Chapter 10, Problem 1E
Summary Introduction

Introduction :

The stimuli can be defined as the external changes, which can trigger a physiological response in the body of an organism. If the stimuli are strong enough to make the changes to a threshold potential, then it can trigger a neural response to it.

Expert Solution & Answer

Answer to Problem 1E

The correct answer is option (d).

Explanation of Solution

Explanation for the correct answer:

Option (a) the size of the receptor potential. The size of the receptor potential must be enough to reach the threshold and the size also determines the intesity of sensation.

Option (c) the frequency of the action potential. The frequency of the action potential can describe the frequency of the stimulus and the receptor potential. More the frequency of action potential, more will the intensity of the stimulus.

Option (d) (a) and (c). As the size of the receptor potential and the frequency of the action potential both determines the strength of the stimulus, the option (a) and (c) both are true. So, the correct answer is option (d).

Explanation for the incorrect answer:

Option (b) size of the action potential. The size of the action potential does not determine the strength of the stimulus. Once the potential is able to reach the threshold, it generates a neural response. Hence, it is an incorrect answer.

Option (e) is given as all of the above. As option (c) is incorrect, this option is also incorrect.

Conclusion

The size of the receptor potential and the frequency of the action potential both determines the strength of the stimulus. Hence, the correct answer is option (d).
