The gracilis muscle is a long, thin muscle located in the inner thigh. It is one of the muscles that make up the adductor group, which is responsible for bringing the legs together. The gracilis originates from the pubic bone and extends down to the tibia, playing a role in both hip and knee movements. This muscle assists in actions such as hip adduction, flexion, and medial rotation of the thigh. It also helps stabilize the knee joint. Due to its position, the gracilis is important for activities like walking, running, and maintaining balance during various movements.
