The tibialis posterior is the most central of all the leg muscles, and is located in the deep posterior compartment of the leg.It is the key stabilizing muscle of the lower leg. Blood is supplied to the muscle by the posterior tibial artery, and innervation is via the tibial nerve.he tendon of the tibialis posterior muscle (sometimes called the posterior tibial tendon) descends posterior to the medial malleolus and terminates by dividing into plantar, main, and recurrent components.
In cases of a high origin, the anterior tibial may lie deep to the popliteus muscle (hence compressed against the tibia) or between this muscle and the oblique popliteal ligament. With high origin it gives rise to branches normally originating from the popliteal and the peroneal arteries. An enlarged anterior tibial may supply both the dorsum of the foot and the plantar arch. The anterior tibial may become plexiform on the dorsum of the foot, giving rise to the dorsal intermetatarsals. The tibialis anterior artery may be continuous with the peroneal in those cases where the anterior tibial is weak; this represents an early embryonal stage of development.
