Pronation is a inward rotation of the arm or the foot, supination is an outward rotation (the opposite).Pronation roughly means downward facing. Examples of this would be turning your palms down towards the floor or lying on your stomach.
The medial roataion is the movement of Glenohumeral joint .
Abduction, lateral and medial rotation
If medial hip rotators are tight, then they will impede lateral hip rotation because lateral hip rotation requires the medial hip rotators to stretch to allow the lateral hip rotators to contract and rotate the hip laterally.
longitudial transverse and medial
There are many: extension, flexion, supination, pronation, abduction, adduction, lateral rotation, medial rotation, circumduction, elevation, depression, protraction, retraction, inversion, eversion, and opposition.
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).
Pronation is a inward rotation of the arm or the foot, supination is an outward rotation (the opposite).Pronation roughly means downward facing. Examples of this would be turning your palms down towards the floor or lying on your stomach.
"medial" means towards the center of the body. "rotation" connotes movement.

deltoid
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;
Pronation of the hand results in the distal end of the radius being medial to the ulna and the palms facing backward or downward. This position is in contrast to the supination of the anatomic position.
Flexion, abduction, and lateral rotation at the hip, and flexion and medial rotation at the knee.
