Verified step by step guidance

Step 1: Understand the terminology related to body movements. Flexion refers to the action of bending a joint, which decreases the angle between two body parts. For example, bending the elbow or knee is flexion.

Step 2: Compare flexion with other terms provided in the options. Rotation refers to the movement of a body part around its axis, such as turning the head side to side. Extension is the opposite of flexion, where the angle between two body parts increases, such as straightening the elbow or knee. Abduction refers to moving a body part away from the midline of the body, such as raising the arm sideways.

Step 3: Identify the correct term based on the description of bending a body part. Since bending decreases the angle between two body parts, the correct term is flexion.

Step 4: Review examples of flexion in the body to reinforce understanding. Examples include bending the fingers to make a fist, bending the knee to bring the heel closer to the buttocks, or bending the neck to look down.

Step 5: Practice distinguishing flexion from other movements by visualizing or performing actions like rotating the head, extending the arm, or abducting the leg to solidify the concept.
