Dorsal root ganglion



Dorsal root ganglia (DRG) is "a nodule in a dorsal root that contains cell bodies of neurons in afferent spinal nerves." They lie along 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."

The neuron is parted of two parts:


 * 1) Dendrite that receives the information and sends it to the Perykaron (cytoplasm which is around the nucleus)
 * 2) Axon takes this information and sends forward



Dorsal root ganglia in ME/CFS
Inflammation of the DRG has been found in the autopsies of several very severely ill Myalgic encephalomyelitis patients including Lynn Gilderdale, Sophia Mirza and Merryn Crofts.
