Final answer:
The thigh muscle is divided into medial, anterior, and posterior compartments. The adductor muscles in the medial compartment adduct the thigh, while the quadriceps femoris in the anterior compartment extends the knee. The hamstrings in the posterior compartment flex the knee.
Step-by-step explanation:
The thigh muscle is composed of different compartments, including the medial, anterior, and posterior compartments. The medial compartment of the thigh contains adductor muscles, such as the adductor longus, adductor brevis, adductor magnus, and pectineus. These muscles are responsible for adducting the femur at the hip joint.
The anterior compartment of the thigh comprises the quadriceps femoris, which consists of four muscles: rectus femoris, vastus lateralis, vastus medius, and vastus intermedius. The quadriceps femoris helps to extend the knee joint.
The posterior compartment of the thigh is made up of the hamstrings, which include the biceps femoris, semitendinosus, and semimembranosus. These muscles flex the knee joint.
