Question

what is all and none law?

Answer 1

Heyya!

All or none law is applicable to nerve fibres and it means that a stimulus should be strong enough for the response to occur. If the stimulus is less than the threshold then the process would not be started at all but if the stimulus is even slightly greater than the threshold then complete response would be shown. In other words the response is not dependent on the strength of the stimulus. According to this law the nerve fibre would either give a complete response or no response at all.

Hope it helps! : )

here is your answer
=================
The all or none law refers to how your nerve cells function - they either respond to a stimulus completely or not at all; there is no in between
