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). It acts to depress and retract the tongue.
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 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.
The inferior longitudinal muscle of tongue is an intrinsic muscle of the tongue. [1] It is situated on the under surface of the tongue between the genioglossus and hyoglossus. [citation needed] It is innervated by the hypoglossal nerve (cranial nerve XII). Its contraction shortens and thickens the tongue.
The dorsal lingual branches of lingual artery consist usually of two or three small branches which arise beneath the hyoglossus. They ascend medially to the back part of the dorsum of the tongue. [5] They supply the mucous membranes, the glossopalatine arch, the tonsil, soft palate, and epiglottis; anastomosing with the vessels of the opposite ...
The genioglossus is one of the paired extrinsic muscles of the tongue. It is a fan-shaped muscle that comprises the bulk of the body of the tongue. It arises from the mental spine of the mandible; it inserts onto the hyoid bone, and the bottom of the tongue. It is innervated by the hypoglossal nerve (cranial nerve XII). The genioglossus is the ...

It begins by numerous branches from the superficial surface of the gland, and runs forward between the mylohyoid, hyoglossus, and genioglossus muscles. It then passes between the sublingual gland and the genioglossus and opens by a narrow opening on the summit of a small papilla (the "sublingual caruncle") at the side of the frenulum of the tongue.
