Primary detection of odorants in the vomeronasal system occurs in the vomeronasal organ. |
In all squamates, including iguanians, the tongue is also used for vomeronasal chemoreception. |
In addition, the vomeronasal organ in the nose is a part of a chemosensory system that is independent of the olfactory system. |
The results do not apply to humans since we do not have vomeronasal organs. |
Both the primary olfactory system using the olfactory bulbs, and the secondary olfactory system using the vomeronasal organ are used. |
As in snakes and many mammals, all lizards have a specialised olfactory system, the vomeronasal organ, used to detect pheromones. |
