Upper-nose olfactory-cleft mucus cells {olfactory epithelium} {orthonasal olfactory system} are olfactory receptors, basal cells, and supporting cells. In mammals, odor receptors are at nose air-passage top or back. In humans, smell regions are four square-centimeters. Olfactory epithelium is mostly small sensory cells {olfactory sensory neuron} (OSN), with cilia that have odor receptors.
Olfactory region is light yellow in humans and dark yellow or brown in animals. Albinos have white regions and typically have poor smell ability.
