What is the name of the upper arm bone?

The upper arm bone is called the humerus. It is the long bone that runs from the shoulder to the elbow, playing a crucial role in the structure and function of the arm. The humerus provides attachment points for numerous muscles that facilitate movement, including those responsible for raising and lowering the arm, as well as rotating it.

In contrast, the radius and ulna, which are located in the forearm, connect with the humerus at the elbow joint but do not comprise the bone of the upper arm itself. The clavicle, or collarbone, connects the arm to the body but is not part of the upper arm structure. Understanding the anatomy of the upper limb and the specific functions of each bone is essential for anyone training in fields related to health or combat medicine.
