Final answer:
The Anterior Tibialis is a key muscle located on the front of the tibia responsible for dorsiflexion and inversion of the foot, as well as supporting the foot's arch. It is closely associated with the anterior border of the tibia and receives its blood supply from the anterior tibial artery.
Step-by-step explanation:
The Anterior Tibialis is a muscle of the lower leg located on the front of the tibia. The anterior border of the tibia is a narrow margin extending inferiorly from the tibial tuberosity, which is the elevation on the anterior, proximal end of the tibia where the patellar tendon attaches.
This border can be easily palpated along the length of the tibia. The primary functions of the Anterior Tibialis include dorsiflexion and inversion of the foot at the ankle joint, both critical for the action of walking and maintaining balance. It also helps support the arch of the foot.
The muscle receives its blood supply from branches of the anterior tibial artery, which supplies blood to the tarsal and dorsal regions of the foot.
