ANATOMY

Detailed explanation-1: -Taste, also called gustation, and smell, also called olfaction, are the most interconnected senses in that both involve molecules of the stimulus entering the body and bonding to receptors.

Detailed explanation-2: -Receptor cells can be further categorized on the basis of the type of stimuli they transduce. Chemical stimuli can be interpreted by a chemoreceptor that interprets chemical stimuli, such as an object’s taste or smell. Osmoreceptors respond to solute concentrations of body fluids.

Detailed explanation-3: -There are two main classes of chemoreceptor: direct and distance. Examples of distance chemoreceptors are: olfactory receptor neurons in the olfactory system: Olfaction involves the ability to detect chemicals in the gaseous state. In vertebrates, the olfactory system detects odors and pheromones in the nasal cavity.

Detailed explanation-4: -Olfactory receptors allow the sense of smell. They are located at the back of the nasal cavity. They contribute to the sense of smell and taste.

Detailed explanation-5: -Sensory receptors that detect and respond to light, taste, and smell primarily belong to the G-protein-coupled receptor (GPCR) superfamily.
