Anterior and Medial Thigh

Question 1

Musculovenous pump

Answer 1

muscle contracts, compressing vein and propelling blood toward heart; valves prevent backflow of blood (unidirectional)

Question 2

How does the fascia of the leg aid the action of the musculovenous pump?

Answer 2

Fascia lata and crural fascia limit expansion of muscles during contraction -> forcing muscle to expand inwards and press on the veins
