Your humerus is located in your upper arm, specifically between the shoulder and the elbow.
The Humerus Bone: A Detailed Look
The humerus is a long bone with key functions in arm movement. Let's explore its location and connections:
- Location: The humerus sits in the upper arm region. It's the largest bone in the arm.
- Proximal Connection: The upper end of the humerus (proximal humerus) forms the shoulder joint. It connects to the shoulder through the glenoid fossa of the scapula. This joint is known as the glenohumeral joint.
- Distal Connection: The lower end of the humerus (distal humerus) forms the elbow joint, connecting with the bones of the forearm.
Key Anatomical Points
| Point | Description |
|---|---|
| Location | Upper arm, between the shoulder and elbow. |
| Proximal End | Connects to the scapula at the glenohumeral joint (shoulder joint). |
| Distal End | Connects to the bones of the forearm at the elbow joint. |
Function of the Humerus
- Supports movement of the arm.
- Anchors major muscles of the shoulder and arm.
- Allows for a wide range of motion in the arm.
The humerus is essential for a wide variety of arm movements, from delicate tasks to powerful actions.
