QuestionAnswer
the secretions of the adrenal medulla act to supplement the effects of sympathetic stimulation
in contrast to the somatic nervous system, the autonomic nervous system has two efferent neurons
preparing the body for the "fight of flight" response is the rold of the sympathetic nervous system
the parasympathetic nervous system is characterized by peripheral ganglia near the organs and by short postganglionic fibers
a drug that might be used to specifically to reduce heart rate in cardiac patients could be a beta-blocker
the parasympathetic ganglion that serves the eye is the ciliary ganglion
cardiovascular effects of the sympathetic division include all except dilation of the blood vessels serving the skin and digestive viscera
over 90% of all parasympathetic fibers are derived from 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 skeletal muscle
which of the following is not a result of the parasympathetic stimulation dilation of the pupils
the site of origin in the preganglionic fibers of the parasympathetic nervous system is the brain stem and the sacral region of the cord
sympathetic responses generally are widespread because single preganglionic axons make mulitple synapses with ganglionic neurons
sympathetic nerves may leave the spinal cord ate which vertebrae first thoracic
autonomic ganglia contain the cell bodies of motor neurons
the parasympathetic fibers of the ___ nerves innervate smooth muscles of the lens of the eye, the muscles that cause the eye to bulge to accomodate close vision oculomotr
fibers that enter and leave the sypmathetic chain without synapsing from structures called splanchnic nerves
which 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
the autonomic nervous system is directly controlled by the reticular formation of the brain stem
the white rami carry preganglionic axons to the sympathetic chain
beta-blockers attach mainly to the B1 receptors of cardiac muscle
erection of the penis or clitoris is primarily under parasympathetic control
which is uniquely sympathetic function regulation of body temperature
Raynauds's disease is characterized by exaggerated vascocontriction in the extremities
the mass reflex reaction represents a return of reflex activity with no controls from higher centers
in congenital megacolon (Hirschsprung's disease) the distal portion of the large intestine fails to develop parasympathetic innervation
in aging, autonomic inefficiency is often due to clogging of preganglionic axon terminals with filaments
sympathetic fibers leave the spinal cord in the thoracolumbar region, and the postganglionic fibers secrete norepinephrine
where would you not find autonomic ganglion in the armpit
sympathetic division stimulation causes increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure
the smooth muscle of the digestive viscera is served largely by the tenth cranial nerve
the route of major parasympathetic outflow from the head is the vagus nerve
parasympathetic functions include constriction of broncioles
all preganglionic axons of the autonomic nervous system release the same transmitter as the one released by the parasympathetic postganglionic axons
emotions influence autonomic reactions primarily through integration in the hypothalamus
the possibility of control over autonomic responses is demostrated by biofeedback
the vagus nerve does not innervate the parotid gland
