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. There is a pronounced interaction between our chemical senses.
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: -The other primary chemical sense, taste (technically, the gustatory system), responds to molecules dissolved in liquid. These molecules enter the system via taste buds: pear-shaped structures in which receptor-bearing cells surround a central pore. There are millions of receptors onsome 10, 000 taste buds.
Detailed explanation-4: -Chapter 15The Chemical Senses 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-5: -Taste (gustation) and smell (olfaction) are both chemical senses; that is, the stimuli for these senses are chemicals. The more complex sense is olfaction. Olfactory receptors are complex proteins called G protein-coupled receptors (GPCRs).
