What is the name of the inner and larger bone of the forearm located on the side of the little finger?

The ulna is the name of the inner and larger bone of the forearm, specifically located on the side opposite to the thumb, which corresponds to the side of the little finger. It runs parallel to the radius, which is the smaller bone of the forearm found on the thumb side. The ulna plays a crucial role in the structure and function of the forearm and elbow joint. It contributes to the stability of the wrist and provides points of attachment for muscles that facilitate various movements of the arm and hand. Understanding the anatomy of the forearm bones, particularly their positions and relationships to one another, is vital in fields such as cosmetology, especially when performing tasks that require manual dexterity and precision.

The other options refer to different structures that don't fulfill this specific definition. The radius, while also a forearm bone, is positioned on the thumb side and does not meet the criteria of being the larger bone on the side of the little finger. Both the scaphoid and carpal refer to bones within the wrist anatomy and are not related to the forearm structure directly.
