Anterior Humeral Region. Coraco-brachialis,Biceps,Brachialis anticus. Dissection.—These muscles are ex-posed, on the removal of the integumentand fascia from the anterior half of theupper arm, and the clearing away ofthe areolar tissue. The CoRACO-BRACHiALTS, a namecomposed of its points of origin andinsertion, arises from the coracoidprocess in common with the shorthead of the biceps; and is insertedinto a rough line on the inner side ofthe middle of the humerus. Relations.—By its anterior surfacewith the deltoidand pectoralis major. Byits posterior surface with the shoulder-joint, the humerus, subscapularis, teresmajor, latissimus dorsi, short head ofthe triceps, and anterior circumflex vessels. By its internal borderwith the axillary and brachial vessels and nerves, particularly with the. * The muscles of tbe anterior aspect of the upper arm. 1. The coracoidprocess of the scapuhi. 2. The coraco-clavicular ligament (trapezoid), passingupwards to the scapular end of the clavicle. 3. The coraco-acromial ligament,passing outwards to the acromion. 4. The suhscapularis muscle. 5. Theteres major ; the triangular space above this muscle is that through whichthe dorsalis scapulse vessels pass. 6. The coraco-brachialis. 7. The The upper end of the radius. 9. The brachialis anticus ; a portion of themuscle is seen on the outer side of the tendon of the biceps. 10. The in-ternal head of the triceps. BICEPS. BRACHIALIS ANTICUS. 235 median and external cutaneous nerve, by tlie latter of wliicli it ispierced. By tlie external border witk the short head of the bicepsand brachialis anticus. The Biceps {his—KtcpaXal, two heads) arises by two tendons, one,the short head, from the coracoid process in common with the cora
