The hyoglossus is a thin and quadrilateral extrinsic muscle of the tongue. It originates from the hyoid bone ; it inserts onto the side of the tongue. It is innervated by the hypoglossal nerve (cranial nerve XII) .
The hyoglossus, arises from the hyoid bone and retracts and depresses the tongue. The chondroglossus is often included with this muscle. The chondroglossus is often included with this muscle. The styloglossus arises from the styloid process of the temporal bone and draws the sides of the tongue up to create a trough for swallowing.
Ansa cervicalis. The superior root of the ansa cervicalis (formerly known as descendens hypoglossi [1]: 500 ) is by fibres of the cervical spinal nerve 1 [1]: 344 [3] (and, according to some sources, of cervical spinal nerve 2 as well [3]) that have joined and run with the hypoglossal nerve (CN XII) for some distance before [1]: 344 progressively [1]: 369 branching off the CN XII in the ...
The hypoglossal nerve provides motor control of the extrinsic muscles of the tongue: genioglossus, hyoglossus, styloglossus, and the intrinsic muscles of the tongue. [2] These represent all muscles of the tongue except the palatoglossus muscle, which is innervated by the vagus nerve. [2] The hypoglossal nerve is of a general somatic efferent ...
The inferior longitudinal muscle of the tongue is an intrinsic muscle of the tongue. [1] It is thin and oval in cross-section. It is situated between the paramedian septum, and the lateral septum. [2]
The body of the hyoid bone is the central part of the hyoid bone. [clarification needed]At the front, the body is convex and directed forward and upward. It is crossed in its upper half by a well-marked transverse ridge with a slight downward convexity, and in many cases a vertical median ridge divides it into two lateral halves.

The chondroglossus muscle is about 2 cm long. It arises from the medial side and base of the lesser horn of the hyoid bone. [1] It passes directly upward. [1] It then inserts by blending with the intrinsic muscles of the tongue, between the hyoglossus and genioglossus.
