Does the sympathetic division secrete norepinephrine?
Yes, when stimulated the sympathetic postganglionic fibers release norepinepherine (20%) and epinepherine (80%).
Does parasympathetic have postganglionic axons secrete norepinephrine?
no, not all postganglionic sympathetic fibre neuron secrete NE
What sympathetic ganglion distributes postganglionic neuronal processes to the kidneys?
aorticorenal ganglion
Do the sympathetic fibers leave the CNS at the thoracolumbar region?
All preganglionic sympathetic fibers leave the CNS at the thoracolumbar region, yes.
What is the sympathetic ganglion that distributes postganglionic neuron processes to the kidneys and gonads?
The sympathetic ganglion that distributes postganglionic neuron processes to the kidneys and gonads is the prevertebral ganglion called the superior mesenteric ganglion. It is located in the abdominal cavity, anterior to the aorta and just below the origin of the superior mesenteric artery.
What releases catecholamines as a neurotransmitter?
it would be postganglionic sympathetic fibers
Which division of the autonomic nervous system is characterized by short preganglionic and long postganglionic fibers?
The parasympathetic nervous system has long preganglionic and short postganglionic fibers
Does the sympathetic division secrete norepinephrine?
Yes, when stimulated the sympathetic postganglionic fibers release norepinepherine (20%) and epinepherine (80%).
The postganglionic sympathetic fiber originates from?
The postganglionic sympathetic fiber originates from PNS within a ganglion
Postganglionic fibers that innervate targets in the body wall or thoracic cavity originate on neurons within?
sympathetic chain ganglia
How would a drug that stimulates acetylcholine receptors affect the sympathetic nervous system?
Preganglionic fibers for the SNS release ACh; so a drug that stimulates ACh receptors would stimulate the postganglionic fibers of sypathetic nerves, resulting in increased sympathetic activity
Do all visceral motor neurons synapse in a sympathetic ganglion?
No; some axons synapse in nearby autonomic ganglion. postganglionic fibers travel along either sympathetic nerves or rejoin at the spinal nerve.
Does parasympathetic have postganglionic axons secrete norepinephrine?
no, not all postganglionic sympathetic fibre neuron secrete NE
Does the white rami communicans contain fibers of a preganglionic or postganglionic neurons?
Preganglionic because they are myelinated. FALSE
What has short unmyelinated postganglionic fibers?
parasynpathetic system
What is innervated by postganglionic fibers arising from the cervical ganglia?
the eyes
Postganglionic axons secrete acetylcholine cholinergic fibers?
Parasympathetic
