A few words of thanks would be greatly appreciated.

Quadriceps - Definition


Quadriceps is a term derived from the Latin, literally meaning "having four heads". The muscle fibers of any muscle can be divided up into several portions, known as "heads". There are several muscles in the body composed of multiple heads, including those with two, called the biceps; with three, called the triceps; and four, called the quadriceps. The quadriceps is usually the term employed referring to the femoral quadriceps, located on the front of the thigh along the femur. This muscle is essential for walking, as it enables the thigh to flex to the pelvis, as well as the extension of the leg towards the thigh. It is therefore ceaselessly used in many sports, such as football, tennis, cycling, or ice-based sports.
