Published in Anatomy 1 min read

The labial nerve provides sensation to the lips. More specifically, the superior labial nerve, a branch of the infraorbital nerve, innervates the upper lip.

Function of the Superior Labial Nerve

The primary function of the superior labial nerve is sensory. This means it is responsible for transmitting sensations from the upper lip to the brain.

  • Sensation: The superior labial nerve allows you to feel touch, temperature, and pain in your upper lip.
  • Areas Served: It supplies sensation to both the skin and the mucosa (the inner lining) of the upper lip.
