The sympathetic efferents have a thoracolumbar outflow from spinal roots T1-L2 (Fig 1).

Question: Where are preganglionic cell bodies found?

Answer

The sympathetic efferents have a thoracolumbar outflow from spinal roots T1-L2 (Fig 1).

Question: Where are preganglionic cell bodies found?

Answer: Preganglionic cell bodies are found in the lateral horns of the spinal cord, and their axons can terminate in one of three ways:

Question: Where are preganglionic cell bodies found?

Answer: Preganglionic cell bodies are found in the lateral horns of the spinal cord, and their axons can terminate in one of three ways:

1. Most synapse in the paravertebral sympathetic chain: a series of sympathetic ganglia found alongside the vertebral column from the base of the skull to the coccyx

Question: Where are preganglionic cell bodies found?

Answer: Preganglionic cell bodies are found in the lateral horns of the spinal cord, and their axons can terminate in one of three ways:

1. Most synapse in the paravertebral sympathetic chain: a series of sympathetic ganglia found alongside the vertebral column from the base of the skull to the coccyx
2. Some pass through the sympathetic chain, via the splanchnic nerves, to synapse in a peripheral autonomic ganglion in the abdomen or pelvis, e.g. the coeliac ganglion, superior mesenteric ganglion or inferior mesenteric ganglia

3. A few preganglionic fibres synapse directly with chromaffin cells in the medulla of the adrenal gland
