The olfactory membrane is a layer of cells on the roof of the nasal cavity also called theepithelium, . It is made up of three layers, the supporting cells, the olfactory receptor cells, and the basal cells. Supporting cells help produce mucus. Basal cells are the source of new receptors. and Olfactory receptor cells, these are actually neurons and are the site of transduction. Olfactory receptor cells are the only neurons in the nervous system that are regularly replaced, lasting about about 4 to 8 weeks.
Olfactory nerves, definetly. We're studying this currently in my grade.
The nose is the sense organ that has olfactory cells responsible for detecting an odor. These cells are located in the nasal cavity and respond to the molecules in the air that we inhale.

A specialized smell receptor is situated In the roof of the nasal canal,called Olfactory mucosa. the olfactory epithelium is innervated by the olfactory(1st cranial)nerve and some branches of the 5th nerve.Olfactory epithelium contains three kinds of cells,namely olfactory receptor cells,supporting cells and basal cells.Olfactory receptor cells are sensory hair cells,sensitive to all kind of cells.Their axons terminally join the olfactory nerve. Supporting cells are mucus-secreting columnar cells. Basal cells are the stem cells from which new receptor cells are formed.Olfaction,just like taste,is a chemical sense. The molecules of the odorous substances reach the nasal canal along with the inspired air. Here, they dissolve in the mucus secretion and then attach to the receptor cells. This stimulates the receptor cells and they generate olfactory impulses. Olfactory nerves transmit these impulses to the olfactory center in the temporal lobe of the cerebrum(known as the olfactory cortex)

The receptors that actually bind with the molecules that we smell are called Olfactory receptor neurons. They pass their signal through the caribform plate, then down the olfactory nerve, and finally to the olfactory bulb in the brain.

The word olfactory or olfactory system deals with the sense of smell. One can sense smells or scents through the nose. To find out more about the word "olfactory" it is recommended to look it up in the dictionary.
Smelling sense.
The cells responsible for our sense of smell are called neurons, specifically olfactory receptor neurons. They are linked directly to the brain, and respond to different chemical signals to generate what we then perceive as smells and odors.
