AND CORRECT ANSWERS (VERIFIED ANSWERS) |
AGRADE
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
