Bones of the face and the skull

The skull is of a spheroidal figure, compressed on the sides, broader behind ihan before, and supported by its base on the vertebral column.

It is divided by anatomists into two parts, the cranium and the face ; the former being composed of eight bones, viz., the occipital, two 'parietal, the frontal, two temporal, the sphenoid, and the ethmoid ; the latter is made up of fourteen bones, viz., two superior maxillary, two malar, two ossa nasi, two ossa palati, two ossa unguis, two inferior turbinated bones, the vomer, and inferior maxilla ; the frontal bone is so situated as to be common to the cranium and face. The bones of the ear are not included in this enumeration, as they belong rather to a special organ than to the skeleton considered as the framework of the body.

The bones of the face are fourteen in number

The sphenoid bone (French: Sphénoïde) forms a large part of the base of the skull in the region of the anterior and middle fossae. It is very irregular in shape, and is best described as consisting of a body, two pairs of wings, and two pairs of processes.

These small bones are named " ungual" from a resemblance, if not in form, at least in thinness and size, to a finger-nail (unguis); they are also called the " lachrymal" bones, from their presenting each a groove, which, with a similar excavation in the nasal process of the superior maxilla, forms the lachrymal canal.

Each palate bone, (os palati,) wedged in between the superior maxillary and sphenoid bones, is common to the cavity of the mouth, nares, and orbit. In its form, this bone somewhat resembles that of the letter l, one part being horizontal, the other vertical.

There are two bones named malar, (os malse, malare, jugale, zygomaticum.) Each is common to the face and orbit, forming the most prominent point of the side of the former, and the greater part of the outer border of the latter. Its form is quadrangular.
