Transverse muscle of tongue
Intrinsic muscle of the tongue
From Wikipedia, the free encyclopedia
The transverse muscle of tongue (transversus linguae) is an intrinsic muscle of the tongue.[1] It consists of fibers which arise from the median fibrous septum. It passes laterally to insert into the submucous fibrous tissue at the sides of the tongue.[citation needed] It is innervated by the hypoglossal nerve (cranial nerve XII). Its contraction elongates and narrows the tongue.

Structure
The transverse muscle of the tongue is an intrinsic muscle of the tongue.[1] It consists of fibers which arise from the median fibrous septum. It passes laterally to insert into the submucous fibrous tissue at the sides of the tongue.[citation needed]
Innervation
The transverse lingual muscle is innervated by the hypoglossal nerve (CN XII).[2]
Function
Contraction of the transverse muscle of the tongue elongates and narrows the tongue.[3]
