THE LIMBS OF THE HOKSE

Just as the insertion of the subscapular muscle may be regarded 

 as functioning as a medial collateral ligament, so may the strong 

 tendinous insertion of the infraspinous muscle be regarded as render- 

 ing the presence of a lateral collateral ligament unnecessary.

the shoulder joint, between the triceps and the deltoid and infraspinous 

 muscles. To see the origin of the muscle it is necessary to remove a 

 part of the infraspinous. 



The teres minor has a tendinous origin from the greater part of the 

 axillary border of the scapula and an oblique line in the distal part of 

 the infraspinous fossa, and a fleshy origin from a tubercle close to the 

 margin of the glenoid cavity. The insertion is to the proximal part of 

 the crest of the greater tubercle of the humerus.
