111. The Shoulder -Joint, Articulatio humeri, 



m section. 



The margin of the glcnoid cavity of the scapula is deepened by the 

 J.intltus cartilagineus. The fibrous and the synovial capsule lining it, bulge 

 outwards as in all articulations, at different places, corresponding to the 

 position of the bones which constitute the articulation. In the bicipital 

 groove, or rather canal, the tendon of the long head of the M. bleeps 

 runs ; the tendon is surrounded up to its origin at the highest point 

 of the I/tinljus cartilagineus by a duplicature of the synovial capsule ; 

 this sheath stretches down to the place of insertion of the J/~. pectoralis 

 major (Fig. 109).
