The posterior or dorsal angle (Angulus caudalis) is thick and rough; it is 
opposite to the vertebral end of the seventh rib, and 
its position can be determined readily in the living 
animal. 
The glenoid or articular angle (Angulus glenoid- 
alis) is joined to the body of the bone by the neck 
of the scapula (Collum scapule). It is enlarged, 
especially in the sagittal direction. It bears the 
glenoid cavity (Cavitas glenoidalis) for articulation 
with the head of the humerus. The cavity is oval 
in outline, and its margin is cut into in front by the 
glenoid notch (Incisura glenoidalis), and is rounded 
off laterally; just above its postero-lateral part is a 
tubercle to which a tendon of the teres minor is at- 
tached. The tuber scapule! is the large rough 
prominence in front, to which the tendon of origin
