Question

Quizplus · Accepted Answer

Whether or not humans have a separate vomeronasal sense remains a topic of debate among researchers. Some studies suggest that the vomeronasal organ is vestigial in humans and no longer functional, while others indicate that it may still play a role in human social and sexual behavior.

Answer: None of the above
 None of the statements presented are entirely accurate. The human olfactory bulb is located at the base of the brain, not above the occipital lobe. While pheromones do play a role in human sexual behavior, there is limited evidence to suggest that tears specifically increase male sexual response. Most humans do not have functional vomeronasal organs, and those who do have them in the nasal cavity rather than the roof of the mouth.
