The ulna is one of the two long bones in your forearm, along with the radius. It's located on the pinky finger side of your arm, running from your elbow to your wrist. The ulna plays a crucial role in moving your arm, wrist, and hand, and it also supports important muscles, tendons, and ligaments.
Here's a breakdown of the ulna's key features:
- Location: Medial side of the forearm (same side as the pinky finger)
- Articulation: Connects with the humerus (upper arm bone) at the elbow joint and the radius at both the elbow and wrist.
- Function: Provides structural support for the forearm, contributes to hand and wrist movements, and serves as an attachment point for muscles.
Understanding the ulna's anatomy and function is important for diagnosing and treating injuries like fractures or dislocations.
