Definition
-
An accessory chemoreceptor organ that is separated from the main olfactory mucosa. It is situated at the base of nasal septum close to the vomer and nasal bones. It forwards chemical signals (such as pheromones) to the central nervous system, thus influencing reproductive and social behavior. In humans, most of its structures except the vomeronasal duct undergo regression after birth.
