ANATOMY

Detailed explanation-1: -Hyperextension is the abnormal or excessive extension of a joint beyond its normal range of motion, thus resulting in injury. Similarly, hyperflexion is excessive flexion at a joint. Hyperextension injuries are common at hinge joints such as the knee or elbow.

Detailed explanation-2: -Hyperextension refers to a joint that has a greater than normal range of motion, and most commonly occurs within the elbow and knee. Joints have a predetermined range of motion available, and that range is determined by muscle length, bone size, cartilage and ligaments.

Detailed explanation-3: -Hyperextension of the elbow occurs when your elbow joint bends too far backward, beyond being fully straight.

Detailed explanation-4: -Straightening a limb after flexion is an example of extension. Extension past the normal anatomical position is referred to as hyperextension. This includes moving the neck back to look upward or bending the wrist so that the hand moves away from the forearm.

Detailed explanation-5: -Extension This is a straightening movement that results in the increase of the angle in a joint by moving bones further apart. This movement occurs in the sagittal plane and is the reverse movement to flexion.
