Question

Q4.2. What information does the pain receptor relay to the brain about stimuli BELOW threshold? O The duration of the stimulation O The location of the stimulation O The membrane potential at the site of stimulation O None of the above Q4.3. After the rising phase, which ion channel is responsible for action potential returning to its resting Vm, and why? O Na* channels, because positive Nat ions are at higher concentration outside the axon than inside, and so they enter the axon and raise Vm Na* channels, because positive Na ions are at higher concentration inside the axon than outside, and so they leave the axon and raise Vm so they enter the axon and raise V so they leave the axon and lower Vm K* channels, because positive K ions are at higher concentration outside the axon than inside, and K* channels, because positive K* ions are at higher concentration inside the axon than outside, and

Explanation / Answer

Ans

In our body all information are transmitted to brain in form of action potential if we talk about pain receptor, then it need to get threshold potential to be feel in brain otherwise not.

Answer is none of above

Ans-2

After rising phase potassium channel open so potassium ion move from interior of the cell to outside due to gradient , which cause initially hyperpolarization but later it get back to resting membrane potential.
