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.
Figure 1. Comparative anatomy of giraffe blood vessels A, posterior tibial artery. B, carotid artery at the angle of the jaw. Each vessel has an outside diameter of 3 mm. The wall thickness of the posterior tibial artery is 7 times greater than it is in the carotid artery and the lumen is 6-fold smaller.he implication of these observations is that Cushing's mechanism elevates basal MAP when either cerebral blood flow is threatened by neck elongation in the giraffe, or when resistance within brainstem feeder arteries in man and SHR is increased.
