The hard palatepresents four sutures: (1) median, (2) premaxillary-maxillarj(poorly marked in Hie adult), (3) maxillary-palatine, and ( I)palatine-sphenoid. The foramina of the hard palate are: (1)anterior palatine, at the point where the preinaxillarY-niaxillarv (409) 410 HUMAN ANATOMY. suture crosses the median, subdivided into four openings, (2)two posterior palatine, and (3) twg. accessory. These last fourforamina transmit the posterior descending palatine nerves andvessels. The alveolar process for the implantation of the teeth is aridge of bone superimposed peripherally, in the upper jaw, uponthe premaxillary and maxillary bones. When fully functioningit is not demarcated from these bones, but before the teeth comeand after they go it does not exist. Its body is spongy. Its cor-tex is dense, and surrounding each tooth root-socket it is some-what condensed (lamina dura, of some significance radiographic-ally for the prognosis of pyorrhea alveolaris). In cross-section. Fig. 147. Sutures of the hard palate, a, premaxillary bone;maxillary bone; c, palatine bone. it is somewhat U-shaped. It has two free surfaces, the internaland external alveolar plates. Of these the external is much thethinner, which fact is taken advantage of in extraction. The mandible (Fig. 148) exhibits an alveolar process essen-tially similar to that of the maxillary. In cross-section themandible is U-shaped. The cortex is dense, the interior cancel-lated. Within its body runs the inferior dental nerve and blood-vessels inclosed in a cribriform tube in close proximity to theroots of the teeth. In most cases the mental canal points for-ward into the body of the bone, and hence it is a recurrent
