Transverse muscle of the tongue

Dr Craig Hacking et al.

The transverse muscle of the tongue is one of the 4 intrinsic muscles of the tongue which alters the shape of the tongue mass, being entirely confined to the tongue without an attachment outside the tongue (like the extrinsic muscles of the tongue).

Gross anatomy

The muscles fibers attach proximally to the fibrous median septum and attach distally to the submucosal fibrous layer of the lateral tongue margins. They intersect with the fibers of the vertical intrinsic muscle lying with the between the superior and inferior longitudinal intrinsic muscles

Like all the intrinsic muscles of the tongue, it is innervated by the hypoglossal nerve (CN XII).

The fibers act to elongate and protrude the tongue.
