Ophthalmic, maxillary, and mandibular branches of the trigeminal nerve provide sensory innervation to orofacial tissues. Trigeminal sensory neurons respond to a diverse array of sensory stimuli to generate distinct sensations, including thermosensation, mechanosensation, itching, and pain. These sensory neurons also detect the distinct sharpness or pungency of many foods and beverages. This SnapShot highlights the transduction ion channels critical to orofacial sensation.
三叉神经的眼支、上颌支和下颌支为面颌部组织提供感觉神经支配。三叉神经感觉神经元对多种感觉刺激作出反应，产生不同的感觉，包括温度感觉、机械感觉、瘙痒和疼痛。这些感觉神经元还能感知许多食物和饮料的独特刺激性或辛辣味。本文要点介绍对面颌感觉至关重要的转导离子通道。
