Olfaction:Olfaction refers to the sense of smell, where specialized receptors in our nose detect chemical molecules carried by airborne particles.
Gustation:Gustation is the sense of taste, where receptors on our tongue detect chemical molecules dissolved in saliva.
Chemoreceptors: Chemoreceptors are sensory cells that respond to chemical stimuli and are responsible for detecting airborne particles for both olfaction and gustation.
