Dorsal root ganglion
Dorsal root ganglia (DRG) is "a nodule in a dorsal root that contains cell bodies of neurons in afferent spinal nerves."[1] They lie along the posterior of the vertebral column by the spine. The dorsal root ganglia "contain the cell bodies of afferent nerve fibres (those carrying impulses toward the central nervous system); efferent neurons (carrying motor impulses away from the central nervous system) are present in the ventral root ganglia."[2]
The neuron is parted of two parts:
- Dendrite[3] receives the information and sends it to the Perykaron (cytoplasm which is around the nucleus).
- Axon[4] takes this information and sends forward.
In human disease[edit | edit source]
Ganglionitis is inflammation of a nerve ganglion. The dorsal root ganglia can become inflamed causing severe pain and other symptoms. Conditions that can cause dorsa root ganglionitis include trauma, sciatica, compressive neuropathy, herniated disc, spinal stenosis, peripheral neuropathy, meningitis, and spinal infections[5][6], including Herpes simplex virus 1.[7]
ME/CFS[edit | edit source]
Inflammation of the dorsal root ganglia (ganglionitis) has been found in the autopsies of several very severely ill myalgic encephalomyelitis patients including Lynn Gilderdale, Sophia Mirza and Merryn Crofts.[citation needed][8][9][10]
Sjogren’s syndrome[edit | edit source]
13 Sjogren’s patients with autonomic dysfunction were found to have lymphocytic (T‐cell) infiltration in the dorsal roots and ganglia, Electrophysical studies also found involvement of the dorsal root ganglia.[11] Antiganglion autoantibodies have been detected in patients with sensory neuropathy.[11]
