lecture 4 Flashcards
parasympathetic origin pre/post ganglionic long ganglion is closer to discrete/generalized
craniosacral ( 1973C / s2-s4)
long-short
effector organ
discrete
sympathetic origin pre/post ganglionic long ganglion is closer to discrete/generalized
t1-l3
short-long
origin
generalized
ANS carries out voluntary activities of
the body to maintain homeostasis(T/F)
FALSE involuntary
Parasympathetic is rest & digest or
feeding & breeding
Sympathetic is fight or flight
(T/F)
true
Neurotransmitters - Receptors for each : Somatic (NMJ) Ganglia (both) Sympathetic Parasympathetic
ach - NM (Nicotinic)
ach - NN(Nicotinic)
{ NE - Adrenergic there’s exception for sweat glands and piloerector muscles are ach - M (Nicotinic) }
ach - M (Nicotinic)
receptors affected by Ach are called ?
cholinergic receptors
The preganglionic fibers of Sympathetic receptor is?
cholinergic
Catecholamines are:
Norepinephrine, epinephrine (adrenaline), Dopamine
blood vessels (arteries & veins), sweat glands are dominant in (symp /para )?
symp
organ that is only innervated by parasympathetic:
ciliary muscles in the eye
organs are only innervated by sympathetic :
: sweat glands & piloerector muscle,
adrenal medulla, kidney, blood vessels, liver
organ that have both symp and paramsymp and they don’t act oppositely is : and how?
Penis; sympathetic causes ejaculation, Parasympathetic causes erection
ciliary muscles is
controlled by (symp /para)
receptor is :
what’s the action :
parasymp
M3
miosis by contraction of
circular muscles
Lungs if stimulated by symp parasymp 1 what's the action 2 receptors of each
Bronchodilation & decrease
secretions [B2]
Bronchoconstriction & increase
secretions [M3]
Heart receptors on each symp / parasymp
Parasymp { m2}
symp {b1}
to Reduce motility of GIT we stimuli (symp/parasymp )
what’s the receptor
symp
B2
Sphincters contraction RECEPTOR ?
a1
Urinary Bladder if
symp dominant
parasymp dominant
symp :Relaxation bladder wall [B2],
contraction sphincter [a1]
contraction of bladder wall, and
relaxation of sphincter [M3]
Female Genitalia controlled by
symp B2
Blood Vessels if symp stimulated
Skeletal muscle: vasodilation [B2]
Internal organs & skin:
Vasoconstriction [a1]
kidney & symp effect :
Increase renin [B1]
Renal arteries vasodilation [D1]
fat metabolism & symp :
Fat tissue: induce lipolysis [B3]
increase glucose
