is a large muscle located in the inner thigh region of the human body. It’s part of the group of muscles known as the adductors, which are responsible for moving the thigh toward the midline of the body (adduction). It plays a key role in various leg movements, including bringing the legs together and stabilizing the hip joint.
This muscle has both adductor and hamstring components, as it not only helps in thigh adduction but also assists in hip extension (moving the thigh backward) and knee flexion (bending the knee). It’s an important muscle for activities such as walking, running, and maintaining balance during various lower-body movements.

Gracilis
is a muscle located in the inner thigh of the human leg. It’s part of the adductor muscle group, which is responsible for moving the thigh toward the midline of the body (adduction). The “longus” in its name indicates that it’s a relatively long muscle.
The primary function is to pull the thigh inward, towards the center of the body. This muscle plays a crucial role in various leg movements, including actions like bringing the legs together, especially during activities such as walking, running, and maintaining balance. It’s an important muscle for stability and coordination in the lower body.

The adductor Longus
is a muscle located in the inner thigh of the human leg. It is part of the adductor muscle group, which is responsible for moving the thigh toward the midline of the body (adduction). The “brevis” in its name indicates that it’s a relatively short muscle compared to some of the other adductor muscles.
The primary function is to pull the thigh inward, toward the center of the body. This muscle assists in various leg movements, including actions like bringing the legs together, especially during activities such as walking, running, and maintaining balance. Like other adductor muscles, it plays an important role in lower body stability and coordination.
