Sympathetic Nervous System - CORRECT ANSWERS the division of the autonomic
nervous system that arouses the body, mobilizing its energy in stressful situations (Fight or
Flight) EPI and NorEPI
Parasympathetic Nervous System - CORRECT ANSWERS the division of the autonomic
nervous system that calms the body, conserving its energy (Feed or Breed)
Norepinephrine - CORRECT ANSWERS affects arousal and memory; raises blood
pressure by causing blood vessels to become constricted, but also carried by bloodstream to
the anterior pituitary which relaxes ACTH thus prolonging stress response
(levophed)
Atropine - CORRECT ANSWERS anti-cholinergic drug that acts on muscarinic receptors.
anti-parasympathetic drug, blocks the Parasympathetic NS not stimulating the Sympathetic NS
Bundle Branch Block - CORRECT ANSWERS heart block; occurs when electrical impulse
is blocked from traveling down the bundle branches; results in the ventricles beating at a
different rate than the atria
Right Bundle Branch Block - CORRECT ANSWERS widened QRS (>0.12s); double peaked
QRS in V1 (best to look in V1 and V2); T wave can look abnormal - inverted (does not indicate
ischemia)
Right Bundle Branch - CORRECT ANSWERS carry electricity through right ventricle 20 -
40 bpm
Left Bundle Branch - CORRECT ANSWERS carries electricity through left ventricle 20 -
40 bpm

Right Coronary Artery - CORRECT ANSWERS supplies blood to right atrium, portions of
both ventricles and cells of AV nodes and SA node.
Left Coronary Artery - CORRECT ANSWERS Branches into two arteries: 1. Anterior
interventricular artery - also called the left anterior descending artery, supplies the anterior
surface of both ventricles and most of the interventricular septum 2. Circumflex artery -
supplies the left atrium and ventricle
SA Node - CORRECT ANSWERS the pace-maker of the heart; where the impulse
conduction of the heart usually starts; located in the top of the right atrium
AV Node - CORRECT ANSWERS an area of specialized tissue between the atria and the
ventricles of the heart, which conducts the normal electrical impulse from the atria to the
ventricles.
Perkinje Fibers - CORRECT ANSWERS End of the conduction system; sends impulses
through the ventricles, causing them to contract
Bundle of HIS - CORRECT ANSWERS neurological fibers, extending from the AV node to
the right and left bundle branches, that fire the impulse from the AV node to the Purkinje fibers
AV Junction - CORRECT ANSWERS The atrioventricular junction; the portion of the
electric conduction system of the heart located in the upper part of the interventricular septum
that conducts the excitation impulse from the atria to the bundle of His
Atria - CORRECT ANSWERS the upper chambers of the heart
