The hypoglossal nerve, also known as the twelfth cranial nerve, cranial nerve XII, or simply CN XII, is a cranial nerve that innervates all the extrinsic and intrinsic muscles of the tongue except for the palatoglossus, which is innervated by the vagus nerve.
7 lis 2022 · 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.
10 wrz 2024 · The hypoglossal nerve arises from the hypoglossal nucleus in the medulla oblongata of the brainstem. It then passes laterally across the posterior cranial fossa, within the subarachnoid space. The nerve exits the cranium via the hypoglossal canal of the occipital bone.
18 cze 2022 · The hypoglossal nerve is the twelfth cranial nerve (CN XII) (TA: nervus hypoglossus or nervus cranialis XII). It arises from the medulla and passes through the hypoglossal canal to the neck, where it travels to the sublingual space to supply somatic motor innervation to all of the intrinsic and extrinsic muscles of the tongue, with the ...
The hypoglossal nerve (CN XII) is a motor nerve that supplies general somatic efferent fibers to all intrinsic skeletal muscles of the tongue, three of the four extrinsic tongue muscles (except for the palatoglossus), and geniohyoid muscle, providing tongue movements, speech, and such function as swallowing.
