Glial cells in the peripheral nervous system (PNS) play vital supportive roles, encasing neurons to provide insulation, metabolic aid, and protection, distinct from their CNS counterparts. This diagram focuses on a unipolar peripheral ganglionic neuron, illustrating how satellite cells and Schwann cells interact with the cell body and axon, ensuring efficient signal transmission and repair in sensory and autonomic pathways. These cells highlight the PNS's regenerative capacity, contrasting with the CNS, and underscore their importance in maintaining neural integrity across nerves extending from the spinal cord and brain to peripheral tissues.
