 Oi'igin : from the whole aiitei-ior surface of the scapula. Insertion : 

 by a round tendon to the proximal parts of the processus lateralis 

 humeri — in a position on the flexor surface of the humerus exactly 

 opposite that occupied by the insertion of the pars claviculo-plastro- 

 humeralis on the extensor surface.

 scapularis, 52 n. (see text), 53. Anconajus, 56. Humero-carj)ali-nietacar- 

 palis I., 59. Ulna-carpo-ulnaris, 60, 61. Ulna-carpo-radialis + carpali digiti 

 I.-V. dors., 63. Humero-carpali-ulnaris, 65. Huinero-digiti I.-V. volaris, 

 X ulna-carpalis, Y intrinsic hand-muscles. 



Fiirbringer mentions that in Chelone and Sjihargis these two 

 parts are more independent than usual, but states that both are 

 inserted upon the processus lateralis humeri. 



The two parts together form a very large mass of muscle.
