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.
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.
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.
3 lis 2023 · Hypoglossal nerve (CN XII) Cranial nerve 12 is a general somatic efferent nerve originating from the brainstem. It leaves the skull through the hypoglossal foramen. It’s function is to enable tongue movements.
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.
7 lis 2022 · The hypoglossal nerve consists of 4 branches: the meningeal, descending, thyrothyroid, and muscular. However, only the muscular branch is part of the real hypoglossal nerve originating from the nucleus. Other branches originate from spinal nerves (mainly C1/C2) or the cervical ganglia.
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 ...
