AP PSYCHOLOGY

Detailed explanation-1: -Taste (gustation) and smell (olfaction) are called chemical senses because both have sensory receptors that respond to molecules in the food we eat or in the air we breathe.

Detailed explanation-2: -Smell = Olfaction-olfactory system Taste = Gustation-gustatory system-called “chemical” senses because their function is to monitor the chemical content of the environment.

Detailed explanation-3: -Overview. Three sensory systems associated with the nose and mouth-olfaction, taste, and the trigeminal chemosensory system-are dedicated to the detection of chemicals in the environment.

Detailed explanation-4: -The external chemical senses are usually divided into taste, or gustation (for dissolved chemicals that inform about the palatability of food), and smell, or olfaction (for airborne chemicals that inform about events at a distance).

Detailed explanation-5: -Taste, or gustation, is mediated by receptors that respond to chemical stimulation on the dorsum of the tongue and in parts of the larynx, pharynx and epiglottis.
