78 THE SALAMANDER 



the muscle tends to draw the Hmb forwards and at the same time to 

 turn the humerus so as to depress the pre-axial side of the limb. If, 

 however, the foot is resting on the ground this tendency to twist the 

 humerus would assist in propelling the body forwards.

Tht caput longum (m.Q.hA.) IS a muscle of medium power covering the 

 posterior face of the humerus. It arises from the postero-lateral 

 border of the coracoid a little towards its dorsal side. Its fibres run 

 parallel with one another and with the humerus, and have a fleshy 

 insertion along the posterior surface of the distal half of this bone. 

 The caput breve is a short but powerful triangular muscle, separ- 

 ated from the former head by the N. brachialis. It arises from the 

 posterior third of the ventral surface of the coracoid, i.e. posterior 

 to the M. supracoracoideus, and also from the postero-lateral edge — 

 lateral to the head just described — and encroaches a little on the 

 dorsal and mesial sides of the coracoid. It is inserted on the posterior 

 face of the proximal half of the humerus, and immediately proximal 

 to the caput longum. 



Innervation: By the NN. coraco-brachiales from the R. super- 

 ficialis, N. brachialis. 



Function : Both heads serve to draw the arm caudalwards, or con- 

 versely, if the foot is resting on the ground to propel the body 

 forwards.
