The term "gracilis" refers to a muscle in the human body, specifically known as the gracilis muscle. It is a long, thin muscle located in the inner thigh and is part of the adductor group of muscles. The primary function of the gracilis is to assist in the adduction of the thigh, which means it helps bring the leg closer to the body's midline. It also plays a role in flexing the knee. In addition to its anatomical significance, the gracilis muscle is often studied in the context of anatomy and physiology. It is innervated by the obturator nerve and receives blood supply from the femoral artery. Understanding the gracilis is important for fields such as sports medicine and rehabilitation, as it can be involved in various injuries and conditions affecting the lower body.
