Which bone of the forearm is located between the wrist and elbow?

The radius is one of the two long bones in the forearm, situated between the elbow and the wrist. It runs parallel to the ulna, the other bone in the forearm. The radius is located on the thumb side of the forearm, which is significant for understanding movements like pronation and supination, where the palm turns up or down. Its positioning allows it to play a crucial role in connecting to the wrist bones, facilitating a wide range of hand and wrist motions.

In contrast, the humerus is the bone of the upper arm that connects to the shoulder and does not extend to the wrist. The ulna, while also a forearm bone, specifically runs alongside the radius and is more medial, or towards the body. The fibula is not an arm bone; it is one of the two bones in the lower leg, alongside the tibia. This understanding helps clarify the anatomy of the forearm and the role each bone plays in arm movement and function.
