GENERAL HISTOLOGY

Detailed explanation-1: -Veins from the calf muscles drain into posterior tibial veins. They also receive connections from the superficial veins and the fibular veins. The fibular veins are also formed by the medial and lateral plantar veins and run with the fibular artery.

Detailed explanation-2: -The posterior tibial vein receives blood from the medial and lateral plantar vein and drains the posterior compartment of the leg and plantar surface of the foot. This vein lies behind the tibia and joins the popliteal vein at the posterior knee.

Detailed explanation-3: -In the lower extremities, deep system consists of the anterior and posterior tibial veins and peroneal vein. These veins drain into the popliteal vein and eventually into the superficial femoral vein.

Detailed explanation-4: -The majority of the foot is drained by the small saphenous vein. The small saphenous vein begins at the lateral end of the dorsal venous arch. It then courses posterior to the lateral malleolus, ascending on the posterior side of the leg, running with the sural nerve before emptying into the popliteal vein.
