Definitions:

Unmyelinated

refers to nerve fibers that lack a myelin sheath, resulting in slower signal transmission compared to myelinated fibers.

Axon Diameter

Refers to the width of an axon, which influences the speed of nerve impulse conduction, with larger diameters allowing faster conduction.

Neurotransmitters

Chemicals that transmit signals across a synapse from one neuron to another in the nervous system.

Retrograde Signals

Molecular signals that travel from the postsynaptic neuron back to the presynaptic neuron, modulating neurotransmission.
