10 wrz 2024 · 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). In this article, we shall look at the anatomy of the hypoglossal nerve – its anatomical course, motor functions and clinical correlations.
20 maj 2024 · The hypoglossal nerve (CN XII) is exclusively a motor nerve carrying general somatic efferent fibers (GSE). It innervates all intrinsic and almost all extrinsic muscles of the tongue, as well as one suprahyoid muscle, the geniohyoid muscle.

7 lis 2022 · Introduction. The hypoglossal nerve is the 12th cranial nerve (CN XII). It is mainly an efferent nerve for the tongue musculature. The nerve originates from the medulla and travels caudally and dorsally to the tongue (see Image. The Hypoglossal Nerve). Go to: Structure and Function.
12 kwi 2019 · Cranial nerve XII is the hypoglossal nerve, a somatic motor nerve so named for its literal translation of “under” and “tongue.” In this article, we discuss the structure and function of the hypoglossal nerve, before describing the clinical relevance of this nerve. Check out our summary of the cranial nerves.
Function. Schematic image of the hypoglossal nerve and innervation targets. The hypoglossal nerve provides motor control of the extrinsic muscles of the tongue: genioglossus, hyoglossus, styloglossus, and the intrinsic muscles of the tongue. [2] .
