What is the large bone on the little finger side of the forearm called?

The large bone on the little finger side of the forearm is known as the ulna. This bone runs parallel to the radius, which is located on the thumb side of the forearm. The ulna plays a crucial role in forming the elbow joint with the humerus at its proximal end and contributes to the wrist joint at its distal end. Its structure provides stability to the forearm and supports various movements. Understanding the anatomy of the forearm, particularly the locations and functions of the ulna and radius, is fundamental for nail technicians, as they often work closely with the hands and may need to understand anatomical references when discussing issues or injuries involving the extremities.
