Describe the origin and pathway of an impulse that results in smell?
Wiki User

Smell is a chemical sense detected by sensory cells called chemoreceptors. When an odorant stimulates the chemoreceptors in the nose that detect smell, they pass on electrical impulses to the brain which then interprets patterns in electrical activity as specific odors and olfactory sensation becomes perception.

When you smell something, chemicals in the air enter your nose and stimulate specialized sensory cells in the olfactory epithelium. These cells then send signals through the olfactory nerve to the olfactory bulb in the brain. The olfactory bulb processes these signals and sends them to higher brain regions for further interpretation, resulting in your perception of smell.
