MICROANATOMY

Detailed explanation-1: -The popliteal artery sits behind the knee in the popliteal fossa and bifurcates into the anterior and posterior tibial arteries near the distal border of the popliteus muscle. The anterior tibial artery passes anterior to the popliteus muscles and passes between the tibia and fibula through the interosseous membrane.

Detailed explanation-2: -The peroneal artery (also termed the fibular artery) is the posterior lateral branch of the tibial-peroneal trunk in the lower extremity just distal to the popliteal fossa. The peroneal artery (along with the anterior tibial artery) is the vascular supply to the lateral compartment of the lower leg.

Detailed explanation-3: -Vascular Anatomy. The anterior tibial artery emerges from the popliteal artery about 3 cm under the knee joint at the distal border of the popliteus muscle and passes proximal to the interosseous membrane to the extensor site of the lower extremity.

Detailed explanation-4: -The bony pelvis and lower limbs receive vascular supply from the distal continuations of right and left common iliac arteries. The primary blood supply to the bony pelvis is from the divisions of iliac arteries while the lower limbs receive supply via obturator artery and divisions of the common femoral artery.

Detailed explanation-5: -There are usually five of them, each dividing into anterior and posterior divisions that together supply the skin and fascia of the posterior leg. The communicating branch emerges above the distal end of tibia deep to flexor hallucis longus muscle.
