Acetylcholine is released by preganglionic neurons (both sympathetic and parasympathetic) and by postganglionic neurons of the parasympathetic nervous system. The preganglionic release acts at nicotinic cholinergic receptors, and the postganglionic release acts at muscarinic cholinergic receptors.
- Sites of action: sympathetic ganglia, parasympathetic ganglia, adrenal medulla, parasympathetic postganglionic nerve terminal, neuromuscular junction, sweat glands.

-preganglionic neuron cell bodies are located in the brain (in motor nuclei of cranial nerves 3, 7, 9, and 10) and in the sacral part of the spinal cord
-preganglionic axons of the cranial part of the parasympathetic division leave the brain via cranial nerves 3, 7, 9, and 10.
-after synapsing within named autonomic ganglia in the cephalic region, parasympathetic fibers are distributed to salivary and lacrimal glands, smooth muscle of the eye, and to the smooth muscle and glands of the respiratory and digestive systems, and to the heart.
-preganglionic axons of the sacral part of the parasympathetic division synapse in ganglia located in the walls of the colon and urogenital organs.

sympathetic preganglionic neurons
-located in the T1 to L2 segments of the spinal cord (within the lateral gray column).
-located in sympathetic trunk ganglia as well as named ganglia primarily in neck, thorax, and abdomen.
-In general, sympathetic effectors are found throughout the body.
parasympathetic preganglionic neurons
-located in the brain (within motor nerve nuclei of cranial nerves 3, 7, 9, and 10) and in the sacral region of the spinal cord (in an area corresponding to the lateral gray column).
-located primarily in named ganglia in the head, in sacral region, and in terminal ganglia within walls of thoracic and abdominal organs.
-parasympathetic effectors are limited to the head and the viscera of the thorax, abdomen, and pelvis.

Through cranial nerves 3, 7, 9, 10, and through the sacral segments of the spinal cord. They synapse at autonomic ganglia in the head, thorax, abdomen, and pelvis (rarely at the sympathetic trunk ganglia). the postganglionic neurons are distributed to the heart as well as to smooth muscle and glands in the head, neck, thorax, and abdomen.

Where are preganglionic neurons of the autonomic nervous system are located?

The preganglionic neurons are located in specific cell groups (also called nuclei) in the brainstem or in the lateral horns of the spinal cord at sacral levels.

Where are the preganglionic neurons located quizlet?

Explanation: Cell bodies of the sympathetic preganglionic neurons are located in the lateral horn of the spinal cord gray matter between T1-L2.

What is a preganglionic neuron of the autonomic nervous system?

The sympathetic nervous system contains cell bodies that lie within the lateral gray column of the spinal cord running from T1 to L2. These neurons are known as preganglionic neurons and travel to ganglia, where they synapse and activate nicotinic receptors on postganglionic neurons using acetylcholine.

Where is the postganglionic neuron of the ANS located?

autonomic nervous system set, called ganglion cells or postganglionic neurons, lies outside the central nervous system in collections of nerve cells called autonomic ganglia.
