The third set are (1) the posterior superior dental, usually two in number. They pass downward and outward through the pterygo-maxillary fissure into the zygomatic fossa where they give branches to the mucous mem- brane of the gums and the posterior part of the mouth. They then enter the posterior dental canals on the zygomatic surface of the superior maxillary bone to communicate with the middle dental nerve and branches to the lining mem- brane of the antrum of Highmore (superior maxillary sinus). It also gives off three branches to the molar teeth which enter the foramina at the apices of the fangs to supply the pulp. (b) The middle superior dental and the anterior superior dental are given off in the infraorbital sulcus. The middle supplies the bicuspid teeth and the mucous membrane of the antrum and the gums. After leaving the infraorbital nerve it passes downward and forward in a canal in the superior maxillary. These branches which supply the teeth anastomose with the anter- ior superior and posterior superior dental branches. At the junction of the middle and anterior is the ganglion of Bochdalek; at the junction of the middle and posterior is the ganglion of Valentin. PLATE OCX RECURRENT TO SYMPATHETIC- The Trochlear or Fourth Cranial Nerve. LESSON CXII. (c) The anterior superior branch is given off just before the infraorbital nerve enters the infraorbital foramen. It descends to supply the incisor and canine teeth. It gives branches to the gums and mucous membrane of the antrum and the nasal branch which enters the nasal fossa through a small foramen and supplies the mucous membrane of the forepart of the inferior meatus and its floor. It communicates with the nasal branch from Meckel's ganglion. The branches on the face are palpebral, labial, and nasal. The palpebral s
