List of Internal Rotators of the Human Body

The human body consists of numerous muscles that perform the function of internal rotation. Internal rotation, also known as medial rotation, is a rotational movement towards the center of the body. This article provides a comprehensive list of the internal rotators of the human body.

Upper Body

Subscapularis

The subscapularis is a large triangular muscle which fills the subscapular fossa and inserts into the lesser tubercle of the humerus and the front of the shoulder-joint capsule. It is one of the four muscles that comprise the rotator cuff, and it contributes to the internal rotation of the humerus.

Pectoralis Major

The pectoralis major is a thick, fan-shaped muscle situated at the chest (anterior) of the human body. It makes a major contribution to the internal rotation and adduction of the humerus.

Latissimus Dorsi

The latissimus dorsi is a large, flat muscle on the back that stretches to the sides, behind the arm, and is partly covered by the trapezius on the back near the midline. It is responsible for the internal rotation of the shoulder joint.

Lower Body

Gluteus Medius and Minimus

The Gluteus medius and Gluteus minimus muscles are located in the buttocks and serve to medially rotate the hip joint.

Tensor Fasciae Latae

The tensor fasciae latae is a muscle of the thigh. It assists in keeping the balance of the pelvis while standing, walking, or running and it also helps to internally rotate the hip.
