Which nerve is also known as the dorsal cutaneous nerve?

The dorsal cutaneous nerve is referred to with specificity in relation to its function and anatomical location. It primarily provides sensory innervation to the skin on the dorsal (back) side of the hand and fingers. This nerve branches from the ulnar nerve and extends to supply sensation to the skin in these areas.

In the context of the choices provided, recognizing the dorsal cutaneous nerve aligns directly with the name 'dorsal nerve,' which signifies its primary role in sensory perception of the dorsal part of the hand. Understanding this concept is crucial for nail technicians, as proper knowledge of nerve anatomy can aid in performing safe and effective nail services while avoiding unnecessary discomfort for clients.

The other options don't accurately represent the nerve in question. The median nerve primarily serves the anterior forearm and is involved in finger flexing, while the digital nerve pertains specifically to the nerves supplying sensation to individual fingers. The ulnar nerve does contribute to sensory and motor functions, but it is not synonymous with the term "dorsal cutaneous nerve." Therefore, recognizing the precise association with "dorsal nerve" becomes essential in the context of understanding the anatomical and functional relationships of hand nerves for the profession.
