The coraco-brachialis muscle (French: muscle coraco-brachial) - named from its attachment to the coracoid process and he upper arm braclhium - is a cylindrical muscle, but somewhat fusiform at the extremities.
The sphenoid 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 vomer (Fench: le Vomer) is an irregular four-sided plate of bone constituting the lower portion of the nasal septum. It is usually described as resembling a ploughshare in shape. Each lateral surface is covered with the thick mucous membrane of the nasal sinus, and is traversed by a narrow but well-marked groove, which lodges the naso- palatine nerve from the spheno-palatine ganglion; hence it is sometimes called the naso-palatine groove.
The spine (vertebral column) consists of thirty-three superimposed bones termed vertebrae. Of these the upper twenty-four remain separate throughout life and form three groups. The first seven are called cervical, the succeeding twelve thoracic (dorsal), and the last five lumbar. In adult life the last nine vertebras ankylose to form two composite bones named the sacrum and the coccyx. The sacrum is formed by the fusion of five vertebrae from the twenty-fifth to the twenty-ninth inclusive; the four terminal are vestigial, and form the coccyx. In order to gain a general notion of the characters of a vertebra, it is desirable to select a bone from the middle of the thoracic series.
We have seen, that after bringing together all the fragments the Hippocratic writers have transmitted to us, relative to the structure of the human body, it would be impossible to compose from them a regular or complete treatise on anatomy ; for, with the exception of the skeleton, they possessed very limited and imperfect notions of any organic apparatus. They confounded, under a common name, the
