RELIABLE ANSWERS / 100% SOLVED / ALREADY
GRADED A+
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
