The bone in your arm that extends from your shoulder to your elbow is the humerus.
Understanding the Humerus
The humerus is a long bone, the only bone in the upper arm. It's crucial for arm movement and plays a key role in shoulder and elbow joint function.
- Location: It connects to the scapula (shoulder blade) at the shoulder joint and the radius and ulna (forearm bones) at the elbow joint.
- Function: The humerus allows for a wide range of arm movements, including flexion, extension, abduction, adduction, and rotation.
- Structure: It's a long bone with a distinct head, shaft, and distal end (near the elbow).
As stated in the provided reference, "The humerus — also known as the upper arm bone — is a long bone that runs from the shoulder and scapula (shoulder blade) to the elbow."
