The major muscles in the upper leg are the hamstrings and quadriceps. The hamstrings are three muscles at the back of the thigh that affect hip and knee movement. The quadricepsâthe strongest and leanest muscles in the bodyâare a four-muscle group at the front of the thigh that work to extend the knee and lower leg. The knee is a pivot-like hinge joint in the leg that connects the bones in the upper and lower leg. It is the largest joint in the human body.
The leg is composed of five distinct sections: upper leg, knee, lower leg, ankle, and foot. The upper leg begins at the hip and continues down to the knee. The only bone in this region is the femur, the largest bone in the body. The femurâs head creates the ball of the ball-and-socket-style hip joint.The base of the femur makes up part of the knee.any muscles that power foot movements begin as high up as the back of the knee and extend down to the foot. Possibly the most important structure in the lower leg is the Achilles tendon. It connects three musclesâthe plantaris, calf, and soleusâto the heel bone.
