Autonomic pharm Flashcards
(40 cards)
All preganglionic neurons are
Ach – synapsing on nicotininc
Craniosacral
para
Thoracolumbar
symp
Post ganglionic of para
Ach – muscarinic
Parasympathetic organs
cardiac .. SM.. gland cells ,, nerve terminals
Controlled by Ach muscarinic
Para post ganglionic
these are cholinergic that releases Ach that interacts with muscarininc receptors .. Cardiac ..SM .. glands .. nerve terminals
Sympathetic post ganglionic
these are monoamine neurons mostly releasing NE and some dopamine.
Para has long neurons in the
pre
Para has short neurons in the
post
Sympathetic has short neurons in the
pre
Sympathetic has long neurons
in post
Cardiac and SM, gland cells , nerve terminals in parasympathetc innervated by
Ach– muscarinic
Sweat glands in sympathetic are innervated by
Ach M
Cardiac and smooth muscle, gland cells and nerve terminals in sympathetic innervated by
NE alpha and beta
Renal vascular and SM in sympathetic are innervated by
NE and D
alpha and D1
Adrenal medulla
Epi, NE
Somatic skeletal muscle
Ach N
Enteric nervous system
Controls GI
myenteric plexus
submucous plexus
NE can act as
locally or a hormone
Certain drugs such as Hemicholiniums can do what ?
Affect the transport of choline, but its not used in clinic s cause it would react with other things.
Ach choline synthesis requires
choline and AcCoA
After Ach is synthesized, it is stored in vesicles, but it has to to be what ?
transported into those vesicles
The vesicles that Ach are transported into
Have protein transporters which are responsible for transporting Ach from the cytoplasm into the vesicles. But, there are drugs that can block this process, so if the molecule is not being stored, it will be excreted by the presynaptic.
Drugs that block the Ach transporters are
Extacy and Amphetamines
