What is an absolute refractory period for action potential a

Solution

Absolute refractory period refers to a phase when the nerve fibre is incapable of repeating the action, it can be described as a phase inwhich the fibre prepares itself for the next stimulus.

Absolute refractory periods are important because it helps to keep the action potential moving in single direction through axons.

It also keeps the maximum firing frequency if neuron in check
