POSTERIOR TIBIAL ARTERY

peroneal branch; the nerve first lies on the medial, and for the rest of its course on the lateral 

 side of the vessel. It is accompanied by two veins, which send numerous anastomosing branches 

 across it. In the lower third of the leg the artery is superficial, being covered only by the skin 

 and' by the superficial and deep fasciae.

At the medial malleolus it lies beneath the laciniate (internal annular) ligament and abduc- 

 tor hallucis upon the deltoid ligament of the ankle-joint. Here it has the tibialis posterior 

 and flexor digitorum longus in front of it, and the tibial nerve and the flexor hallucis longus be- 

 hind and to its lateral side. 



At times the tibial nerve divides higher than usual, when one branch lies on the medial side 

 of the artery and the other branch on the lateral side.
