Your X-ray exam reveals that you have fractured your fibula. Your physician remarks, "Well, it's better than breaking your tibia." Explain why a fracture of the tibia would be worse than a fracture of the fibula.
the fibula provides lateral support and stability for the fibula but it does not play a large role in weight bearing, as does the tibia

Pectoral:
-flexibility most important -lightweight -insecure axial and limb attachments
Pelvic:
-massive -secure axial and limb attachments -weight-bearing most important
opening in hip bone formed by the pubic and ischial rami
-obturator foramen -gluteal tuberosity
