The dorsal root ganglion is a key structure in the peripheral nervous system, housing the cell bodies of sensory neurons that relay critical information from the body to the spinal cord. This photomicrograph provides a detailed view of its cellular organization, showcasing unipolar neurons and their axons, which form part of the dorsal nerve root. Exploring this anatomy offers a deeper understanding of sensory processing and the intricate network that supports bodily sensation.

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.
