Detailed explanation-1: -Jacobson’s organ, also called vomeronasal organ, an organ of chemoreception that is part of the olfactory system of amphibians, reptiles, and mammals, although it does not occur in all tetrapod groups. It is a patch of sensory cells within the main nasal chamber that detects heavy moisture-borne odour particles.

Detailed explanation-2: -This organ is present in all snakes and lizards. It is also present in mammals such as dogs and cats. This organ is present in human beings also, but it is vestigial and non-functional in nature.
