ANATOMICAL TECHNOLOGY. 



Entopectoralis t do. caudalis ( 656). The right humeral portion is hidden. The left 

 was separable into two divisions. 



Entopectoralis, do. cephalica ( 658). On the right little of this is visible. On the left 

 it is almost wholly exposed. 



Epitrochlearis ( 681). The left is entire, passing from the latissimus to the elbow, 

 where it is associated with the pecto-antebrachialis. On the right side is seen the reflected 

 distal half. 



FIG. 72. THE PECTOBALIS GROUP OP MUSCLES, PARTLY DISSECTED. 



Latissimus ( 635). A fragment of the right is visible. The left has the appearance 

 of passing ectad of the Uceps ; in reality, however, most of it passes entad of the biceps, 

 and what appears to be the continuation of the latissimus is the tendon of the xiphi-hume- 

 ralis which passes entad of the caudal division of the entopectoralis. 



Pecto-antebrachialis, dv. cephalica ( 646), dv. caudalis ( 647). These are shown entire 

 on the right, but on the left they have been removed excepting the distal ends. 



Sterno-mastoideus ( 622). The sternal ends of both are shown, including the mesal 

 raphe formed by the interdigitation of their fibers. 



Supinator longus ( 690). Part of this appears on the right. 



Supraspinatus ( 675). This is more fully shown in Fig. 73, 74.
