DAANCE STUDY EXAM (2025) QUESTIONS AND
(elaborated) WITH COMPLETE SOLUTIONS
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
