The mechanism of the olfactory system can be divided into a peripheral one, sensing an external stimulus and encoding it as an electric signal in neurons, and a central one, where all signals are integrated and processed in the central nervous system. The peripheral olfactory system receptors are connected to bipolar olfactory receptor neurons in the olfactory epithelium.
Fot the central olfactory system, axons from the olfactory sensory neurons converge in the olfactory bulb.
The olfactory system sends information directly to the olfactory bulb, which is located in the brain. From there, the information is processed in regions of the brain such as the olfactory cortex and limbic system, which are involved in processing smells and emotions.
Yes, humans have a vestigial accessory olfactory system, also known as the vomeronasal organ. While it is not functional in most adults, some studies suggest that it may still play a role in certain behaviors, such as social and reproductive interactions.

The olfactory system allows us to perceive and distinguish different scents, such as the aroma of fresh flowers in the garden.

enhancing discrimination between odors.enhancing sensitivity of odor detection.filtering out many background odors to enhance the transmission of a few select odors.permitting higher brain areas involved in arousal and attention to modify the detection or the discrimination of odors.Olfactory nerves act as transducers - changing chemical signals, as when an odor chemical binds to its receptor at an olfactory dendritic nerve ending, into nerve impulses - that is (i.e.) biological signals. These reside in the mucous membrane.Nerve fibers leave the olfactory cells and enter the skull through the ethmoid bone, then disappear into the 'olfactory bulb' located at the anterior end of the 'olfactory tract', which then leads to the frontal - and eventually the temporal - lobe of the cerebrum.

olfactory |älˈfakt(ə)rē; ōl-|adjectiveof or relating to the sense of smell : the olfactory organs.It is an adjective so it is used to describe anything that has to do with the sense of smell.ex. Reptiles have two distinct olfactory systems - the main olfactory system, and the accessory olfactory system.orAs of now, there is no theory that explains olfactory perception completely.
