fibula

[fib′yələ]
Etymology: L, buckle
one of the two bones of the lower leg, lateral to and smaller in diameter than the tibia. In proportion to its length, it is the most slender of the long bones and presents three borders and three surfaces for attaching various muscles, including the peronei longus and brevis and the soleus longus. Also called calf bone.

fibula

The slender bone on the outer side of the main bone of the lower leg (tibia). The fibula is fixed to the tibia by ligaments and helps to form the ankle joint, below, but plays little part in weight-bearing.

fibula

a bone present in the posterior limb of TETRAPODS lying slightly posterior to and parallel with the tibia. See PENTADACTYL LIMB.

fibula

(Latin clasp ) the smaller and outer of the two bones of the lower leg; articulates with the lateral condyle of the tibia at its upper end, and with the tibia and talus at its lower end. It is non-weight-bearing but assists in stabilizing the ankle. Figure 1.

fibula

most lateral of the two bones of lower leg: articulates proximally with inferior aspect of lateral condyle of tibia; distal end forms the lateral malleolus and articulates with lateral aspect of the trochlea of talus; linked throughout its length to lateral border of tibia by an interosseous ligament (see Table 1)

fibula

the lateral and smaller of the two bones of the hind shank. In the horse, ox and sheep, the shaft is vestigial or not present and the ends are fused with the tibia. In the pig, the bone is complete but the ends are free until several years of age when they fuse with the tibia. See also Table 10.
