Answer :
Olfactory receptor cells are actually neurons that contain pseudostratified columnar epithelial cells with olfactory hairs on their apical ends.
Olfactory receptor, often known as the "smell receptor," is a protein that can bind odour molecules and is essential for the perception of smell (olfaction). These receptors are shared by fish, terrestrial vertebrates, arthropods, and other animals.
One of the first senses in terms of evolution is smell, which enables species with odorant receptors to recognise food, possible mates, threats, and foes. One of the most crucial senses for interacting with the environment is smell, both for most living things and for humans.
Neurons are the fundamental constituents of the brain and nervous system (also known as neurones or nerve cells). In addition to receiving sensory information from the outside world, controlling our muscles, and converting and relaying electrical impulses at various points along the way, neurons are also in charge of receiving sensory information from inside our bodies.
