What does the pelvis do?
Transfers weight of the upper body to the lower body
Short notes on the composition of the pelvic girdle :
2 hip bones: huge and irregular and flatted

comparison of the female and male pubic arch (pubic angle/ arch)
Female: border angle(80-90)
Male: acute angle
Bone thickness of male and female pelvis
Female: less, lighter and thinner
Male: heavy, more bone thickness, more prominant
Comparison of pelvis of male and female:
female: true pelvis more wide and defines birth canal
male: true pelvis narrow
Notes on the femur
