Fig. 452.—Cross-section of Nasal Region of Horse. The section is cut about two inches (5 cm.) behind the nostrils and a little more than half an inch behind the labial commissure, a, Dorsal meatus; b, middle meatus; c, ventral meatus; d, diver- ticulum nasi; e, dorsal turbinate fold; /. ventral turbinate fold; ff, prominence caused by venous plexus which extends back on lower part of ventral turbinate; 1, nasal bone; 2, cartilage of septum nasi; 3, 4, palatine and nasal processes of palatine bones; 5, maxilla; 6, tendon of levator labii superioris proprius; 7, part of lateralis nasi muscle which goes to cartilage of ventral turbinate; S, S', levator nasolabialis; 9. dila- tor naris lateralis; 10, buccinator; 11, vomero-nasal organ; 12, naso- lacrimal duct (wide part); 13, lateral nasal artery; 14, 14', branches of superior labial artery; 15, palatine artery; 16, labial branches of infra- orbital nerve; 17, external nasal nerve; 18, hard palate; 19, cheek; 20, superior labial vein. The veins (black) are filled by a natural injec- tion. shaped somewhat like a com- ma, the convex margin being medial (Fig. 453). The cartil- ages are attached by fibrous tissue to the extremity of the septal cartilage. Each consists of an upper, quadrilateral curved plate, the lamina, and a narrow comu which curves ventro-laterally, supporting the medial wng and the inferior commissure, but not en- tering into the formation of the lateral wing. The lamina causes the projection of the upper part of the medial wing, from which the thick alar fold (Plica alaris) passes backward along the lateral wall of the nasal cavity to join the mucous fold which.
