Wave of Depolarization - Correct Answer an advancing wave of charge reversal as the nerve impulse advance a long the neuron Wakefullness system - Correct Answer consists of a central core in the brainstem with neurons that radiate to the cortex Vomiting Center - Correct Answer the center in the brainstem that induces vomiting Vital Centers - Correct Answer centers in the brainstem that control such physiologic processes as blood pressure and pulse, depth and rate of respiration Vestibular nerve - Correct Answer part of the eighth cranial nerve that is connect with equilibrium and hearing Venule - Correct Answer any of the small vessels that collect blood from networks of capillaries and join them to form veins Ventricular tachycardia - Correct 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 - Correct Answer a cardia dsrhythmia in which the pacemaker is in the ventricles rather than in the SA node or atria Ventricular focus - Correct Answer a displace point of origin for a dysrhythmia that is in the ventricles Ventricular fibrillation - Correct Answer arrhythmia characterized by contractions of ventricle muscle fibers due to rapid excitation of myocardial fibers without coordinated contraction of the ventricle Sensory nerve - Correct Answer a nerve of the peripheral nervous system that conducts impulses from a sense organ to the spinal cord or brain Sinoatrial node - Correct Answer a microscopic collection of heart muscle fibers where cardiac rhythm originates; also called the pacemaker of the heart sinus arrhythmia - Correct Answer a cardiac dysrhythmia similar to normal sinus rhythm, but withslight variation in rate with inspiration and expiration 1 / 2
sinus bradycardia - Correct Answer cardiac dysrhythmia similar to normal sinus rhythm except for a slower rate of less than 60 bpm sinus rhythms - Correct Answer cardiac rhythms in which the pacemaker is the sinoatrial node sinus tachycardia - Correct 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 - Correct Answer the amount of blood ejected from a ventricle during each beat of the heart subcutaneous - Correct Answer beneath the skin superior vena cava - Correct 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 - Correct Answer central points of origin of dsrhythmias, which are located above the level of the ventricles in the atria sympathommimetic - Correct Answer having activity that mimics the effects of the sympathetic nervous system, epinephrine synapse - Correct Answer the junction between two neurons where impulses are transmitted from one neuron to another synaptic cleft - Correct Answer the gap between two nerves where they meet at a synapse syncope - Correct Answer fainting synergistic - Correct Answer the phenomenon that exists when two drugs are administered together, and the combined effect is greater than the sum of its parts systolic - Correct 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 - Correct Answer the EKG waveform that represents repolarization of the ventricles Tachycardia - Correct Answer fast heart rate terminal button - Correct Answer the bulge at the end of the nerve that touches the next nerve in the never pathway at a synapse
