Explain the Differences Between Types of Graded Potentials
And explain the difference between an EPSP and an IPSP. Graded potentials can be of two sorts either they are depolarizing or hyperpolarizing Figure 1. Presynaptic And Postsynaptic Cell Google Search Biology Physiology Brain Anatomy And Function Action potential AP or impulse. . Graded potentials travel over short distances and are activated by the opening of mechanically or chemically gated channels. First some new terminology. Graded potentials can be of two sorts either they are depolarizing or hyperpolarizing. For a membrane at the resting potential a graded potential represents a change in that voltage either above -70 mV or below -70 mV. The graded potentials are small changes in the membrane potential that can reinforce or negate each other. Explain the difference between graded potentials and action potentials. End plate potentials EPPs occur in muscle cells result from the activation of ligand-gat...
