Overview

Range of motion (ROM) is the term that describes the specific movements or motions that each muscle is capable of performing.

Explanation

Learning Outcomes

Muscles throughout the body are capable of many different movements or motions. Many muscle movements may be described in reference to the planes of the body. In addition, these movements may also be related to changes from the normal anatomical position. Other descriptions simply describe a given movement. Flexion is the term used to describe movements that lessen, or decrease, the angle between two muscles or joints in the human body.
