Definitions:

Presynaptic Facilitation

An increase in the neurotransmitter release from a presynaptic neuron, enhancing the response of the postsynaptic neuron.

Myelinated Fiber

A nerve fiber with a myelin sheath, which increases the speed at which electrical impulses propagate along the nerve fiber.

Initial Segment

The first portion of a nerve cell axon nearest to the cell body, critical for the initiation of neural signals.

Voltage-Regulated Channels

Ion channels in the cell membranes that open or close in response to changes in membrane potential, crucial for the transmission of electrical signals.
