Which bone runs from the point of elbow to the pinky finger?

The ulna is the bone that runs from the elbow to the pinky finger. It is one of the two long bones in the forearm, the other being the radius. The ulna is located on the side of the forearm that aligns with the pinky, making it the primary bone involved in forming the hinge joint at the elbow and providing stability to the inner part of the wrist. Its anatomical structure allows for significant range of motion when bending and straightening the arm.

Understanding the ulna's position is crucial in a clinical setting, especially in chiropractic practice, as it plays a vital role in wrist and forearm mobility and function. This knowledge is essential for chiropractic assistants when working with patients, helping them to appreciate how the ulna interacts within the entire upper extremity.
