Autonomic nervous system overview
- Sympathetic: The "Fight or Flight" response
- Increased HR and BP
- Pupil dilation
- Inhibits salivation
- Dilates bronchioles
- Inhibits digestion
- Increased glucose
- Peripheral vasoconstriction
- Relaxed bladder
- Ejaculation and orgasm
- Ejaculation and orgasm
- Relaxed bladder
- Peripheral vasoconstriction
- Norepinephrine
- Group called catecholamines
- Target organ
receptors called
adrenergic
receptors
- Alpha and
beta receptors
(pg 147)
- Alpha and
beta receptors
(pg 147)
- Broken down
by monoamine
oxidase
- Group called catecholamines
- Epinephrine
- Adrenal gland
most responsible
for release
- Activates
alpha and beta
receptors, but
has an affinity
for beta
- Terminated
through hepatic
metabolism
- Adrenal gland
most responsible
for release
- Increased HR and BP
- Prasympathetic: The "Rest and Digest" response
- Constricts pupils
- Stimulates salivation
- Slows heart rate, decreases contractility
- Constricts bronchioles
- Stimulates digestion
- Stimulates gallbladder function
- Contracts bladder
- Stimulates erection and lubrication
- Decreased HR and BP
- Decreased HR and BP
- Stimulates erection and lubrication
- Contracts bladder
- Stimulates gallbladder function
- Stimulates digestion
- Constricts bronchioles
- Slows heart rate, decreases contractility
- Stimulates salivation
- Acetylcholne
- Cholinergic nerves RELEASE Ach. Their receptors are:
- Nicotinic- Located at the
ganglionic synapse in
parasympathetic and
sympathetic NS
- Located in a
lot of places,
including
skeletal
muscle
- Activation
causes
tachycardia,
hypertension,
and increased
tone and
motility in
digestive
tract
- Very
little
clinical
use
- Located in a
lot of places,
including
skeletal
muscle
- Muscarinic- Located on
target tissues affected by
postganglionic neurons in
parasympathetic NS
- Nicotinic- Located at the
ganglionic synapse in
parasympathetic and
sympathetic NS
- Broken down by acetylcholinesterase (AchE
- Cholinergic nerves RELEASE Ach. Their receptors are:
- Constricts pupils
