Which term is defined as "turning the joint outward"?

Abduction
Adduction
External rotation
Internal rotation

The correct answer is: Abduction

Abduction is the correct term for rotating a joint outward. This means to move a body part away from the body's midline, such as lifting the arm away from the side of the body. Adduction, on the other hand, is the opposite - it refers to moving a body part towards the body's midline. External rotation is a term that describes rotation away from the center of the body, while internal rotation refers to rotation towards the center of the body. Therefore, neither external rotation nor internal rotation fully align with the definition of "turning the joint outward." By process of elimination, it can be concluded that abduction is the correct answer.
