Question
The central nervous system interprets the strength of a stimulus based on which of the following?Multiple choice question.The amount of open gated ion channels in a sensory cellThe size of the receptor potential in sensory cellsThe frequency of action potential generated by sensory cells
Solution
The central nervous system interprets the strength of a stimulus based on:
-
The amount of open gated ion channels in a sensory cell: This is not the primary method for interpreting the strength of a stimulus. While the number of open gated ion channels can influence the strength of the signal sent to the CNS, it is not the main factor the CNS uses to interpret the strength of a stimulus.
-
The size of the receptor potential in sensory cells: This is also not the primary method for interpreting the strength of a stimulus. The size of the receptor potential can influence the strength of the signal sent to the CNS, but it is not the main factor the CNS uses to interpret the strength of a stimulus.
-
The frequency of action potential generated by sensory cells: This is the primary method the CNS uses to interpret the strength of a stimulus. The more frequently action potentials are generated, the stronger the CNS interprets the stimulus to be. Therefore, the correct answer is "The frequency of action potential generated by sensory cells".
