Latin muscle parts
Crural muscle – posterior compartment – deep group
The English name for this muscle is the muscle of the ham of the knee. The word popliteus comes from the Latin poples meaning “the ham of the knee.” This refers to the hollow part of the knee behind the knee joint.
Popliteal groove on the lateral surface of the lateral condyle of the femur, the lateral side of the lateral meniscus, and the arcuate popliteal ligament of the joint capsule of the knee.
Triangular posterior surface of the tibia above the soleal line.
Medially rotates tibia on the femur; unlocks the hyperextended knee, retracts the lateral meniscus to prevent it from getting crushed during knee flexion; reduces the load on the posterior cruciate ligament to help prevent anterior dislocation of the femur.
Tibial nerve (L4, L5, and S1)
The muscle is supplied by direct muscular branches and the sural branches of the popliteal artery, the medial and lateral inferior genicular arteries, and the posterior tibial recurrent artery.
