Arm bones - Definition

June 2017


Definition

A precise description of the arm is the anatomical part of the body located between the shoulder and elbow joints. Consequently, the arm is composed of only one bone: the humerus. Nevertheless, the term is often used incorrectly in simplified language to define the entire limb from the shoulder to the wrist. In this context, the forearm is included, located between the elbow and wrist, which is comprised of two bones. The radius is located on the side of the thumb, on the outer or lateral side of the forearm, while the ulna is located on the inner or medial side of the forearm. Easily exposed to impact when subjected to trauma, the bones of the arm and forearm are the most frequently fractured, a condition that is easily healed by immobilizing the arm for several weeks if the bones have not been displaced, or by surgery if this is the case.
