Verified step by step guidance

Understand the definitions of flexion and extension in anatomical terms. Flexion refers to a movement that decreases the angle between two body parts, typically bending a joint. Extension is the opposite movement, increasing the angle between body parts, usually straightening a joint.

Consider examples of flexion and extension in the human body. For instance, bending the elbow or knee is flexion, while straightening them is extension.

Analyze the statement 'Extension is the reverse of flexion.' Based on the definitions, determine if extension indeed reverses the action of flexion by increasing the angle that flexion decreases.

Reflect on the anatomical movements involved in various joints, such as the knee, elbow, and fingers, to see if the statement holds true across different parts of the body.

Conclude whether the statement 'Extension is the reverse of flexion' is true or false based on the analysis of the definitions and examples.
