Preganglionic neuron - from spinal cord (or brain) to the autonomic ganglion. 2. All Parasympathetic postganglionic fibers release Acetylcholine.

Postganglionic fibers of the sympathetic division mainly release norepinephrine whereas postganglionic parasympathetic fibers release acetylcholine. An exception to this rule is the postganglionic sympathetic fibers to sweat glands, which release acetylcholine .

D)has its axons exiting the CNS through cranial nerves. E)carries information into the sympathetic chain ganglia. The postganglionic parasympathetic nerves also release acetylcholine, and the postsynaptic target cells have muscarinic cholinergic receptors.

20 May 2011 Acetylcholine (ACh) is the main parasympathetic, postganglionic neurotransmitter, but it also is released in all preganglionic neurons, both 

Effects of acetylcholine release on target organs include slowing of heart rate, lowered blood pressure, and stimulation of digestion. Preganglionic neurons release acetylcholine (ACh) onto nicotinic receptors on the postganglionic neuron. Nicotine, found in tobacco products, also binds to and activates nicotinic receptors, mimicking the effects of ACh. Both sympathetic and parasympathetic preganglionic neurons are cholinergic, meaning they release acetylcholine (Ach) at the synapse in the ganglion. In the parasympathetic system, postganglionic neurons are also cholinergic. However in the sympathetic system, postganglionic are not all the same.

The chromaffin cells of the adrenal medulla are analogous to post-ganglionic neurons—the adrenal medulla develops in tandem with the sympathetic nervous system and acts as a modified sympathetic ganglion. However, there are three important exceptions: Postganglionic neurons of sweat glands release acetylcholine for the activation of muscarinic receptors, except for Chromaffin cells of the adrenal medulla are analogous to post-ganglionic neurons; the adrenal medulla develops in tandem Postganglionic neurons of the autonomic system are classified as either cholinergic, meaning that acetylcholine (ACh) is released, or adrenergic, meaning that norepinephrine is released. Postganglionic neuron where acetylcholine (ACh) is released that stimulates nicotinic receptors and muscarinic receptors.

An exception to this rule is postganglionic fibers that release acetylcholine onto muscrinic receptors in the sweat glands.

78) When acetylcholine binds to [dropdown 1] receptors on postganglionic neurons or chromaffin cells it is always [dropdown 2]. Dropdown 1 choices: a)muscarinic receptors Diminished release of acetylcholine from preganglionic sympathetic neurons would: A) increase the activity of postganglionic sympathetic neurons. B) reduce the activity of postganglionic sympathetic neurons.

A) It inhibits acetylcholine release from motor neurons. B) It blocks nicotinic cholinergic receptors. C) It stimulates acetylcholine release from autonomic preganglionic neurons. D) It inhibits the degradation of acetylcholine at all synapses. E) It stimulates acetylcholine release from motor neurons.

The postganglionic neurons of sweat glands release acetylcholine for the activation of muscarinic receptors. The chromaffin cells of the adrenal medulla are analogous to post-ganglionic neurons—the adrenal medulla develops in tandem with the sympathetic nervous system and acts as a modified sympathetic ganglion. In contrast, postganglionic sympathetic fibers release norepinephrine onto cells that have α 1-, α 2-, β 1-, or β 2-receptors. An exception to this rule is postganglionic fibers that release acetylcholine onto muscrinic receptors in the sweat glands. For comparison, a somatic α-motor neuron that controls skeletal muscle is also shown. Both sympathetic and parasympathetic preganglionic neurons are cholinergic, meaning they release acetylcholine (Ach) at the synapse in the ganglion.

acetylcholine : norepinephrine. The Correct Answer is. Parasympathetic postganglionic neurons release the neurotransmitter _____; sympathetic postganglionic neurons release the neurotransmitter _____. Reason Explained

For comparison, a somatic α-motor neuron that controls skeletal muscle is also shown. The neurotransmitters of postganglionic fibers differ: In the parasympathetic division, neurons are cholinergic. That is to say acetylcholine is the primary neurotransmitter responsible for the communication between neurons on the parasympathetic pathway. The acetylcholine activates the postganglionic neurons. Postganglionic neurons then release norepinephrine onto target organs.

And most postganglionic neurons release the neurotransmitters adrenaline and noradrenaline, collectively called catecholamines. These catecholamines bind to adrenergic receptors on the Both sympathetic and parasympathetic preganglionic neurons are cholinergic, meaning they release acetylcholine (Ach) at the synapse in the ganglion. In the parasympathetic system, postganglionic neurons are also cholinergic.
