Question

Quizplus · Accepted Answer

Sensory receptors are activated by a stimulus, which can be in the form of light, sound, touch, taste, or smell. This stimulus triggers a response in the sensory receptor, leading to the generation of a nerve impulse that travels to the brain. Graded potentials and action potentials are both types of electrical signals within the body, but they are not the specific trigger for sensory receptors. Multiple occurrences of the same event may increase the strength of the stimulus, but they are not necessary for activation of the receptor.
