What is the term for returning from flexion to the anatomical position?

The term for returning from flexion to the anatomical position is extension. In anatomical terms, flexion refers to a bending movement that decreases the angle between two body parts, such as bending the elbow or knee. When the body moves back to the anatomical position, in which the body is upright and the arms are at the sides with palms facing forward, this movement is described as extension. It involves straightening the joint back to its original state after it has been flexed.

For instance, when you extend your arm after bending it, you are effectively moving it from a position of flexion back to an upright position, which illustrates the concept of extension. This term is crucial in understanding joint movements, as it describes the opposite of flexion and is foundational for conveying actions related to human movement in fitness and bodily mechanics.
