The maxilla takes no part in the formation of the palatine canal. Sutural (or Wormian) bones are often present at its junction with the lacrimal and malar bones. The body of the premaxilla is thin and flattened, and has no alveoli, since the canine and upper incisor teeth are absent. A deep notch takes the place of the foramen incisivum. The nasal process is short, convex laterally, and does not reach to the nasal bone; the space between the two processes is greater than in the horse. The palatine process is narrow and is grooved on its nasal surface for the septal cartilage and the vomer. The palatine fissure is very wide. The palatine bone is very extensive. The horizontal part forms one-fourth or. Fig. 135.—Sagittal Section of Skull of Ox, without Mandible.
