Latin: Musculus tibialis anteriorThe anterior tibial muscle owes its name to its location at the front of the lower leg. It acts as an antagonist of the twin calf muscle and the posterior tibial muscle and causes pure dorsiflexion (bringing the toes closer to the knee).
Approach, Origin, Innervation
Approach: Medial and plantar surface of the 1st sphenoid bone (Os cuneiforme I) and 1st metatarsal bone (Os metatarsale I) Origin: Lateral surface of the tibia (Condylus et facies lateralis tibiae) and interosseous membrane (Membrana interossea) Innervation: N. peroneus profundus, L 4 – 5, S 1When the anterior tibial muscle is stretched, the tip of the stretched lower leg must be extended (stand on the tips of the ten). This results in a shortening of the twin calf muscle.
