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.
