all of the neurotransmitters
Where would you not find a cholinergeric nicotinic receptor?
all parasympathetic target organs
The parasympathetic ganglion that serves the eye is the
ciliary ganglion
Cardiovascular effects of the sympathetic divison include all except
dialiation of the blood vessels serving the skin and digestive viscera
Over 90% of all parasympathetic fibers are derived from the cranial nerve number
X
The “resting and digesting” division of the autonomic nervous system is the
parasympathetic division
Control of temperature , endocrine activity, and thirst are functions associated with the
hypothalamus
Which of these effectors is not directly controlled by the autonomic nervous system?
increased peristalsis of the digestive viscera
Which of the following statements is not true?
Sympathetic origin is craniosacral, parasympathetic is thoracolumbar.
Sympathetic responses generally are widespread because
NE and epinephrine are secreted into the blood as part of the sympathetic response
Sympathetic nerves may leave the spinal cord at which vertebra?
first thoracic
Autonomic ganglia contain
the cell bodies of motor neurons
The parasympathetic fibers of the __________nerves innervates smooth muscles of the eye that cause the lenses to bulge to accomodate close vision
oculomotor
Fibers that enter and leave the sympathetic chain without synapsing form structures called
splanchnic nerves
Which of the following is not a plexus of the vagus nerve?
celiac
Visceral reflex arcs differ from somatic in that
visceral arcs involve two motor neurons
The parasympathetic tone
determines normal activity of the urinary tract
Once a sympathetic preganglionic axon reaches a trunk ganglion, it can do all but which one of the following?
synapse with a parasympathetic neuron in the same trunk ganglion
Which of the following appears to exert the most direct influence over the autonomic function?
reticular formation
Erection of the penis or clitoris
is primarily under parasympathetic control
Which is a uniquely sympathetic function?
regulation of body temperature
Raymond’s disease
is characterized by exaggerated vasoconstriction in the extremities
Autonomic dysreflexia
involves uncontrolled activatio of autonomic neurons
Which sympathetic fibers from a splanchhnic nerve?
those that pass through the trunk ganglion to synapse in collateral or prevertebral ganglia
Which of the following adrenergic neurotransmitter receptors plays the major role in heart activity
beta 1
Where would you not find an autonomic ganglion?
in the armpit
The route of major parasympathetic outflow from the head is via the
vagus nerve
Parasympathetic functions include
lens accomodation for close vision
Emotions influence autonomic reactions primarily through integration in the
hypothalamus
Alpha and beta receptors are classes of
adrenergic receptors
Sweat glands are innervated by the
sympathetic fibers alone
A division alone that adaptss the lens of the eye for close vision
parasympathetic divison
The two cholinergic receptor types are nicotonic and
muscarinic
A receptor type is used by the heart, and when activated increases heart rated
B1
The only sympathetic preganglionic neuron to go directly to an organ is one branch of the
greater splanchnic nerve
The parasympathetic division uses only_____________ as a neurotransmitter in the ganglionic neurons
acetlycholine
