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.
All three begin at one common tendon attached to the ischial tuberosity of the pelvis (sit bones). The semimembranosus and semitendinosus connect to the tibia on the inside of the leg, and the biceps femoris connects to the top of the fibula on the outside of the leg. These muscles flex, or bend, the knee.his tendon continues below the patella to connect to the tibia. These muscles extend, or straighten, the knee. The hamstrings are the muscles on the back of the thigh. This muscle group is composed of the biceps femoris (outside), the semimembranosus, and the semitendinosus (inside).
