The sartorius muscle is the longest muscle in the body. It runs from the hip down to the knee and is involved in hip flexion, knee flexion, and rotating the thigh. The gracilis muscle is a long, thin muscle that also runs from the hip down to the knee but is not as long as the sartorius. The quadriceps femoris muscle is a group of four muscles located in the front of the thigh and is not considered the longest muscle in the body. The biceps brachii and brachioradialis muscles are located in the arm and forearm, respectively, and are not considered the longest muscle in the body.
