The Muscles 101 
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, cbb) (Theil des grossen Brustmuskels oder 
Hakenarmmuskel, Pectoralis II., 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.
