Definitions:

Nodes Of Ranvier

Gaps in the myelin sheath of axons that facilitate rapid signal transmission via saltatory conduction.

Hyperpolarization

A change in a cell's membrane potential, making it more negative, and thus further from initiating an action potential.

Inhibitory Postsynaptic Potential

A type of synaptic potential that makes a post-synaptic neuron less likely to generate an action potential, usually by making the inside of the neuron more negative.

Neuronal Membrane

The lipid bilayer that encases neurons, regulating the entry and exit of substances and maintaining the electric potential used for neural transmission.
