What sensory receptors are triggered by chemical substances?

• A. Receptors for taste and smell
• B. Rods and cones
• C. Auditory receptors
• D. Hair cells

Answer: (A)

Verified step by step guidance

1. Identify the sensory systems involved in detecting chemical substances. In psychology, these are primarily the gustatory (taste) and olfactory (smell) systems.
2. Understand that the gustatory system involves taste receptors located on the tongue, which are activated by chemical substances in food and drink.
3. Recognize that the olfactory system involves smell receptors located in the nasal cavity, which are triggered by airborne chemical substances.
4. Differentiate these chemical receptors from other types of sensory receptors, such as rods and cones in the visual system, which detect light, and auditory receptors, which detect sound.
5. Conclude that the sensory receptors specifically triggered by chemical substances are the receptors for taste and smell, as they are designed to respond to chemical stimuli.
