The part of the heart that contracts
What is the myocardium
100
The two nodes in the heart
What is the AV and SA node
100
The hormone secreted by the Parasympathetic NS
What is acetylcholine
100
The disease condition meaning abnormal heart rate
What is Arrythmia
100
The number of ion channels that work in concert for a pacemaker cell to function properly
What is 5
200
The part of the heart that touches the blood in the vascular system
What is Endocardium
200
3 structures defined as conductile cells
What is the purkinje fibers, the R/L bundle branches
200
The hormone secreted by the sympathetic chain
What is norepinephrine
200
The disease involving a valve defect
What is a heart murmur
300
The part of the heart that touches organs and tissues outside of the heart
What is Epicardium
300
The nerve that innervates the AV and SA nodes but NOT the myocardium
What is the vagus nerve
300
The hormone released tonically by the Vagus nerve that is mostly responsible for athlete's slower heart rate
What is Ach
300
The normally harmless condition that is felt by a large 'thump' in the chest
What is premature ventricular contraction
400
Part of the heart that electrically insulates the ventricles from the atria
What is the fibrous partition
400
The branch of the nervous system that secretes norepinephrine
What is sympathetic chain
400
A hormone that isn't secreted onto the myocardium
What is norepinephrine
400
The disease state that is rarely fatal but could cause a stroke
What is atrial fibrillation
400
After Ach binds to this protein, it activates or deactivates ion channels
What is muscarinic Ach receptors (MAChR)
500
I am a recently oxygenated blood cell- if I pass through one valve where am I?
The left ventricle
500
An injury to this part of the conduction system would ensure that a signal could NOT be conducted from the right atrium into the area of the ventricles
What is the bundle of His
500
The part of the nervous system that decreases the strength of contraction in the heart
What is the parasympathetic nervous system
500
The most lethal of the cardiac arrhythmia's
What is ventricular fibrillation
500
Daily Double: I am a blood cell and feeling blue as I return to the heart through the Superior Vena cava. I pass through 5 valves found in the heart and want to know where I am.
What is the right ventricle
