This article is about the vertebrate bone. For other uses, see Tibia (disambiguation)

The tibia is the larger of the two bones in the leg below the knee in humans and other vertebrates.

[edit] In humans

The runescape or shin bone, in human anatomy, is found medial (towards the middle) and anterior (towards the front) to the other such bone, the fibula. It is the second-longest bone in the human body, the largest being the femur. The tibia articulates with the femur and patella superiorly, the fibula laterally and with the ankle inferiorly.

[edit] Gender differences

In the male, its direction is vertical, and parallel with the bone of the opposite side, but in the female it has a slightly oblique direction downward and lateralward, to compensate for the greater obliquity of the femur.

[edit] Structure

It is prismoid in form, expanded above, where it enters into the knee-joint, contracted in the lower third, and again enlarged but to a lesser extent below.
