1 - Intro to Autonomic Pharmacology Flashcards
The nervous system is made of the _____ & _____
Central Nervous System & Peripheral Nervous System
The Peripheral Nervous System is made of the _______ & _______
Afferent & Efferent Divisions
The Efferent Division of the PNS is made of the _______ & ________
Somatic Nervous System & Autonomic Nervous System
The Autonomic Nervous System is made of the ____, ____, & _____
Sympathetic, Parasympathetic, & Enteric Nervous Systems
-mimetic
drug that mimics the action
-lytic
drug that blocks or terminates the action of corresponding system in the ANS
-ergic
refers to work or action; used to describe the action of the corresponding neurotransmitters
The sympathetic nervous system has (short/long) preganglionic nerves & (short/long) postganglionic nerves
Short, Long
The ______ nervous system has more thoracolumbar outflow & the _______ nervous system has more craniosacral outflow
Sympathetic, Parasympathetic
Do all organs have dual innervation?
No (exp. lacrimal glands - only parasympathetic, exp. kidney - only sympathetic)
Which organs only have sympathetic nervous system action?
Kidney, Adrenal medulla, Ureters & bladder, Genitalia, Blood vessels
Which organs only have parasympathetic nervous system action?
Lacrimal glands
A research intern has anesthetized a dog in the lab to study effect of vagal denervation. What do you expect if the vagal innervation of the heart is cut off?
The heart rate increases
An ophthalmologist needs to perform a funduscopic examination to visualize the retina. The pupils have to remain dilated to ensure proper visualization. However, the light from the fundoscope would cause reflex contraction of the iris. What category of drug would achieve dilation of the iris?
Sympathomimetic/Parasympatholytic
What neurotransmitter is used for all preganglionic neurons?
Acetylcholine
