The Knee and Thigh Flashcards
What fat pad is the largest?
Infrapatellar far pad
What does the Infrapatellar fat pad do?
separates the patellar and tendon from rubbing on the tibia
Femoral Nerve
works quadriceps muscle
Tibial Nerve
works on hamstrings and gastrocnemius
Common Peroneal Nerve
important because it’s very close in surface at fibular head
Popliteal artery
major artery for knee
most of the blood from knee drains into the
small saphenous vein
_______ vein drains small saphenous vein and other blood from knee
Popliteal
After the popliteal vein blood travels to the
femoral vein
