The tibialis anterior muscle is a major anterior leg muscle whose main action is dorsiflexion and inversion of the foot (i.e., “toes to nose” and turning foot inward.)
The proximal attachment (origin) of the muscle is the tibia. The distal attachment (insertion) of the muscle is the medial cuneiform bone of the ankle and also the first metatarsal.
The innervation of the muscle is the deep peroneal branch of the fibular nerve.
