Which bone is located on the pinky finger side of the lower arm?

The ulna is the bone located on the pinky finger side of the lower arm. In the context of human anatomy, the forearm consists of two main bones: the radius and the ulna. The ulna is positioned on the side opposite to the thumb, making it align with the pinky finger.

Understanding the role and position of these bones is crucial for various activities, including those in esthetics that may involve manual techniques and movements. The radius, in contrast, is located on the thumb side and plays a pivotal role in wrist movement alongside the ulna. The scapula and clavicle are bones associated with the shoulder girdle and do not pertain to the lower arm's structure.
