Visceral/Autonomic Motor System AMS/VMS Flashcards
what is the AMS organization
Hypothalamus
PreGanglionic
PostGanglionic
What divisions are the AMS split into
Sympathic
Parasympathic
What is the Sympathic division
The fight or flight response
What is the Parasympathetic division
Rest, digestive response
what does the Sympathic Division release
Epinephrine
Norepinephrine
what is the function of the Sympathic Ganglia Chain
Effector for the body wall, thoracic cavity, and head
What is the function of Sympathic Collateral ganglia
Effector of the body wall
What is the function of Adrenal Medullae
preganglionic fibers synapse with endocrine system
What is the function of Alpha Receptors in the Sympathic division
decrease in blood flow and or function
Strong to Norepinephrine
What is the function of Beta Receptors in the Sympathic division
Increase in Blood flow or function
balance epinephrine and norepinephrine
What is a Beta Blocker
prevent E and NE from activating beta adrenergic receptors
prevents elevated heart rate during stress
lowers cardiac metabolic rate
PRESCRIBED FOR ANGINA
What is a bronchodilator
activate beta adrenergic receptors dilates smooth muscle in airways reduces resistance to airflow patient breaths more easily PRESCRIBED FOR ASTHMA
7 Actions of the Sympathetic Division
Heightened mental alertness Increased metabolic rate Reduced digestive and urinary functions Energy reserves activated Increased respiratory rate and respiratory passageways dilate Increased heart rate and blood pressure Sweat glands activated
What does the Parasympathic Division release
Acetycholine
Parasympathic Terminal Ganglia
Paired, near target Organ
Parasympathic Intrmural Ganglia
Within a organ
What is the function of Nicotinic Receptors in the parasympathic division
Excitation
What is the function of Muscarinic Receptors in the parasympathic division
Acts Through Enzymes
Both inhibitory and excitatory
Actions of the Parasympathic Division
Conserves energy and promotes anabolic reactions
Decreased metabolic rate, heart rate, and blood pressure
Increased salivary and digestive glands secretion
Increased motility and blood flow in digestive tract
Urination and defecation stimulation
What is Nicotine
A dangerous toxin that binds to the nicotinic receptors and targets autonomic ganglia and skeletal neuromuscular
What are mushrooms and toadstools
They bind to the muscarine receptors and it targets parasympathic neuromuscular or neurogladular
Dual Innervation in relation to Sympathic
Wide spread, organs and tissues
Dual Innervation in relation to parasympathic
Only 1 and specific visceral structures
what is Autonomic Tone
ANS function
if a nerve is inactive..
increase in activity only
Nerve maintains background activity..
Both a increase and decrease in activity
If the Blood Vessel Dilates
Blood flow will increase blood pressure will decrease
If the blood vessel Constricts
Blood flow will Decrease blood pressure will increase
