Humerus - English Definition & Meaning

Definition

The humerus is the long bone in your upper arm, running from your shoulder to your elbow. Think of it as the primary support structure of your upper arm. It connects to the scapula (shoulder blade) at the shoulder joint and to the radius and ulna (forearm bones) at the elbow joint. It is essential for a wide range of arm movements, including lifting, throwing, and rotating. Fractures of the humerus can significantly impair arm function. Basically, it's your arm's main structural component!
