Verified step by step guidance

1. Step 1: Understand the concept of joint movement. Joints allow bones to move relative to each other, and specific terms describe these movements based on the direction and angle of motion.
2. Step 2: Define 'flexion.' Flexion refers to a movement that decreases the angle between two bones at a joint, such as bending the elbow or knee.
3. Step 3: Define 'extension.' Extension is the opposite of flexion and refers to a movement that increases the angle between two bones at a joint, such as straightening the elbow or knee.
4. Step 4: Define 'rotation.' Rotation refers to a movement where a bone pivots or revolves around its own axis, such as turning the head side to side.
5. Step 5: Define 'abduction.' Abduction refers to a movement that takes a limb away from the midline of the body, such as raising the arm sideways.
