Nasal Reflexes

Abstract
Nasal reflexes are neurally mediated reactions which arise either through direct stimulation of the nasal mucosa or through stimulation of pathways elsewhere in the body which indirectly involve the nose. The neural pathways involved in these reactions are complex, and the exact nature of the stimuli which trigger these reflexes has not been completely detailed. This review presents a discussion on the innervation of the nose, updates the current understanding about nasal neuropeptides, and then summarizes information about several different types of nasal reflexes.
