Anatomy
Anatomy is a branch of biology and medicine that is the consideration of the structure of living things. It is a general term that includes human anatomy, animal anatomy , and plant anatomy...

, internal rotation (also known as medial rotation) is rotation towards the center of the body.

The muscles of internal rotation include:
  • of arm
    Arm
    In human anatomy, the arm is the part of the upper limb between the shoulder and the elbow joints. In other animals, the term arm can also be used for analogous structures, such as one of the paired forelimbs of a four-legged animal or the arms of cephalopods...

    Humerus
    The humerus is a long bone in the arm or forelimb that runs from the shoulder to the elbow....

     at shoulder
    Shoulder
    The human shoulder is made up of three bones: the clavicle , the scapula , and the humerus as well as associated muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder joints. The major joint of the shoulder is the glenohumeral joint, which...

    • Deltoid muscle
      Deltoid muscle
      In human anatomy, the deltoid muscle is the muscle forming the rounded contour of the shoulder. Anatomically, it appears to be made up of three distinct sets of fibers though electromyography suggests that it consists of at least seven groups that can be independently coordinated by the central...

    • Subscapularis
    • Teres major
    • Latissimus dorsi
    • Pectoralis major
    • Biceps Brachii

  • of thigh
    Thigh
    In humans the thigh is the area between the pelvis and the knee. Anatomically, it is part of the lower limb.The single bone in the thigh is called the femur...

    /femur
    Femur
    The femur , or thigh bone, is the most proximal bone of the leg in tetrapod vertebrates capable of walking or jumping, such as most land mammals, birds, many reptiles such as lizards, and amphibians such as frogs. In vertebrates with four legs such as dogs and horses, the femur is found only in...

     at hip
    • Tensor fasciae latae
      Tensor fasciae latae
      The tensor fasciae latae or tensor fasciæ latæ is a muscle of the thigh. The English name for this muscle is the muscle that stretches the band on the side...

    • Gluteus medius
    • Gluteus minimus

  • of leg
    Human leg
    The human leg is the entire lower extremity or limb of the human body, including the foot, thigh and even the hip or gluteal region; however, the precise definition in human anatomy refers only to the section of the lower limb extending from the knee to the ankle.Legs are used for standing,...

     at knee
    Knee
    The knee joint joins the thigh with the leg and consists of two articulations: one between the fibula and tibia, and one between the femur and patella. It is the largest joint in the human body and is very complicated. The knee is a mobile trocho-ginglymus , which permits flexion and extension as...

    • Semimembranosus
    • Semitendinosus

  • of eyeball (motion is also called "intorsion" or incyclotorsion
    Incyclotorsion
    - Physiology :Incyclotorsion is a term applied to the inward, torsional movement of the eye, mediated by the superior oblique muscle of the eye...

    )
    • Superior rectus muscle
      Superior rectus muscle
      The superior rectus muscle is a muscle in the orbit. It is one of the extraocular muscles. It is innervated by the superior division of the oculomotor nerve...

    • Superior oblique muscle
      Superior oblique muscle
      For the abdominal muscle see: Abdominal external oblique muscleThe superior oblique muscle, or obliquus oculi superior, is a fusiform muscle originating in the upper, medial side of the orbit which abducts, depresses and internally rotates the eye...
