    are united a little below the middle of the fore part of the os humeri, and form a muscle of which the outline is distinct when covered by the integuments. Insertion. By a strong roundish tendon into the inner side of the tubercle of the radius. Along the inner side of this muscle are passing the principal vessels of the extremity. These are placed on the anterior part of the arm, to the inner side of the biceps muscle, as far as the bend of the elbow: at this part a division takes place, and during the greater part of the rest of their course, they become situated on either side of the fore-arm, in the region of the radius and ulna. A considerable bursa is situated betw-een the lower tendon of this muscle and the tubercle of the radius. 3. Brachialis Internets. Covers the anterior and inner surface of the under half of the os humeri. Origin. Fleshy, from about the middle of the os humeri by two attachments, which extend above the insertion of the deltoid muscle on each side. It forms a strong muscle, which passes over the fore part of the capsule of the elbow joint, to which it firmly adheres. Insertion. By a strong short tendon into the coronoid pro- cess of the ulna. A bursa is sometimes found between the tendon of this muscle, that of the biceps and capsule of the joint. b. Posterior Brachial, containing the 1. Triceps Extensor Cubiti. Covers the whole of the back part of the os humeri, and reaches from the scapula to the elbow. Origin. By three heads. The long head(caput longum) arises by a short thick tendon, from the inferior costa of the scapula, immediately before the attachment of the teres minor. The short head (caput breve) arises by an acute tendinous and fleshy beginning from the outer and back part of the os humeri just below the head. The third head is called the brachialis externus: it arises by an acute beginning from the back part of the os hu- meri, near the insertion of the teres major. The three heads unite about the middle of the humerus, but continue to adhere to the whole of the posterior surface of the bone, and to the condyles. Insertion. By a broad thick and strong tendon into the upper and outer part of the olecranon of the ulna. Between this tendon and the olecranon is situated a considerable bursa; and sometimes one or two smaller ones.
