The Tibia

Question

The tibia
A) articulates with the femur and the proximal and distal fibulae.
B) is part of the axial skeleton.
C) is the thin outer (lateral) bone of the leg.
D) articulates with the acetabulum.

Accepted Answer

The tibia articulates with the femur at the knee joint and with the proximal and distal fibulae at the ankle joint. It is the larger, weight-bearing bone of the leg, situated medial to the fibula. It is not part of the axial skeleton (which includes the skull, vertebral column, and rib cage), and it is not the thin outer bone of the leg (that is the fibula). The acetabulum is a socket in the hip bone and does not articulate with the tibia.
