Final answer:
The response by receptors can be either graded potentials or action potentials, depending on the specific stimulus and receptor cell involved.
Step-by-step explanation:
Graded potentials can result from sensory stimuli, and the type of response by the receptors can be either graded potentials or action potentials, depending on the nature of the stimulus and the location of the receptor cells.
For example, in the skin, there are thermoreceptors that are sensitive to temperature. When these thermoreceptors receive a stimulus, such as hot water, the cell membrane of the thermoreceptors undergoes a graded potential, which is a temporary change in its electrical state. If the stimulus is strong, the graded potential can generate an electrical signal called an action potential, which travels along the axon for transmission to other cells.
Therefore, the response by receptors can be either graded potentials or action potentials, depending on the specific stimulus and receptor cell involved.
