It is oblique downwards and backwards, pyriform, enlarged at its superior extremity, contracted inferiorly, where it terminates by two small flat tendons. Attachments.—It originates, by its superior extremity, from the inner aspect of the humerus, behind and above the tuberosity on its body. One of its terminal tendons is attached to the summit of the olecranon ; the other glides over a small convexity on the inner side of that eminence, and goes to be inserted a little lower
. The comparative anatomy of the domesticated animals. Veterinary anatomy. MUSCLES OF THE ANTERIOR LIMBS. S21 ^ig. 182. It is oblique downwards and backwards, pyriform, enlarged at its superior extremity, contracted inferiorly, where it terminates by two small flat tendons. Attachments.—It originates, by its superior extremity, from the inner aspect of the humerus, behind and above the tuberosity on its body. One of its terminal tendons is attached to the summit of the olecranon ; the other glides over a small convexity on the inner side of that eminence, and goes to be inserted a little lower than the first. Relations.—Above, with the inferior border of the large extensor ; outwards, with the humerus, the short flexor, and short extensor of the forearm ; in- wards, with the humeral insertion of the latissimus dorsi and the abductor of the arm, the long branch of the flexor brachii, the vessels and nerves on the inner side of the arm, and the long extensor of the forearm. Action.—An extensor of the forearm. 4. Small Extensor of the Fokearm or Anconeus (Fig. 128, 10). Synonym.—Humero-olecranius minor—Girard. Form—Structure—Situation—Relations.—This is a small, thick, and prismatic muscle, almost entirely fleshy, situated behind the elbow articulation. It is applied against the synovial cul-de-sac which ascends into the olecranian fossa, and to which it is strongly attached ; it is hidden by the short extensor, from which it is not easily distinguished. Attachments.—It originates from the margin of the olecranian fossa, chiefly above and outwards. It terminates by being inserted into the anterior and external part of the olecranon. Action.—This little muscle, a congener of the preceding, raises the articular capsule it covers, and prevents its being pinched between the bony surfaces. Differential Characters in the Muscles of the Arm IN THE other Animals. In all animals, the long flexor of the forearm, or flexor brachii, is less thick and tendinou
