What are the Two Basic Forms of Electrical Signals

Question

What are the two basic forms of electrical signals?
A)​high potentials and low potentials
B)physical and action potentials
C)graded potentials and action potentials
D)graded potentials and chemical potentials
E)​physical potentials and chemical potentials

Accepted Answer

The two basic forms of electrical signals in the nervous system are graded potentials and action potentials. Graded potentials are small changes in electrical potential that can either depolarize (excitatory) or hyperpolarize (inhibitory) a cell. Action potentials are brief, large changes in electrical potential that allow for long-range signaling and communication between neurons.
