Exploring the tibialis anterior muscle
The tibialis anterior muscle is one of several muscles that we’ll look at that move the foot and ankle. It’s part of what is referred to as the anterior compartment of the lower leg and it forms half of the anatomical stirrup. The other half is fibularis (peroneus) longus, and we’ll see it there again. This is the muscle that we associate with shin splints and the inflammation of the connective tissue as it is pulled off of the tibia.
What does the name of the tibialis anterior muscle mean?
Tibialis comes from the Latin word “tibia” which means “shinbone”. And, anterior comes from the Latin word “ante” which means “before.” So, tibialis anterior is the tibialis muscle which is located on the anterior side of the leg.
Where does the tibialis anterior muscle attach?
Tibialis anterior is located in the anterior compartment of the leg. Specifically, it originates on the lateral shaft and condyle of the tibia at the interosseous membrane.
It inserts on the medial cuneiform and the base of the first metatarsal.
What actions does the tibialis anterior muscle do?
Tibialis anterior is the strongest dorsiflexor of the ankle. And, it also creates inversion at the ankle joint.
