Question
Chapter 11.5, Problem 31AYP
Summary Introduction
To describe:
The concept of graded potential and the events that can cause it along with the definition of decremental conduction of graded potentials.
Introduction:
An action potential has four phases. These are a depolarization phase, a repolarization phase, an afterpotential, and the resting membrane potential.

What is a graded potential, and what four events cancause it? Define decremental conduction of gradedpotentials
What is a graded potential? Where does a graded potential start in a neuron? Do graded
potentials always result in an action potential? Are all graded potentials depolarizing?
Why or why not? Where are action potentials started in a neuron and what is the
threshold potential to do so in a neuron?
What determines the size of a graded potential?
