Wakefullness system - (ANSWERS)consists of a central core in the brainstem with neurons that
radiate to the cortex
Vomiting Center - (ANSWERS)the center in the brainstem that induces vomiting
Vital Centers - (ANSWERS)centers in the brainstem that control such physiologic processes as
blood pressure and pulse, depth and rate of respiration
Vestibular nerve - (ANSWERS)part of the eighth cranial nerve that is connect with equilibrium
and hearing
Venule - (ANSWERS)any of the small vessels that collect blood from networks of capillaries and
join them to form veins
Ventricular tachycardia - (ANSWERS)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 - (ANSWERS)a cardia dsrhythmia in which the pacemaker is in the
ventricles rather than in the SA node or atria
Ventricular focus - (ANSWERS)a displace point of origin for a dysrhythmia that is in the
ventricles
Ventricular fibrillation - (ANSWERS)arrhythmia characterized by contractions of ventricle
muscle fibers due to rapid excitation of myocardial fibers without coordinated contraction of
the ventricle
Sensory nerve - (ANSWERS)a nerve of the peripheral nervous system that conducts impulses
from a sense organ to the spinal cord or brain
Sinoatrial node - (ANSWERS)a microscopic collection of heart muscle fibers where cardiac
rhythm originates; also called the pacemaker of the heart
Sinus arrhythmia - (ANSWERS)a cardiac dysrhythmia similar to normal sinus rhythm, but
withslight variation in rate with inspiration and expiration
Sinus bradycardia - (ANSWERS)cardiac dysrhythmia similar to normal sinus rhythm except for
a slower rate of less than 60 bpm
Sinus rhythms - (ANSWERS)cardiac rhythms in which the pacemaker is the sinoatrial node

Sinus tachycardia - (ANSWERS)dysrhythmia similar to normal sinus rhythm except for an
increase in rate of greater than 100 bpm but less than 150 bpm
Stroke volume - (ANSWERS)the amount of blood ejected from a ventricle during each beat of
the heart
Subcutaneous - (ANSWERS)beneath the skin
Superior vena cava - (ANSWERS)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 - (ANSWERS)central points of origin of dsrhythmias, which are located
above the level of the ventricles in the atria
Sympathommimetic - (ANSWERS)having activity that mimics the effects of the sympathetic
nervous system, epinephrine
Synapse - (ANSWERS)the junction between two neurons where impulses are transmitted from
one neuron to another
Synaptic cleft - (ANSWERS)the gap between two nerves where they meet at a synapse
Syncope - (ANSWERS)fainting
Synergistic - (ANSWERS)the phenomenon that exists when two drugs are administered
together, and the combined effect is greater than the sum of its parts
Systolic - (ANSWERS)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 - (ANSWERS)the EKG waveform that represents repolarization of the ventricles
Tachycardia - (ANSWERS)fast heart rate
Terminal button - (ANSWERS)the bulge at the end of the nerve that touches the next nerve in
the never pathway at a synapse
Third degree AV block - (ANSWERS)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 - (ANSWERS)formation of a blood clot in a blood vessel, usually a vein
