Humerus Location: Anatomy & Function of the Upper Arm Bone

The brachial bone, also known as the humerus, is located in the upper arm. It extends from the shoulder joint (where it connects to the scapula) to the elbow joint (where it connects to the radius and ulna bones of the forearm). The humerus is the longest bone in the upper arm and plays an important role in arm movements such as bending, straightening, and rotating the arm.
