DAANCE Exam Questions And Answers
Wave of Depolarization - Answer an advancing wave of charge reversal as the nerve
impulse advance a long the neuron
Wakefullness system - Answer consists of a central core in the brainstem with neurons
that radiate to the cortex
Vomiting Center - Answer the center in the brainstem that induces vomiting
Vital Centers - Answer centers in the brainstem that control such physiologic processes
as blood pressure and pulse, depth and rate of respiration
Vestibular nerve - Answer part of the eighth cranial nerve that is connect with
equilibrium and hearing
Venule - Answer any of the small vessels that collect blood from networks of capillaries
and join them to form veins
Ventricular tachycardia - Answer a cardia dsrhythmia in which there is rapid firing of an
ectopic focus in the ventricles and a wide QRS complex with no p waves
Ventricular rhythms - Answer a cardia dsrhythmia in which the pacemaker is in the
ventricles rather than in the SA node or atria
Ventricular focus - Answer a displace point of origin for a dysrhythmia that is in the
ventricles
Ventricular fibrillation - Answer arrhythmia characterized by contractions of ventricle
muscle fibers due to rapid excitation of myocardial fibers without coordinated
contraction of the ventricle
Sensory nerve - Answer a nerve of the peripheral nervous system that conducts
impulses from a sense organ to the spinal cord or brain
Sinoatrial node - Answer a microscopic collection of heart muscle fibers where cardiac
rhythm originates; also called the pacemaker of the heart
sinus arrhythmia - Answer a cardiac dysrhythmia similar to normal sinus rhythm, but
withslight variation in rate with inspiration and expiration
, sinus bradycardia - Answer cardiac dysrhythmia similar to normal sinus rhythm except
for a slower rate of less than 60 bpm
sinus rhythms - Answer cardiac rhythms in which the pacemaker is the sinoatrial node
sinus tachycardia - Answer dysrhythmia similar to normal sinus rhythm except for an
increase in rate of greater than 100 bpm but less than 150 bpm
stroke volume - Answer the amount of blood ejected from a ventricle during each beat
of the heart
subcutaneous - Answer beneath the skin
superior vena cava - Answer the venous trunk that drains blood from the head, neck,
upper extremities, and chest and empties into the right atrium of the heart
supraventricular foci - Answer central points of origin of dsrhythmias, which are located
above the level of the ventricles in the atria
sympathommimetic - Answer having activity that mimics the effects of the sympathetic
nervous system, epinephrine
synapse - Answer the junction between two neurons where impulses are transmitted
from one neuron to another
synaptic cleft - Answer the gap between two nerves where they meet at a synapse
syncope - Answer fainting
synergistic - Answer the phenomenon that exists when two drugs are administered
together, and the combined effect is greater than the sum of its parts
systolic - Answer pertaining to the phase of the heart's pumping action when the
ventricles contract, forcing blood either to the lungs or peripheral circulation
T wave - Answer the EKG waveform that represents repolarization of the ventricles
Tachycardia - Answer fast heart rate
terminal button - Answer the bulge at the end of the nerve that touches the next nerve in
the never pathway at a synapse
third degree AV block - Answer an atrioventricular block in which the impulse does not
conduct from the atria to the ventricles and there is independent contraction of the atria
and ventricles
