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

The long bone of the upper arm is known as the humerus. This bone extends from the shoulder to the elbow and plays a crucial role in the arm's movement and support. It is characterized by its cylindrical shape and has various important features, such as the head, which articulates with the scapula at the shoulder joint, and the distal end that connects to the forearm bones at the elbow. The humerus serves as an attachment point for muscles that facilitate arm movement, making it integral to many functional activities such as lifting, throwing, and pushing. Understanding the anatomy of the humerus is essential in fields like health science, as it is a key structure in the upper limb’s functionality.
