DAANCE Exam
Wave of Depolarization - ✔✔an advancing wave of charge reversal as the nerve impulse advance a long
the neuron
Wakefullness system - ✔✔consists of a central core in the brainstem with neurons that radiate to the
cortex
Vomiting Center - ✔✔the center in the brainstem that induces vomiting
Vital Centers - ✔✔centers in the brainstem that control such physiologic processes as blood pressure and
pulse, depth and rate of respiration
Vestibular nerve - ✔✔part of the eighth cranial nerve that is connect with equilibrium and hearing
Venule - ✔✔any of the small vessels that collect blood from networks of capillaries and join them to
form veins
Ventricular tachycardia - ✔✔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 - ✔✔a cardia dsrhythmia in which the pacemaker is in the ventricles rather than in
the SA node or atria
Ventricular focus - ✔✔a displace point of origin for a dysrhythmia that is in the ventricles
Ventricular fibrillation - ✔✔arrhythmia characterized by contractions of ventricle muscle fibers due to
rapid excitation of myocardial fibers without coordinated contraction of the ventricle
Sensory nerve - ✔✔a nerve of the peripheral nervous system that conducts impulses from a sense organ
to the spinal cord or brain
,Sinoatrial node - ✔✔a microscopic collection of heart muscle fibers where cardiac rhythm originates;
also called the pacemaker of the heart
sinus arrhythmia - ✔✔a cardiac dysrhythmia similar to normal sinus rhythm, but withslight variation in
rate with inspiration and expiration
sinus bradycardia - ✔✔cardiac dysrhythmia similar to normal sinus rhythm except for a slower rate of
less than 60 bpm
sinus rhythms - ✔✔cardiac rhythms in which the pacemaker is the sinoatrial node
sinus tachycardia - ✔✔dysrhythmia similar to normal sinus rhythm except for an increase in rate of
greater than 100 bpm but less than 150 bpm
stroke volume - ✔✔the amount of blood ejected from a ventricle during each beat of the heart
subcutaneous - ✔✔beneath the skin
superior vena cava - ✔✔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 - ✔✔central points of origin of dsrhythmias, which are located above the level of
the ventricles in the atria
sympathommimetic - ✔✔having activity that mimics the effects of the sympathetic nervous system,
epinephrine
synapse - ✔✔the junction between two neurons where impulses are transmitted from one neuron to
another
synaptic cleft - ✔✔the gap between two nerves where they meet at a synapse
, syncope - ✔✔fainting
synergistic - ✔✔the phenomenon that exists when two drugs are administered together, and the
combined effect is greater than the sum of its parts
systolic - ✔✔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 - ✔✔the EKG waveform that represents repolarization of the ventricles
Tachycardia - ✔✔fast heart rate
terminal button - ✔✔the bulge at the end of the nerve that touches the next nerve in the never pathway
at a synapse
third degree AV block - ✔✔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
Thrombosis - ✔✔formation of a blood clot in a blood vessel, usually a vein
Tidal Volume - ✔✔the amount of gas that is inspired or expired during one respiratory cycle
titrate - ✔✔to give a small quantity of a drug and assess its effects before giving additional drugs
trachea - ✔✔windpipe
tracheostomy - ✔✔the surgical creation of an opening into the trachea through the neck
