Definition

  • Olfaction is generally defined as the sensory system that allows an organism's nervous system to detect chemicals coming from a distant source. Senses that require contact with the chemical source, such as when we taste food on our tongue, are not considered olfaction; neither is the kind of chemoreception present in individual cells or in single-celled animals.
