This joint, although so large, pos-sesses only one ligament, the capsular(fig. 352), but it receives the support ofa number of muscles which over itand are intimately connected with it. The shoulder-joint is capable of de-scribing a great variety and consider-able range of movement. It allows oftlexion, extension, abduction, adduction,rotation, and Fig. 352.—Capsiilar Ligament of Shoulder-Joint1, Scapula. 2, Humerus. 3, Capsular Ligament. HUMERO-RADIAL OR ELBOW-JOINT Three bones are engaged in the for-mation of this joint—the humerus above,the radius below, and the ulna lias two lateial ligaments passing fromthe humerus to the radius. The outerone is the stronger and shorter of thetwo; the inner, the longer and has also a capsular ligament of con-siderable extent, lined by synovial mem-brane. It is essentially hinge-like in itsaction, and admits only of movements of flexion and extension (fig. 353).
