The bicep has several functions, the most important being to rotate the forearm and to flex the elbow. The bicep is a well known muscle, as it lies fairly superficially, and is often well-defined even in non-athletes. The muscle is popular amongst bodybuilders, and can grow quite large through weight training. The Triceps The triceps is called a three headed muscle because there are three bundles of muscle; each of different origin, joining together at the elbow is the large muscle on the back of the human upper limb. It is the muscle principally responsible for extension of the elbow joint. The Quadriceps The quadriceps are also called the four-headed muscle of the femur, also called simply the quadriceps, quadriceps extensor, is a large muscle group that includes the four prevailing muscles on the front of the thigh. It is the great extensor muscle of the knee, forming a large fleshy mass which covers the front and sides of the femur. It is the strongest and leanest muscle in the human body. The Hamstrings In human anatomy, the hamstring refers to one of the three posterior thigh muscles, or to the tendons that make up the borders of the space behind the knee. In modern anatomical contexts, however, they usually refer to the posterior thigh muscles. The Gastronomies Gastronomies are the two-headed muscle you can feel at the back of your calf. The Gastronomies is the calf muscle that is visible from the outside of the body. It attaches to the heel with the Achilles tendon and originates behind the knee on the femur, crossing two joints.
