Extension

Extension is a term used in various fields of medicine, including anatomy, physiology, and pathology. It refers to the process or action of increasing the angle between two body parts, or the straightening out of a flexed limb or organ.

Anatomy

In anatomy, extension is a movement that increases the angle between two body parts. For example, when standing up, the knees are extended. Extension of the hip or shoulder moves the limb backward (posteriorly).

Physiology

In physiology, extension is a type of movement that increases the angle between the body parts. For example, extending the elbow involves increasing the angle between the humerus and the ulna.

Pathology

In pathology, extension refers to the spread of a disease from its primary site to other areas of the body. For example, cancer can extend from its original location to other organs or tissues.
