Shoulder flexion is defined as moving the arm forward toward an overhead position.

• A. Shoulder Flexion
• B. Shoulder Extension
• C. Shoulder Abduction
• D. Shoulder Adduction

Answer: (A)

Shoulder flexion is about moving the arm forward and upward toward an overhead position. In the shoulder, flexion is a forward, lifting motion in the sagittal plane that brings the arm in front of the body and up toward the head. This is why describing the arm moving toward overhead fits flexion.

By comparison, extension is the opposite: moving the arm backward from the front of the body. Abduction is lifting the arm away from the midline of the body to the side, and adduction is bringing it back toward the body. So the described motion specifically matches shoulder flexion.
