Answer:
consists of a central core in the brainstem with neurons that radiate to the cortex
Question:
● Vomiting Center.
Answer:
the center in the brainstem that induces vomiting
Question:
● Vital Centers.
Answer:
centers in the brainstem that control such physiologic processes as blood pressure and pulse, depth
and rate of respiration
Question:
● Vestibular nerve.
Answer:
part of the eighth cranial nerve that is connect with equilibrium and hearing
Question:
,● Venule.
Answer:
any of the small vessels that collect blood from networks of capillaries and join them to form veins
Question:
● 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
Question:
● Ventricular rhythms.
Answer:
a cardia dsrhythmia in which the pacemaker is in the ventricles rather than in the SA node or atria
Question:
● Ventricular focus.
Answer:
a displace point of origin for a dysrhythmia that is in the ventricles
Question:
● Ventricular fibrillation.
Answer:
arrhythmia characterized by contractions of ventricle muscle fibers due to rapid excitation of
myocardial fibers without coordinated contraction of the ventricle
Question:
,● Sensory nerve.
Answer:
a nerve of the peripheral nervous system that conducts impulses from a sense organ to the spinal
cord or brain
Question:
● Sinoatrial node.
Answer:
a microscopic collection of heart muscle fibers where cardiac rhythm originates; also called the
pacemaker of the heart
Question:
● sinus arrhythmia.
Answer:
a cardiac dysrhythmia similar to normal sinus rhythm, but withslight variation in rate with
inspiration and expiration
Question:
● sinus bradycardia.
Answer:
cardiac dysrhythmia similar to normal sinus rhythm except for a slower rate of less than 60 bpm
Question:
● sinus rhythms.
Answer:
cardiac rhythms in which the pacemaker is the sinoatrial node
, Question:
● sinus tachycardia.
Answer:
dysrhythmia similar to normal sinus rhythm except for an increase in rate of greater than 100 bpm

Answer:
the amount of blood ejected from a ventricle during each beat of the heart

Answer:
beneath the skin
Question:
● 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
Question:

Answer:
central points of origin of dsrhythmias, which are located above the level of the ventricles in the
