The Muscles loi 



des Armes, Obergratenmuskel, Hebemuskel des 

 Oberarmes, Epicoraco-humeralis) . A muscle of 

 considerable size at the anterior region of the 

 coracoid and the under region of the scapula, 

 which is divided into two parts : (a) the coracoid 

 (inferior) division is the stronger and arises from 

 the whole anterior half of the coracoid, from its 

 outer and inner surfaces; it is inserted, together 

 with the second part, on the proximal, little- 

 developed part of the processus lateralis humeri; 

 (b) the scapularis (superior) division is the weaker 

 of the two and is covered by the deltoides scapu- 

 laris inferior muscle; it arises from the surface 

 of the under third of the scapula, behind the spine ; 

 it unites with the preceding part to form a single 

 muscle and inserts itself, as said above, on the 

 proximal part of the processus lateralis humeri. 



Coraco-brachialis (Brevis) (Plate I., Figs. 4, 5, 

 and 6, ebb) (Theil des grossen Brustmuskels oder 

 Hakenarmmuskel, Pectoralis IL, Pectoralis minor) . 

 A fairly strong muscle. It arises from the outer 

 surface of the coracoid, except the median edge 

 and the anterior section, and runs to the flexor 

 surface of the upper arm where it is inserted on 

 the proximal third between the lateral and median 

 processes.
