Question

Quizplus · Accepted Answer

The vomeronasal organ is a specialized sense organ that is responsible for detecting pheromones, which are chemical signals used for communication between members of the same species. While it is present in many different species, including humans, its importance in human behavior is still debated. However, in animals such as dolphins, it has been shown to be critical for sexual behavior. The organ is not heavily innervated by neurons, and it does not project to the primary visual cortex.
