Many vomeronasal neurons are activated by chemicals in urine. A multigene family encoding a diverse array of putative pheromone receptors in mammals. Sense Organs and Viscera". Sitting next to the lumen are blood vessels that dilate or constrict, forming a vascular pump that deliver stimuli to the lumen.

Notably, some scents act as chemical-communication signals pheromones from other individuals of the same species. Since the hypothalamus is a major neuroendocrine center affecting aspects of reproductive physiology and behavior as well as other functions such as body temperature , this may explain how scents influence aggressive and mating behavior. Cats have an additional scent organ, independent of their noses and totally lacking in humans.

Vomeronasal organ Frontal section of nasal cavities of a human embryo 28 mm. Keverne EB October The axons from these neurons project to the accessory olfactory bulb , which targets the amygdala and bed nucleus of the stria terminalis , which in turn project to the hypothalamus. Supreme superior middle inferior Sphenoethmoidal recess Ethmoid bulla Agger nasi Ethmoidal infundibulum Semilunar hiatus Maxillary hiatus. Air inhaled during flehmening brings the maximum number of scent particles into the vomeronasal organ. This allows each kitten to feed quickly without shoving and competing with siblings. Unlike the main olfactory bulb that sends neuronal signals to the olfactory cortex, the VNO sends neuronal signals to the accessory olfactory bulb and then to the amygdala , BNST , and ultimately hypothalamus.
