Autonomic Nervous System Chapter 12
The transmitter of the preganglionic fibers of both the PNS and SNS is
ACh
alpha and beta receptors are activated by
NE
Nicotinic receptors are located in both
PNS and SNS
vasomotor tone is
a vasoconstrictor effect caused by background firing of the sympathetic nerves
The transmitter for the postganglionic fibers of the PNS is
acetylcholine (ACh)
alpha and beta adrenergic receptors are
activated by norepinephrine
red colored fibers are
adrenergic
sympathetic
adrenergic
alpha and beta receptors are
adrenergic receptors
sympathetic
anxiety and tremors
nicotinic receptors within the neuromuscular junction
are activated by Ach
paravertebral ganglia
are located within the sympathetic nervous system
The preganglionic and postganglionic fibers associated with the craniosacral outflow are
cholinergic
green colored fibers are
cholinergic
muscarinic and nicotinic receptors are
cholinergic receptors
The preganglionic fibers of the PNS and SNS are
cholinergie
parasympathetic
constriction of the pupil of the eye
parasympathetic
craniosacral outflow
parasympathetic
decreased heart rate
sympathetic
dilation of the breathing passages
sympathetic
dilation of the pupils of the eyes
parasympathetic
feed - and - breed
sympathetic
fight - or- flight
sympathetic
increased blood pressure
sympathetic
increased heart rate
sympathetic
increased perspiration
sympathetic and parasympathetic nerves
innervate the viscera
the postganglionic receptors for the PNS are
muscarinic
which of the following is least descriptive of the thoracolumbar outflow
muscarinic and nicotinic receptors
the transmitter of the preganglionic fibers of both the PNS and SNS activate
nicotinic receptors
The transmitter for the postganglionic fibers of the SNS is
norepinephrine
parasympathetic
paradoxical fear, 'bradying down"
drugs that block the effects of ACh affect both the sympathetic and
parasympathetic nervous system
a drug that blocks muscarinic receptors diminishes the
parasympathetic response
sympathetic
paravertebral ganglia
alpha and beta receptors
postganglionic receptro
sympathetic
pounding heart and sweaty palms
what is the clinical consequence of loss of vasomotor tone
severe decline in blood pressure and shock
a drug that blocks the N(m) receptors within the neuromuscular junction causes
skeletal muscle paralysis
parasympathetic
stimulation of urination
sympathetic
stressed - out and uptight
sympathetic
stronger heart muscle contraction
preganglionic fibers of the parasympathetic nervous system are longer than the preganglionic fibers of the
sympathetic nervous system
a drug that blocks alpha or beta receptors diminishes a
sympathetic response
stimulation of the SNS causes the heart to beat stronger and faster is described as
sympathomimetic
the adrenal medulla secretes epinephrine and norepinephrine; the effects of the hormones are best described as
sympathomimetic
a drug that affects the N receptors affect both
the PNS and SNS
what is least true of the sympathetic nervous system
the postganglionic receptors is muscarinic
what is the most descriptive of the parasympathetic nervous system
the postganglionic receptors is muscarinic
The preganglionic fibers of the SNS exit the spinal cord at
the thoracolumbar region
sympathetic
thoracolumbar outflow
sympathetic
vasoconstriction
sympathetic
vasomotor tone
