There are five types of neurons and two types of neuroglia in PNS

Based on shapes, neurons are classified into five types namely Unipolar neurons, Bipolar neurons, Pseudounipolar neurons, Anaxonic neurons, and Multipolar neurons.

There are two types of neuroglia found within the peripheral nervous system:
Schwann cells – myelinate axons in the peripheral nervous system.
Satellite cells – regulate nutrient and neurotransmitter levels around neurons in ganglia.
