Medial rotation of the forearm is called pronation in its broadest sense, so "medial rotation of the arm" most probably refers to movement at the shoulder.
The best example is if you flex your forearm at 90° to your arm, and you bring your hand to your midline, this is medial rotation of the arm at the shoulder.
Medial rotation of the arm is the rotation of the humerus(arm bone) around its long axis (imagine a line from elbow to shoulder).

What muscle is the main antagonist of medial rotation of the humerus?
deltoid
Which ligament at the knee protects it from lateral rotation?
ACL and medial meniscus.
Is the hand lateral to the wrist?
No. When the body is in the anatomical position, the thumb is further away from the midline. You say that the thumb is lateral to the ring finger.
What would Positive apley's compression test with lateral rotation mean?
This testing positive with a lateral rotation would mean the patient probably has a medial meniscal injury.
Is the heart medial or lateral to left lung?
Yes, the heart is medial to the ribs. The ribs are lateral to the heart.
What is leg medial rotation?
Leg medial rotation refers to the movement of the leg towards the midline of the body. This movement occurs mainly at the hip joint, where the femur rotates inward. Leg medial rotation is important for actions such as crossing one leg over the other while sitting.
The medial rotation is the movement of which joint?
The medial rotation is the movement of the shoulder joint. During this movement, the arm is rotated towards the midline of the body.
What are the special terms used to describe medial and lateral rotation of the forearm?
radius (lateral) Ulna (medial)
What muscle is the main antagonist of medial rotation of the humerus?
deltoid
What muscles are used in hip medial rotation?
Knee Rotation:- as extension progresses, shorter, more highly curved lateral condyle exhausts its articular surface andis checked by ACL, whereas larger and less curved medial condyle continues its forwardroll & skids backward, assisted by tightening of PCL;- result is a medial rotation of femur (external tibial rotation) that tightens collateral ligaments, & joint is "screwed home",to use mechanical phraseology;- flexion of extended knee is preceded by lateral rotation of femur (or medial rotation of tibia), usually produced by popliteus;- this rotation relaxes the tension of the collateral ligaments sufficiently to permit flexion;
What is the action of the startorius muscles?
Flexion, abduction, and lateral rotation at the hip, and flexion and medial rotation at the knee.
Which ligament at the knee protects it from lateral rotation?
ACL and medial meniscus.
What is the capsular pattern of shoulder joint?
Abduction, lateral and medial rotation
If the medial hip rotators are tight what action will they impede?
Tight medial hip rotators may impede external rotation of the hip joint. This can limit the ability to rotate the hip outward, leading to decreased range of motion and potential compensations in gait and movement patterns. Stretching and strengthening exercises can help improve flexibility and function of the hip rotators.
What are Three principal axis of rotation for the human body?
longitudial transverse and medial
What are the 9 movements of the shoulder joint?
Movement>prime mover. Abduction>deltoid. Adduction>gravity. Flexion>pectoralis major(sternal part). Extension>teres major. Medial rotation>pectoralis major(sternal). Lateral rotation>infraspinatus.
Where is the supraspinatus muscle originates in the medial rotation of the scapula?
Center of the shoulderblade and attaches to the spine.
