Which bone of the forearm is larger and located on the side of the little finger?

The ulna is the larger bone of the forearm that is located on the side of the little finger. In anatomical terms, the ulna is positioned medially when you are in the standard anatomical position, meaning that when a person stands with their palms facing forward, the ulna will be on the inner side, which aligns with the little finger.

This bone is characterized by its long, cylindrical shape and is crucial in forming part of the elbow joint and the wrist joint. The ulna also has several important features, including the olecranon, which articulates with the humerus to form the elbow, and a notch that accommodates the radius at the wrist.

The radius, in contrast, is located on the thumb side of the forearm and is generally shorter than the ulna. The mention of the humerus refers to the bone of the upper arm, while the metacarpals are the bones of the hand that connect to the fingers. Understanding the distinct roles and placements of these bones aids in comprehending human anatomy and function more effectively.
