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.
