98 ANATOMICAL TECHNOLOGY. 



This forms a marked projection at the convexity of the shoulder, 

 a little ventro-cephalad of the acromion. 



Olecranon, Epicondylus and EpitrocMea — (Fig. 30, 46). — These 

 prominences about the elbow joint are recognized without difficulty 

 even in fat animals if the parts are manipulated between the thumb 

 and fingers. 



M. Mceps—{Fig. 74, 75). — The fusiform body of this muscle may 

 be felt on the ventral aspect of the antebrachium by rolling the soft 

 parts gently between the fingers upon the humerus. It is less dis- 

 tinct than in man, on account of the more distal extension of the 

 insertion lines of the pectoralis group of muscles. 



§ 232. Capitellum radii— Read of the radius. — By alternately 

 pronating and supinating the manus while a finger is pressed upon 

 the elbow a little ventro-distad of the epicondylus, the capitellum 

 may be felt during its rotation. 



Processus styloides ulncB et radii — The styloid processes of the 

 ulna and radius. — These are to be felt at the caudal and cephalic 

 sides of the wrist joint. 



Os pisiforme — (Fig. 30). — This forms a marked and somewhat 

 movable projection just proximad of the wrist, and on the caudo- 

 ventral border of the antebrachium. Just distad of it is a promi- 

 nent callosity — the Tiypothenar eminence (Fig. 105). 



§ 233. Trochanter — Trochanter major femoris — (Fig. 30). — This 

 projects considerably from the hip, a little ventrad of a line between 

 the Crista ilii and the Tuberositas ischii, and a little nearer the 

 latter. Its movement is distinct when the leg is moved. 



Patella — The knee pan. — When the crus is extended so as to 

 relax the muscles connected with the patella, this bone is easily 

 moved from side to side. 



Galcaneum. — This forms the marked projection on the ventral 

 aspect of the leg just proximad of the ankle ; it is sometimes called 

 the hock. 



Malleoli. — These processes of the distal ends of the tibia and 

 fibula are readily distinguished at the cephalic and caudal sides of 

 the ankle. 



ABDOMINAL TRANSECTION. 



§ 234. Since most of the dissections herein described involve 

 only the thorax, neck, head and arms, it is usually more convenient 

 and economical to divide the body into caudal and cephalic parts.
