21. Naphthalene interferes with the vomeronasal organ of snakes, thereby disrupting their olfactory system in a reversible manner. 22. The vomeronasal organ of birds is either under-developed or altogether absent, depending on the species. 23. This suggests that the vomeronasal organ plays an active role in maternal identification of the lamb at the udder 24. This experiment found that vomeronasal -lesioned animals showed little difference from controls in both responsiveness and selectivity. 25. Thus, the chemical messages are detected by the vomeronasal gland inside the nasal passages of those around you. 26. Dulac's findings are based on tests with a mouse breed whose vomeronasal organ had been genetically inactivated. 27. They smell by using their forked tongues to collect airborne particles, then passing them to the vomeronasal organ. 28. One group was allowed to sniff synthesized pheromones that are said to act on the vomeronasal organ in the nose. 29. The second, located under the nasal cavity, are the Vomeronasal organs, also called Jacobson's organs. 30. The importance of the vomeronasal system to the role of reproduction and social networking has been shown in many studies.
