The sublingual gland of the left side has been laid bare by- removing the mucous membrane ; to expose the anterior lingual gland of the right side a thin layer of muscle, in addition to the mucous membrane, has been removed. A branch of the lingual nerve is seen running on the medial aspect of the gland. The rauine vein is faintly indicated on this side also (from Birmingham). The pair of mucous glands situ- ated on the inferior surface of the tongue a little behind its tip, and known as the anterior lingual glands, are of interest in that they occasion- ally give rise to mucous cysts similar to those which develop in connexion with the labial glands (Fig. 1084). The muscular bundles of the tongue are separated by a quantity of loose connective tissue, rich in blood- and lymph vessels (Fig. 1083); hence acute inflammatory oedema of the substance of the tongue may be attended with a degree of swelling sufficient to ob- struct the respiratory passage.
