Branches
The branches of the anterior tibial artery are:
- post. tibial recurrent artery
- ant. tibial recurrent artery
- muscular branches
- anterior medial malleolar artery
The anterior medial malleolar artery arises about 5 cm. above the ankle-joint and passes behind the tendons of the Extensor hallucis longus and Tibialis anterior, to the medial side of the ankle, upon which it ramifies, anastomosing with branches of the posterior tibial and medial plantar arteries...
- anterior lateral malleolar artery
The anterior lateral malleolar artery passes beneath the tendons of the Extensor digitorum longus and Peronæus tertius and supplies the lateral side of the ankle, anastomosing with the perforating branch of the peroneal artery, and with ascending twigs from the lateral tarsal artery.-External...
