Q

Function of Pelvis

A

transmit the weight of the body from the vertebral column to the femurs;

to contain, support and protect the pelvic viscera;

to provide attachment for trunk and lower limb muscles.

Acetabular fossa

52
Q

(horseshoe-shaped)

is broadest superiorly where most of the body’s weight transmitted

it’s the ARTICULAR surface where the femoral head contacts,

its covered with articular cartilage and it is deficient inferiorly at the acetabular notch.

54
Q

is a ring of fibrocartilage that surrounds the circumference of the acetabulum.

A

55
Q

it’s the strongest and longest bone of the human
body, Its length is associated with a striding gait, its strength with weight and muscular forces
