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 majority of muscles in the leg are considered long muscles, in that they stretch great distances. As these muscles contract and relax, they move skeletal bones to create movement of the body. Smaller muscles help the larger muscles, stabilize joints, help rotate joints, and facilitate other fine-tuned movements.The largest muscle masses in the leg are present in the thigh and the calf.The muscles that make up the quadriceps are the strongest and leanest of all muscles in the body. These four muscles at the front of the thigh are the major extensors (help to extend the leg straight) of the knee.They are: 1  Vastus lateralis: On the outside of the thigh, this is the largest of the quadriceps.ome of the major muscles of the calf include: 1  Gastrocnemius (calf muscle) : One of the large muscles of the leg, it connects to the heel. 2  It flexes and extends the foot, ankle, and knee. 3  Soleus: This muscle extends from the back of the knee to the heel. 4  It is important in walking and standing.
