The sympathetic ganglia lie close to the vertebral bodies and are also known as paravertebral ganglia. They are strung together to form a sympathetic or paravertebral chain. There are two of these chains, one on either side of the vertebral column connected in front of the coccyx by the single ganglion impar (Fig-2).
Ganglionic Blockers. Autonomic Ganglia. Sympathetic autonomic ganglia are comprised of the paravertebral ganglia (sympathetic chain ganglia) and the prevertebral ganglia. Preganglionic sympathetic fibers that exit the spinal cord synapse within these ganglia and release the neurotransmitter acetylcholine (ACh), which binds to nicotinic receptors. Activation of the nicotinic receptors depolarizes the cell body of the postganglionic neuron and generates action potentials that travel to the target organ to elicit a response. Parasympathetic autonomic ganglia are found within the target organ.
