Part 293

The term canal is somewhat misleading; it is rather a slit-like passage or space between the two oblique muscles, since the inguinal ligament is that part of the aponeurosis of the external oblique muscle which stretches between the external angle of the ilium and the prepubic tendon.

Footnote 54:

The obliquity of the tendon and the angle which it forms with the pelvic floor are of clinical importance in regard to manipulation of the fœtus in obstetrical cases. The slope varies in different subjects. In some cases the tendon forms about a right angle with the pubic bones.

Footnote 55:

The terms dorsal and ventral are here used in the topographic and not in the morphological sense. All the muscles of the group are ventral in the latter sense.

Footnote 56:

This is regarded as a vestige of the clavicle. On this basis the portion of the muscle from the vestige to the arm represents the clavicular part of the deltoid of man.

Footnote 57:

Günther states that this muscle assists in extension or flexion according to the position of the head of the humerus relative to the glenoid cavity.

Footnote 58:

M’Fadyean and Vaughan term this muscle the scapulo-ulnaris, while Arloing and Lesbre term it “Ancone accessoire du grand dorsal.” The above name seems to agree best with the chief insertion and action, although it certainly arises largely from the tendon of insertion of the latissimus dorsi.

Footnote 59:

This is considered to represent the part of the common extensor for the fourth and fifth digits.

Footnote 60:

Martin considers that this muscle represents the extensor indicis proprius and the part of the common extensor for the second digit.

Footnote 61:

In man the muscle is an extensor of the hand.

Footnote 62:

On account of the intimate union between the psoas major and iliacus they are frequently considered a single muscle, to which the name ilio-psoas is applied; some anatomists include the psoas minor also under this term.

Footnote 63:

By some anatomists the portion inserted into the crest is termed the gluteus accessorius, but Lesbre considers this the deep gluteus, homologous with the gluteus minimus of man. The portion inserted into the trochanteric ridge apparently represents the piriformis of man.

Footnote 64:

Apparently the muscle represents the biceps, together with part of the gluteus superficialis of man. Hence the names gluteo-biceps and paramero-biceps have been suggested.

Footnote 65:

This muscle was incorrectly designated the adductor magnus by Percivall and Strangeways. Its name, however, is not at all descriptive of its structure in the domesticated animals.

Footnote 66:

It has been customary to describe two adductors—a parvus or brevis, and a longus or magnus. This division is largely artificial, and has been abandoned in the new nomenclature—a return to the views of Bourgelat and Girard.

Footnote 67:
