    scapula. The fibres converge as they descend and form strong bundles, which are intermixed with tendon. Insertion. Tendinous below the pectorahs major, into a rough eminence on the outer side of the os humeri, near its middle. Under the upper part of this muscle, between it and the cap- sule of the shoulder-joint, is a considerable bursa mucosa, which commonly extends forward under the acromion. It is sometimes double. b. Posterior Scapular, containing the 1. Supra-spinatus. Occupies the fossa supra- spinata. Origin. Fleshy from the whole of the fossa supra-spinata, from the upper part of the spine, from that part of the base which is above the spine, and from the superior costa of the scapula. It passes under the acromion, forms a strong tendon, which passes over the capsule of the joint, and thereby strength- ens it. Insertion. Into the upper and inner part of the larger tu- bercle of the os humeri. 2. Infra-Spinatus. Is of a triangular figure, and occupies the fossa infra-spinata. This, and the above de- scribed muscle, are covered by a strong aponeurosis, to which many of their fleshy fibres are attached. Origin. Fleshy, from the dorsum below the spine, from the under surface of the spine, and from that part of the base of the scapula which is below the spine. The fibres pass obliquely towards a middle tendon, which passes fonvard, and adheres to the capsular ligament. Insertion. By the above thick and short tendon into the middle part of the larger protuberance on the head of the os humeri. Under the tendon of this inusifie, between it and the scapula, is a considerable bursa mucosa. S. Teres Minor. Is a small oblong muscle, which lies under, and is often not distinctly separated from the former. Origin. Fleshy from the middle, and rounded part of the inferior costa of the scapula. It runs forward under the infra-spi- natus, and adheres to the capsular ligament. Insertion. By a strong short tendon into the under and back part of the greater protuberance on the head of the os humeri.
