Part 290

This is also called the subsphenoidal canal or pterygoid foramen.

Footnote 12:

On account of its deep situation, and the fact that it cannot be separated from its surroundings, the ethmoid must be studied by means of appropriate sagittal and transverse sections of the skull.

Footnote 13:

According to Martin, there are originally four centers, two anterior and two posterior (smaller) ones, which fuse in a variable manner.

Footnote 14:

This is commonly termed the styloid process. It is not the homologue of the styloid process of man.

Footnote 15:

This foramen is somewhat variable in position, but is commonly opposite the corner incisor. Smaller inconstant foramina are often present.

Footnote 16:

The alveolus for the temporary canine is commonly formed in the maxilla alone.

Footnote 17:

This bone is really a greatly developed first ethmoturbinal.

Footnote 18:

In the Stuttgart Nomenclator Anatomicus (S. N. A.) the body (Corpus) is the part which bears the teeth, and is divided into a pars incisiva and a pars molaris. The ramus is the rest of the bone.

Footnote 19:

These correspond to the great cornua of man.

Footnote 20:

This relation varies with age; in the young horse the third tooth, in the old subject the fourth, lies below the end of the crest.

Footnote 21:

This bone is probably equivalent to the fourth and fifth carpals of forms in which five carpal elements are present in the lower row.

Footnote 22:

It is also called the large pastern bone or os suffraginis.

Footnote 23:

This bone is also called the small pastern bone or os coronæ.

This bone is also called the os pedis or coffin bone.
