve cross the lateral aspect of the olivary nucleus in the brain stem and emerge as numerous longitudinal small roots lateral to the pyramids. The primary afferent nerves originating from the trigeminal ganglion terminated in the subnucleus dorsalis (Vpd) of the principal nucleus (Vp), lateral margin of the caudal pars interpolaris (Vi), interstitial nucleus and laminae I and V of the pars caudalis (Vc). Though rare, the hypoglossal schwannoma should remain a consideration in the evaluation of a parapharyngeal space mass. In some species, such as swiftlets, there are no intrinsic syringeal muscles, meaning muscles having both their origin and insertion on the syrinx (Box 36, p. 275).

It innervates all the muscles of the tongue except palatoglossus muscle which is innervated by The motor nuclei Hypoglossal Nerve Schwannoma is a rare form of schwannoma that involves the cranial nerve XII (CN XII), or the hypoglossal nerve (HyN). Hypoglossal canal size has been used to date the origin of human-like speech capabilities to at least 400,000 years ago, and to assign modern human vocal abilities to *Neandertals. What does the hypoglossal nerve pass through? It is a nerve with a solely motor function. The nerve arises from the hypoglossal nucleus in the medulla as a number of small rootlets, passes through the hypoglossal canal and down through the neck, and eventually passes up again over the tongue muscles it supplies into the tongue. It then descends between the sternocleidomastoid muscle, which lies superiorly, and the external carotid artery, which lies deep to the nerve. The hypoglossal nerve is purely motor nerve, which innervates extrinsic tongue muscles and geniohyoid muscle. We will be discussing this nerves origin, course, and the structures supplied by the This branch was not seen on the right side of only one case. In this lecture Professor Zach Murphy will be teaching you about the hypoglossal nerve (cranial nerve XII). These roots merge at the small hypoglossal canal to form CN XII proper. Origin. Structures supplied by the hypoglossal nerve are indicated by solid lines, whereas those supplied by fibers of cervical origin are indicated by dashed lines. The paired nuclei extend almost The Hypoglossal Canal. Fibers arise from retina of eye and pass through optic canal of sphenoid bone. This nerve bundle only serves motor function. The tongue's extrinsic muscles help it move in different directions, while the intrinsic Some studies recommended that intraoperative neuromonitoring, particularly of the 10th and 12th cranial nerves, can be considered during surgery [ 30 ]. One structure that has been ne-glected in the search for anatomical evidence for the evolution of human vocal abilities is the hypoglossal nerve (cranial nerve XII). adverb.

The hypoglossal nerve provides all motor functions for your tongue. Ten of these pairs originate from the brainstem; two pairs originate from the cerebrum. The hypoglossal nuclei, exist as paired nuclei within the medulla oblongata that provide motor innervation to the intrinsic and extrinsic muscles of the tongue (excluding palatoglossus) via the preposition. It innervates all the extrinsic and intrinsic muscles of the tongue, except for the palatoglossus which is innervated by the vagus nerve. Its cells of origin are in the hypoglossal nuclei. For the patients that met the inclusion criteria for AHI, BMI and favorable pattern for palatal collapse about two-thirds met the study definition of success. In all the animals dissected, the hypoglossal nerve arose from the ventrolateral side of the medulla oblongata with two main roots and gave off a descending branch to the ansa cervicalis before This complex nerve network enables sensation and movement in the neck and trunk. A branch of the cervical plexus runs inside the sheath of the hypoglossal nerve, but the fibers of these two nerves don't join together in any way. extracranial hypoglossal schwannomas are extremely rare, and only few cases have been reported in literature till date [5].

The paired nuclei extend almost the entire length of the medulla just beneath the floor of the fourth ventricle, close to the midline, under the medial aspect of the hypoglossal In the open medulla, it is visible as what is known as the hypoglossal trigone, a The primary afferent nerves originating from the trigeminal ganglion terminated in the The muscular apparatus capable of acting on the syrinx to control vocalization receives input from the brain by the hypoglossal nerve. The nerve has a purely somatic motor function, innervating all the extrinsic and intrinsic muscles of the tongue (except the palatoglossus, innervated by vagus nerve). Origin of hypoglossal nerve. https://teachmeanatomy.info/head/cranial-nerves/hypoglossal The origin of fibers, in either case, remains the first and second cervical nerve. First recorded in 1840-50 . Descendens hypoglossi may be carried partly or completely by the vagus nerve instead of the hypoglossal nerve.. Schematic rendering of the skin incision ( a) and basic anatomy ( b) pertinent to hypoglossalfacial nerve anastomosis (HFA): the sternocleidomastoid muscle is displaced and the digastric muscle is visible. As ChAc is assumed to be exclusively an intraneuronal enzyme ( Kasa, 1971 ), it is a good marker for cholinergic neurons. The musculature it supplies develop as the hypoglossal cord from the 360-364 ISSN: 0340-2096 Subject: T he hypoglossal nerve (CN.
