Osteology Bones

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.

The scapula (French : scapula, omoplate), is placed upon the upper and back part of the thorax, occupies the space from the second to the seventh rib, and forms the posterior part of the shoulder. Its form is irregularly triangular and flat. It presents for examination two surfaces, three borders, and three angles.

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.

The ulna, (French : ulnlna) is placed at the inner side of the forearm ; it is a long and rather irregular bone, larger at the upper than at the lower extremity, a conformation the reverse of that which obtains in the radius.

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.

The radius (French : Radius), shorter than the ulna by the length of the olecranon process, is placed at the external side of the fore-arm, extending from the humerus to the carpus. It is broader below than above, slightly curved in its form, and divided into a body and two extremities.

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.

The clavicle (French : la clavicule) is placed laterally at the anterior and upper part of the thorax, it completes ahead the thoracic belt, to which the member of the same name is attached.
