What is the result of medial rotation in joints?

Movement of the joint away from the midline
Inward rotation towards the center of the body
Movements involving no rotation
Outward hip and shoulder rotation

The correct answer is: Inward rotation towards the center of the body

Medial rotation in joints refers to the inward rotation of a limb or body part towards the center of the body. This movement is commonly observed at the shoulder and hip joints, where the body becomes oriented towards its midline. For instance, when the arm is medially rotated, the forearm and hand move closer to the center of the body, illustrating how a joint can pivot inward. This is significant in many physical activities and rehabilitation exercises, emphasizing the importance of understanding joint mechanics. In contrast, movements away from the midline or those that entail no rotation at all do not involve medial rotation. Outward rotation, or lateral rotation, signifies movement away from the center, which is fundamentally different from the inward motion defined by medial rotation.
