Why does the frog sciatic nerve give a graded response?

1 answer:

8 0

The sciatic nerve of the frog is constituted of a bundle of nerve fibers. Each of the nerve fiber has a varying threshold for which the membrane potential is disturbed. This is the reason why graded potential is observed as each nerve fiber depolarizes until a threshold in the sciatic nerve ( following summation of all individual depolarization events) is reached to trigger an action potential.
