Question

The stronger the stimulus applied to a receptor ending:

1. The larger the number of ion channels opened in the re-membrane
2. The larger the magnitude of the re-membrane depolarization
3. The larger the frequency pf action potentials generated in the receptor axon
4. The greater the amplitude of the action potential
5. Greater pain will be perceived by the brain, due to maximal frequency of action potentials

1. 1,2,3,5
2. 1
3. 1,3
4. 1,2,3,4

Answer 1

Answer is D. - 1,2,3,4

The stronger the stimulus applied to a receptor ending:

The larger the frequency pf action potentials generated in the receptor axon- the size of action potential does not. Increase with increase in intensity of stimulus rather the frequency or number of action potential increase which leads to

1. The larger the number of ion channels opened in the re-membrane causing
2. Thel arger the magnitude of the re-membrane depolarization...

Finally ,

1. The greater the amplitude of the action potential Greater pain will be perceived by the brain, due to maximal frequency of action potentials
