Biaxial joints allow movement in two planes. An example is the wrist joint, which enables flexion and extension (bending and straightening) as well as radial and ulnar deviation (side-to-side movement). Another example is the metacarpophalangeal joints (the knuckles), which allow for flexion/extension of the fingers and abduction/adduction (movement away from or towards the midline).
The six primary movements that occur at the joints between body segments are flexion, extension, abduction, adduction, rotation, and circumduction. Flexion is the bending movement that decreases the angle between body parts, while extension is the opposite movement that increases the angle. Abduction is the movement away from the midline of the body, while adduction is the movement toward the midline. Rotation involves the turning or twisting movement, and circumduction is a combination of flexion, extension, abduction, and adduction that creates a circular movement.
Flexion when you pull your forearm towards your body and extension when you extend it away from your body.

When the angle of a joint increases, it produces a movement called "extension." This movement typically occurs in joints such as the knee or elbow, where the angle between the two bones becomes larger. Extension is the opposite of flexion, which decreases the angle between the bones at a joint.

Finger extension
Circumduction movement is a combination of flexion, extension, abduction, and adduction in a circular motion. An example is when you move your arm in a circular motion, such as when winding up to throw a ball. The movement involves all the planes of motion around a joint.
A domain extension is the end of a domain. For example, in the domain [ example.com ], "com" is the extension.
extension
The elbow joint is an example of a hinge joint. It allows movement in only one plane, similar to a door hinge, enabling flexion and extension of the arm.

Extension and flexion are two opposite movements in the human body. Extension refers to straightening or increasing the angle of a joint, while flexion involves bending or decreasing the angle of a joint. For example, when you straighten your arm, you are extending it, and when you bend your arm, you are flexing it.
