Preganglionic neurons synapse with postganglionic neurons in the autonomic nervous system. These synapses occur in ganglia, which are clusters of nerve cell bodies located outside the central nervous system. In the sympathetic division, preganglionic neurons typically synapse in sympathetic ganglia near the spinal cord, while in the parasympathetic division, they synapse in ganglia located close to or within the target organs. This synaptic connection is crucial for transmitting signals that regulate involuntary bodily functions.
Preganglionic neurons develop from the neural tube during embryonic development. They are part of the autonomic nervous system and transmit signals from the central nervous system to the autonomic ganglia, where they synapse with postganglionic neurons.
The preganglionic fibers of the autonomic nervous system travel through the cranial nerves (in the head) and the spinal nerves (in the rest of the body). They synapse with postganglionic neurons in autonomic ganglia before reaching their target organs.
A synapse is the junction or a point of close contact between two neurons.
Preganglionic fibers of the parasympathetic division of the autonomic nervous system synapse with postganglionic neurons in the ganglia located near or within their target organs. This allows for the transmission of nerve impulses from the central nervous system to the specific organs to regulate functions like digestion, salivation, and smooth muscle contraction.
The thoracic region of the spinal cord lacks autonomic preganglionic neurons. Autonomic preganglionic neurons are found in the intermediolateral cell columns of the spinal cord at the thoracolumbar (T1-L2) and sacral (S2-S4) levels.

Preganglionic sympathetic fibers trigger the release of acetylcholine at the synapse with postganglionic neurons in the sympathetic ganglia. This neurotransmitter binds to nicotinic acetylcholine receptors on the postganglionic neuron, which then propagate the signal to release norepinephrine at the target tissue.

Preganglionic fibers of the autonomic nervous system typically run from the central nervous system to an autonomic ganglion outside the central nervous system, where they synapse with postganglionic neurons. These fibers are part of the efferent pathway that transmits signals from the central nervous system to the peripheral organs and tissues.
synapse is that junction through which impulse can be transmitted from one neuron to another.
