Oral mucosa sensory nerves (null)

The oral mucosa sensory nerves comprise a diverse population of sensory fibers and endings innervating the mucosal surfaces of the mouth, including the tongue, cheeks, lips, gums, and palate. These nerve fibers encompass mechanoreceptors (such as Merkel cell-neurite complexes, Meissner’s corpuscles, Krause end bulbs), free nerve endings, gustatory afferents, and other specialized structures, mainly originating from branches of the trigeminal, facial, glossopharyngeal, and vagus nerves. The primary function of these nerves is to detect and relay mechanical, thermal, pain, and taste stimuli, critical for oral activities such as feeding, speech, and reflex actions. Key molecular mechanisms include expression of ion channels (e.g. Piezo2 for mechanosensation, TRPV1 for noxious heat). Rather than being a single druggable target, this designation encompasses a complex neuroanatomical and molecular system, which can be subdivided into individual molecular targets such as Piezo2 for mechanical sensation, or TRPV1 for pain.
