Video - Fascia, vessels, and nerves of the lower limb

Veins of the lower limb also fall into two main categories, the superficial and deep veins. The superficial veins pass are those found within the subcutaneous tissue, whereas the deep veins are located in the deep fascia and move along major arteries.

Arteries of the lower limb originate from a branch of the common iliac artery called the external iliac artery. Right behind the inguinal ligament, the external iliac artery becomes the femoral artery, which also becomes the popliteal artery at the level of the adductor canal. The popliteal artery gives rise to the anterior tibial, posterior tibial, and fibular arteries, which supply the leg and foot.

Regarding the innervation of the lower limb, the lumbosacral plexus made of the lumbar (T12 �L4) and the sacral (L4 �S4) plexuses, provides the innervation, the motor innervation of the lower limb mainly originate from obturator nerve, the femoral nerve, and the sciatic nerve and its branches.
