Learners with complete solution
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
transient ischemic attack
