The olfactory tract guides airborne particles to the olfactory bulb. The sensory fabric includes olfactory glands that probably signal depending on the particle’s shape and electrochemical structure. Odorant molecules are brought in mucus into close contact with the olfactory epithelium. This fabric is host to olfactory receptor cells, supporting cells, basal stem cells, and olfactory glands.

Smell or olfaction is one of the two main "chemical" senses. is the other "chemical" sense. Unlike taste, there are hundreds of olfactory receptors (388 according to one source), each binding to a particular molecular feature.
