c.9 AutonomicNS-Test1.txt

characteristic of the ANS, there are (1) cell bodies in the ___ that synapse with (2) autonomic _____, and finally with the (3) ____ (smooth muscle)

_______ motor neurons conduct along a single axon, unlike the ____ which involves two neurons (pre & postganglionic)

preganglionic neurons are in the ___, postganglionic neurons are in the ___

________________ is compensation (more sensitive) by an effector organ to continue functioning even if ANS nerves are damaged

Rest and digest: _____ ; Fight or Flight: _______

_____ occurs in Sympathetic chain ganglia as Preganglionic fibers branch to synapse with numerous postganglionic neurons

________ occurs when a postganglionic neuron receives input from a large number of preganglionic fibers.

The ________ Nervous system preganglionic neurons only originate from between (thoracic)T1 down through (lumbar)L2 of the spinal cord.

The _____ nervous system may have preganglionic neurons originate from the mid & hindbrain or the low (sacral) S2-4 of the spinal cord

when shit gets real, the sympathetic nervous system's divergence and convergence of impulses causes __________

The adrenal medulla works under mass activation to release adrenaline, which assists the ____ nervous system

Sympathetic NS: efferent neurons exit the ___ root of the spinal cord

the _______ nerve ("wandering nerve") provides parasympathetic innervation to the heart, liver, GI, lungs, etc.

___ is the NT of all preganglionic fibers (SNS & PSNS)

Most postganglionic nerve fibers release __________ NT

_____ NS stimulates alpha and beta adrenergic receptors while the _______NS stimulates muscarinic receptors

innervated by both SNS and PSNS is called ____________, which may be antagonistic, complementary, or cooperative

__________ dual innervation : each NS does a different job to enhance the same outcome (i.e. PSNS saliva secretion + SNS blood vessel constriction= more saliva)

__________ dual innervation : each NS does a different job to allow something to work properly (i.e. PSNS arousal + SNS orgasm = sexual function)

drugs like _____________ (belladonna) are muscarinic antagonists

blushing, butterflies, and fainting are made possible by the _________ through the ANS

arrector pili muscles in the skin, sweat glands in the skin, most blood vessels, and the _________________ are NOT dual innervated

Sympathetic nerves that pass through the sympathetic chain without synapsing and instead synapse later in _________ (i.e. Celiac & superior/inferior mesenteric ganglion)

Parasympathetic nerves that innervate within the effector organ or very close to it are called _____________

terminal ganglia are in the _____ NS

collateral ganglia are in the _____ NS

epinephrine is a _________

norepinephrine is a __________
