Verified step by step guidance1
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.
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.
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.
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.
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.
