It provides insulation to the axons and dendrites during depolarization or action potential.
if the graded potential of threshold size reaches a trigger zone
Hyperpolarization of the membrane. This inhibits action potential generation.

Depolarization is a change in a cell's membrane potential, making it more positive, or less negative. In neurons and some other cells, a large enough depolarization may result in an action potential.
A synaptic potential exists at the INPUT of a neuron (dendrite), and an action potential occurs at the OUTPUT of a neuron (axon). (from OldGuy)(from Ilantoren:) A synaptic potential is the result of many excitatory post synaptic potentials (epsp) each one caused by the synaptic vesicles released by the pre-synaptic terminus. If there are enough of these epsp then the responses will summate and depolarize the post-synaptic membrane at the axon hillock enough to fire an action potential.
Reflex action
They are the same as they are anywhere else in the English language. Cause means why something happens. Action is what happens. Result is the end or consequences of that action.

The effect the result of what happens after a action or cause. It is also called a consequence or outcome.
Depolarization is a change in a cell's membrane potential, making it more positive, or less negative. In neurons and some other cells, a large enough depolarization may result in an action potential.

Organic matter in a compost bin decomposes as a result of bacteria action.

Consequence - A result or effect that is caused by a specific action or decision made by a person.
