Define olfactory receptor
WebThe meaning of OLFACTORY CELL is a sensory cell specialized for the reception of sensory stimuli caused by odors; specifically : any of the spindle-shaped neurons that … WebIn this region, millions of olfactory sensory neurons (OSNs) interact with odor molecules through the odorant receptors (ORs), which belong to the superfamily of G protein-coupled receptors. The binding of odors to the ORs initiates an electrical signal that travels along the axons to the main olfactory bulb of the brain.
