The ANS
These are the primary targets of the ANS:
Also known as the agonistic effect, this division of the ANS prepares the body for physical activity, while this division calms the body down:
What are the sympathetic division and parasympathetic division?
This neurotransmitter is secreted by nearly all sympathetic postganglionic neurons (hint: you have a 50/50 chance at this):
What is NE?
All parasympathetic fibers are this:
What is cholinergic?
These can mimic, enhance, or inhibit the action of neurotransmitters:
What are medications and drugs?
The ANS carries out involuntary actions, oppsed to the _____, which involves mostly voluntary actions:
What is the Somatic Nervous System?
Normal background rate of activity that represents the balance of the two systems that shifts in response to body's needs:
What is autonomic tone?
Axons that secrete ACh, and receptors that bind ACh:
What are cholinergic fibers and cholinergic receptors?
Most sympathetic postganglionic fibers are this:
What is adrenergic?
Few sympathetic postganglionic fibers are this:
What is cholinergic?
These are unconscious, automatic, stereotyped responses, consisting of reflex arc:
What are visceral reflexes?
interconnected by longitudinal nerve cords, this results in sympathetic nerve fibers distributing to every level of the body:
What is sympathetic chain of ganglia?
These cholinergic receptors can excite or inhibit, and these cholinergic receptors bind to ACh and is always excitatory:
What are muscarinic and nicotinic?
Most viscera receive both sympathetic and parasympacthetic fibers. This is:
What is dual innervation?
What actions oppose eachother:
What is agonistic effect?
The ANS is considered the _____ pathway:
What is efferent?
____ is the myelinated 1st fiber, and ____ is the unmyelinated 2nd fiber:
What are the preganglionic fibers and postganglionic fibers?
Axons that secrete NE are _____, and receptors that bind NE are _____:
What are adrenergic fibers and adrenergic receptors?
What are receptors, afferent neurons, integrating centers, efferent neurons, and effectors?
These assist preganglionic nerve fibers in exiting the spinal cord:
What are communicating rami?
These NE receptors are usually excitatory, and these NE receptors are usually inhibitory:
What are alpha-adrenergic and beta-adrenergic?
