If your lab partner asked you to explain how the shape of the glenoid cavity and acetabulum impacts the mobility of the pectoral and pelvic girdles, which of the following would you most likely say?
A. Since the glenoid cavity is shallower than the acetabulum, the pectoral girdle has more mobility than the pelvic girdle.
B. Since the glenoid cavity is deeper than the acetabulum, the pectoral girdle has less mobility than the pelvic girdle.
C. Since the glenoid cavity is shallower than the acetabulum, the pectoral girdle has less mobility than the pelvic girdle.
D. Since the glenoid cavity is deeper than the acetabulum, the pectoral girdle has more mobility than the pelvic girdle.
