The lower, or outer, portion of theartery lies close to the humerus, beneath the edge of the coraco-braehi-alis, resting upon the tendon of the latissimus dorsi, and covered bythe pectoralis major. The axillary vein, which is sometimes double,accompanies the artery, lying below it, and both artery and vein arein close relation with the nerve-trunks which traverse the axillaryspace. With the arm extended to a right angle, the course of theartery is nearly straight, and corresponds to an imaginary line whichis drawn from the junction of the inner and ini<ldle thirds of the clav-.

After the pectoralis major has been separated from its attach-ment to the clavicle and reflected downward, the pectoralis minor,together with the costo-coracoid membrane, will be exposed. Thecosto-coracoid membrane is a r,ather thickened sheath of fascia whichreaches from the inner border of the pectoralis minor upward, to beattached to the under surface of the clavicle and to the first rib; itis simply a reflection of the deep fascia which invests the pectoralis 708 UPPER EXTREMITY. minor, and s
