Movements of the shoulder-joint are produced by nine muscleshaving that as their main function, along with one other (triceps)which acts on the shoulder-joint with one of its parts while itsmain action is upon the elbow-joint. The latter muscle will bedescribed in the next chapter; the nine are conveniently placed inthree groups of three muscles each. Three of the nine are largemuscles, placed above, in front, and at the rear; with each of thesegoes a small associate and a rotator of the humerus, as follows: Large muscles. Small associates.
