The mental nerve is a sensory nerve of the face. It is a branch of the posterior trunk of the inferior alveolar nerve, itself a branch of the mandibular nerve (CN V 3), itself a branch of the trigeminal nerve (CN V).

Additionally, the receptive field neurons in this nerve pathway showed spontaneous firing in low-threshold nociceptors, suggesting that nerve damage can cause dysesthesia. In women with chronic pain or itchy scalps without any apparent physical cause, about half had from psychiatric disorders.
