Autonomics Chart Flashcards
What is the sympathetic division also known as?
Tharacolumbar
What is the parasympathetic division also known as?
Craniosacral
What is the function of the sympathetic system?
Fight or flight response
Which system has longer preganglionic fibers?
Parasympathetic
Which system system has longer postganglionic fibers?
Sympathetic
What are the pre ganglionic NTs for the sympathetic division?
ACh
What are the pre ganglionic NTs for the parasympathetic division?
ACh
What is the postganglionc receptor antagonist for both divisions?
Nicotinic (fast/ionotropic)
Nicotine
What are the post ganglionic NTs for the sympathetic division?
NE and E (sweat glands use ACh)
What are the post ganglionic NTs for the parasympathetic division?
ACh
What type of receptors do sympathetic fibers use at the target organ?
Adrenergic (slow/metabotropic)
Phenylephrine and isoproterenol are the agonists.
What type of receptors do parasympathetic fibers use at the target organ?
Muscarinic (slow/metabotropic)
Muscarine is the agonist
What is the post-synaptic receptor type for neuron-neuron junctions?
Ionotropic/Fast
nicotinic AChR
What is the post-synaptic receptor type for neuron-viscera junctions?
Metabotropic/Slow
muscarinic AChR
What is the post-synaptic receptor type for neuron-skeletal muscle junctions?
Ionotropic/Fast
nicotinic AChR
