The cell bodies of sensory neurons associated with spinal nerves are located in clusters known as dorsal root ganglia (also referred to as spinal ganglia).123

These ganglia are oval-shaped swellings situated on the dorsal roots of the spinal nerves, positioned within openings in the vertebral column called the intervertebral foramina. Unlike motor neuron cell bodies, which are found within the gray matter of the spinal cord itself, these sensory cell bodies reside outside the central nervous system. Each sensory neuron in these ganglia is typically unipolar, featuring a single fiber that bifurcates in a T-shape to connect peripheral receptors with the central nervous system.45316
