Excerpt: ...the back of the elbow-joint, to be inserted into the whole of the superior surface of the olecranon; but some are continuous with the other part of the muscle, or anconeus proper, passing for this purpose through the deep notch between the ectocondyle and the outer angle of the olecranon. The superficial portion of the muscle, however, has pretty distinct origin from the ectocondyle, and thence spreads out fan-shaped, to be inserted fleshy into the whole outer and back surface of the ulna as far along as the origin of the abductor pollicis longus (except just along the edge and at the tip of the bone, which are reserved for origin of extensor carpi ulnaris). The attachments and oblique traction of this muscle make it a powerful rotator of the forearm upon the humerus, as well as an extensor. It is opposed by Antanconceus.--A muscle of considerable size that lies very obliquely across the inner side of the back of the elbow. It arises from the tip of the entocondyle in connection with the pronator and carpal "flexors," and immediately forms a thick, bulging fleshy belly that rather suddenly contracts to a short, stout, rounded tendon to be definitely inserted into the prominent tubercle at the inner corner of the olecranon. The muscle lies mostly upon the expanded inner condyle and fills up what would otherwise be an hiatus between the inner head of the triceps below and the ulnar head of the "flexor" carpi ulnaris. It subserves the rotary motion of the forearm, as well as extends the latter; producing a movement corresponding to supination, and thus directly counteracting the foregoing. Brachialis anticus.--(Flexor cubiti ulnaris.) Returning now to the flexor set, we find that the "short" or humero-ulnar...
