The tibialis anterior is a long, slender muscle situated on the front of the shin. The tibialis anterior is also involved in inversion. It works together with the tibialis posterior, which is located deep beneath the calf muscles.

Origin

The tibialis anterior originates at the upper surface of the tibia (the major bone of the shin).

Insertion

It inserts on the underside of the medial cuneiform bone of the foot (almost in the middle of the foot).

Function

Ankle joint flexion (dorsi flexion) - raising the foot toward the shin.
