It ween the scapula ahovc and the lirected obliciuely downward and backward. This bone belongs to the class of long bones and con- sists of a shaft or Ijody and two extremities. The shaft is twisted in appearance and has four sur- faces. Tlic external surface is marked by the musculospiral groove. The internal surface is rounded from side to side and presents al)ove the middle the in- ternal tubercle, and in its lower third the medullary foramen. The anterior surface is flattened, wide above and narrow l^elow. The posterior surface is rounded and smooth. The external border is the only distinct one and shows a large prominence, named the deltoid tuberosity. The proxi- mal extremity is very large and somewhat four sided; it presents a head—an extremely convex articular surface for the glenoid cavity of the scapula. On each side of tlie head is a tuberosity; in front is a subdivided bicipital groove for the play of the tendon of the biceps muscle. A fossa is located between the head and the Incipital groove, in wdiich are numerous foramina. The distal extremity carries a pulley-like surface for the bones of the fore- arm ; the internal portion of this surface is larger than the exter- nal (distinguishingfeature). Im- mediately above and back of this articular surface is the deep olecranon Fig. 4.—Skeleton (lateral of left view). fore limb.
