Two large tubercles ventrally mark the junction with the sphenoid. Proct'ssut! conius A^asal bone. Angle of mandible Mandible Mental foramen Fig. 129.—Skull of Ox; Lateral View. The jaws are separated for the sake of clearness. A, Parietal bone; B, squamous temporal bone; C, occipital bone; D, perpendicular part of palatine bone; E, maxilla; F, malar bone; G, lacrimal bone; H, premardlla; 1, occipital condyle; 2, paramastoid process; 3, meatus acusticus externus: 4, bulla ossea; 5, zygomatic process of temporal bone; 6. 6', zygomatic and temporal processes of malar bone; 7, supraorbital process; 8, orbital part of lacrimal bone; 9, lacrimal bulla; 10, fossa sacci lacrimalis; 11, facial tuberosity; 12, infraorbital foramen; 13, condyle of mandible; 14, coronoid process of mandible. The foramen lacerum is short and very narrow. In the adult animal the bone is excavated to contain an air-cavity which is regarded as a part of the frontal sinus. The sphenoid bone is short. The cerebral surface of the body presents a deep sella turcica, in front of which it rises abruptly. The high anterior part bears a central ridge, the ethmoidal spine, which joins the crista galli of the ethmoid. Two foramina occur on either side. Of these, the large anterior one is equivalent to the foramen rotundum, orbitale, and trochleare of the horse; it may be termed. Please note that these images are ex
