The tibialis anterior inserts on which part of the foot?

Explanation:
The action of a muscle comes from where its tendon attaches. Tibialis anterior attaches to the medial cuneiform and the base of the first metatarsal, on the dorsum of the foot. This placement lets it pull the great toe side of the foot upward and inward, producing dorsiflexion (lifting the foot) and inversion (turning it inward). The other options don’t reflect tibialis anterior’s insertion: the calcaneus is tied to the Achilles tendon, the navicular and cuboid are associated with other tendons, and the lateral malleolus is a bone landmark rather than an insertion site.
