| Definition:
The tibiofibula is the single bone of the lower leg of the frog. |
|
 Structure:
The tibiofibula is a long bone that articulates with the femur
above, and the tarsal bones, the calcaneus
and the astragalis bones below.
 Function:
In the resting position, contraction of the muscles
of the thigh inserted into the tibiofibula, causes it to straighten the
hinge joint of the knee, lifting the thigh
and lifting the leg, too. The muscles in the back of the tibiofibula, pull
the calcaneus and astragalis bones up at the
ankle, to gain more lift. (In humans, another bone, the talus, articulates
with the distal tibia and fibula, giving the flexibility of the ankle to
walk on slanted surfaces.)
