DAANCE Flashcards
Wave of Depolarization
An Advancing wave of change reversal as the nerve impulse advances along the neuron
Wakefulness System
The system in the brain that maintains the state of consciousness of wakefulness.
Vomiting center
The center in the brainstem the induces the vomiting system
Vital center
Centers in the brainstem that control such physiological Processes as the blood pressure and pulse
Ventricular Nerve
Part of the eighth cranial nerve that is connected with Equilibrium and hearing
Venue
Any of the small vessels that collect the blood from the networks of capillaries and join them to form veins
Ventricular Tachycardia
A cardiac dysrhythmia in which there is rapid firing of an ectopic focus in the ventricles
140-200Bpm and a Wide QRS Complex with no P wave
Ventricular Rhythms
Cardiac Dysrhythmia in which the pacemaker is in the ventricles rather than the SA Node or atria
Ventricular Foci
A Displaced point of origin from a dysrhythmia that is in the ventricles
Ventricular Fibrillation
Arrhythmia characterized by contractions of the ventricle muscle fibers due to rapid excitation of the myocardial fibers without coordinated contractions of the ventricle
Ventricle
One of the cavities that have thick muscular walls that make up the bulk of the heart
Veins AKA Vena
The Vessel that carries blood from organs or other parts of the body back to the heart
Vasodilation
Dilation of the vessel, Especially dilation of the arteriole leading to increased blood flow to a part
Vasoconstrictors
Pharmacological agents that cause blood vessels to constrict
Vasoconstriction
The decreased in diameter of a vessel, constriction of arterioles leading to decreased blood flow
Vaporizer
A device that allows for the controlled evaporation and release of inhalation anesthetic agents for the administration of inhalation anesthetic
Vapocoolant
A chemical spray applied to the skin to rapidly cool the skins surface and desensitize it in preparation for venipuncture or an injection of medication
Vagus Nerve
The Tenth cranial nerve which supplies fibers to many parts of the body, including the ears, tongue, pharynx, larynx, and thoracic, and abdominal, viscera
Type II Diabetes
Non Insulin dependent diabetes
Adult onset diabetes
Which rarely requires insulin injections to regulate glucose levels
Type I Diabetes
Insulin dependent Diabetes
Juvenile Diabetes
Patients must receive insulin injections to regulate glucose levels
Trigeminal nerve
The Fifth cranial nerve which provides sensation to the face, teeth, mouth and nasal cavity, and supplies motor abilities to the facial muscles. (Muscle of mastication )
Transient ischemic attack (TIA)
A brief attack of cerebral dysfunction caused by reduced blood flow in the brain
Tracheostomy
The surgical creation of an opening into the trachea through the neck
Trachea
The tube descending from the larynx and branching in to the left and right main bronchi AKA the windpipe
Titrate
To Give a small quantity of a drug and assess its effects before giving additional drugs
Tidal Volume
The amount of gas that is inspired and expired during one respiratory cycle
Thrombosis
Formation of blood clots in a blood vessel, usually a vein
Third degree AV Block
An atrioventricular clock in which the impulse does not conduct from the atria to the ventricles and there is independent contraction of the atria and ventricles
Terminal Button
The Bulge at the end of the nerve that touches the next nerve in the nerve pathway at the synapse
Tachycardia
Fast heart rate grater that 100 Bpm
T wave
Ventricular Repolarization
Systolic
When the ventricles contract
Synergistic
The Phenomenon that exists when two drugs are administered together, and the combined effects is greater than the sum of its part
Syncope
Fainting
Temporary suspension of the consciousness due to generalized cerebral ischemia
Synaptic cleft
The gap between two nerves where they meet and a synapse
Synapse
The junctions between two neurons where impulses are transmitted from on neuron to another
