Under this name is described a thin band, formed of parallel fibres, which is exposed immediately on remov- ing the mucous membrane, with the subjacent glands, from the base of the tongue. This band arises from the inner side of the articulation uniting the body of the os hyoides to its small branch. It passes above the trans- verse muscle of that bone, which it crosses perpendi- cularly, is surrounded at this point by a great mass of adipose tissue, and is prolonged directly forward, be- neath the lingual mucous membrane. Its fibres then vanish, either on the superior aspect of the tongue or on its sides, or they descend obliquely in crossing the direction of the hyo-glossus, to join the superior border of the stylo-glossus (Fig. 149, 3). (This muscle contracts and retracts the tongue.) PHARYXGO-GLOSSUS. {Synonym.— palato-glossus of Man.) A rudimentary muscle formed of parallel fibres, which, from their origin on the lateral wall of the pharynx, pass outside the articular angle of the branches of the OS hyoides, and between the hyo-glossus and genio- glossus, mixing with, and intercrossing their fibres. 3. Labial glands.—The numerous glands of the tongue may be divided into racemose (or lobulated) glands, and closed follicles (or follicular glands.) The racemose glands are spread on the sides and base of the tongue. Near its upper border they form two rows, which are rendered visible by the presence of a small tubercle placed beside each of them. At the base of the tongue they are found beneath the fungiform and calyciform papillse, as well as beneath the layer of inclosed follicles which lines the isthmus of the fauces. At the entrance to this passage, the lingual mucous membrane is mammillated, and each elevation has an OKE LOBE OF A RACE- MOSE GLAND. 1, Casing of connective tissue; 2, Excretory du
