The gastrocnemius muscle (plural gastrocnemii) is a superficial two-headed muscle that is in the back part of the lower leg of humans. It is located superficial to the soleus in the posterior (back) compartment of the leg .
The deep veins of the lower limb include the common femoral vein, femoral vein, and the deep femoral vein; the popliteal vein, the tibial, and fibular veins. In the common femoral vein one valve is located above the saphenofemoral junction called the suprasaphenic valve .
Others have the name of the deep vein where they drain: Medial gastrocnemius perforator, draining into the gastrocnemius vein; Fibular perforators, usually two, one superior near the lateral aspect of the knee and one inferior at the lateral aspect of the ankle
Sometimes, the SSV joins the common gastrocnemius vein before draining in the popliteal vein. [2] Sometimes, it does not make contact with the popliteal vein, but goes up to drain in the GSV at a variable level. [1] Instead of draining in the popliteal vein, it can merge with the Giacomini vein and drain in the GSV at the superior 1/3 of the thigh.
The tributaries of the popliteal vein include: Veins that correspond to branches given off by the popliteal artery (see popliteal artery). the small saphenous vein, which perforates the deep fascia and passes between the two heads of the gastrocnemius muscle to end in the popliteal vein. [1] [2] the fibular veins.
Along the side of the muscle, and superficial to it, is the small saphenous vein. The sural nerve accompanies the small saphenous vein as it descends in the posterior leg, traveling inferolateral to it as it crosses the lateral border of the Achilles tendon. [12] The tendon is the thickest tendon in the human body. [11]
“Our calf muscles are a very efficient pump for squeezing the veins and pushing blood back to our heart,” said Dr. Gregory Piazza, a cardiologist at Brigham and Women’s Hospital in Boston ...
The great saphenous vein (GSV) or long saphenous vein (/ s ə ˈ f iː n ə s /) is a large, subcutaneous, superficial vein of the leg. It is the longest vein in the body, running along the length of the lower limb, returning blood from the foot , leg and thigh to the deep femoral vein at the femoral triangle .
