What is the name of the long bone located in the upper arm?

The long bone located in the upper arm is known as the humerus. This bone plays a crucial role in the structure and function of the arm, serving as a pivotal point for muscle attachment and enabling a wide range of arm movements. The humerus extends from the shoulder to the elbow and is characterized by its length and strength, allowing it to support the motions necessary for lifting, throwing, and overall upper limb mobility.

In contrast, the other bones mentioned serve different functions and are located in different areas. The clavicle, or collarbone, connects the arm to the body but is not considered a bone of the upper arm. The radius and ulna are the two long bones found in the forearm, extending from the elbow to the wrist, and while they are essential for forearm movement and stability, they do not pertain to the upper arm itself. Understanding the anatomy of these bones is vital for recognizing their respective roles and functions in the skeletal system.
