Final answer:
The adductor magnus, adductor longus, and gracilis are muscles associated with the medial thigh, functioning in adduction and rotation of the thigh and flexion of the leg at the knee.
Step-by-step explanation:
The muscles adductor magnus, adductor longus, and gracilis are associated with the medial thigh. These muscles are situated in the medial compartment of the thigh and are primarily responsible for adducting the femur at the hip. The adductor magnus is noteworthy because it has two parts: an anterior fascicle that adducts, medially rotates, and flexes the thigh, and a posterior fascicle that assists in thigh extension. The adductor longus also adds to the action by adducting, medially rotating, and flexing the thigh. In addition to these actions, the gracilis muscle also contributes by adducting the thigh and flexing the leg at the knee.
