Question
Chapter 41.3, Problem 2C
Summary Introduction
To describe: The sequence of events that occur when a neuron attains threshold level.
Introduction: Neurons are the basic unit of the nervous system. Their main function is to “receive and transmit” the information. Threshold level is defined as the critical point where a change in membrane potential occurs due to a shift in electrical charges.
