Dorsalis pedis artery (Arteria dorsalis pedis) The dorsalis pedis artery, also known as the dorsal artery of the foot, is the continuation of the anterior tibial artery distal to the ankle joint.It is located on the dorsum of the foot, just deep to the inferior extensor retinaculum and lies between the extensor hallucis longus tendon and the medial tendon of the extensor digitorum longus muscle. Why would certain bacteria be drawn to the membranes of the dorsal cavity (Meningitis)? The meninges of the brain extend down the dorsal cavity to protect the spinal cord, as seen in the image below.
