The lingual glands (Glandulse linguales) constitute a thick layer in the loose submucous tissue and also lie between the muscle bundles. Mucous glands are found also in part of the dorsum and sides of the tongue. The lingual muscles (Mm. linguse) may be divided into intrinsic and extrinsic.

The intrinsic musculature consists, not of distinct muscles, but rather of systems of fibers which run longitudinally, vertically, and transversely, blending with the extrinsic muscles, which are now to be described.'^.

Most of the left ramus of the mandible is removed. The concealed parts of the hyoid bone are indicated by dotted lines. 1. Stylo-glossus.—This is a long, thin muscle, which lies along the lateral part of the It arises by a thin tendon from the lateral surface of the great cornu of the hyoid bone, near the articulation with the small cornu. It terminates near the tip of the tongue by blending with its fellow of the opposite side and with the intrinsic musculature. The action is to retract the tongue. Unilateral con- traction would also draw the tongue toward the side of the muscle acting. \ .small muscular band sometimes arises on the thyroid cornu of the hyoid bone and ends on the tendon of origin of the sty!o-glossu3. In some cases a similar band arises higher uj), with and on the hy
