sural artery
The sural arteries (inferior muscular arteries) are two large branches, which are distributed to the Gastrocnemius, Soleus, and Plantaris. The term applies to any of four or five arteries arising from the popliteal artery, with distribution to the muscles and integument of the calf, and with anastomoses to the posterior tibial, medial and lateral inferior genicular arteries.
