Its origin is pierced by the circumflex scapular artery. The muscle is invested by the deep fascia enclosing the infraspinatus, and is sometimes inseparable from that muscle. Nerve-Supply.—The teres minor is supplied by a branch of the axillary nerve (C. 5. 6.). The nerve has a pseudo- ganglion, a fibrous swelling on it in its course to the muscle, Action.—The muscle is a lateral rotator of the humerus. M. Teres Major.—The teres major is much larger than the preceding muscle. It arises by fleshy fibres from the lower third of the flat surface on the dorsum of the scapula along its axillary ,^puue.
