Summary Introduction

To explain:

The decremental spread of graded potential.

Introduction:

Graded potentials are local changes in the membrane potential in different levels or degrees of force or magnitude. The graded potential is generated by a specific trigger event which leads to the opening of the gated ion channels in an excitable cell membrane region. The resulting ion movement creates the graded potentials which most often results in depolarization from net Na⁺. The graded potential of the plasma membrane is restricted to this small, specialized area.
