as to whether the illustration shows a male or female pelvis and provide two reasonsfor your decision.

Acetabula are close together; pubic anglelarch is lessthan 90"; narrow sacrum, heart-shapedpelvic inlet
11. Deduce why the pelvic bones of a fourJegged animal such as the cat or pig are much less massive than those of the human.
Thepelvicgirdle doesnot haveto carry theentireweightof thetrunkin thequadrupedanimal.
12. A person instinctively curls over his abdominal areain times of danger.Why?
Abdominal area orRansreceive the least
protectionfrom theskeletalsystem.
13. For what anatomical reasondo many women appearto be slightly knock-kneedl Thepelvisis broaderand theacetabula
and ilia are more laterally positioned. Thus, thefemur runs downward to the knee more obliquely than in the male
14. What doesfallen arches mean? A weakening,of the tendonsand lig,amentssupportinl the arches of the foot.
