Heart Anatomy Flashcards
Name the conducting pathway of the heart in order.
SA, AV, Bundle of His, R+L bundle branches, Perkinje fibres.
What’s the name of the bundle that conducts the SA potential to the left atrium again?
Bachmann’s bundle.
What’s the right ventricle’s equivalent of the aorta?
Pulmonary trunk.
The semilunar valves separate the atria/ventricles or the ventricles/arteries?
The semilunar valves border the ventricles and the arteries.
The semilunar valves are called the ________ valve and the _________ valve.
pulmonary valve
aortic valve
Just to reiterate in a different way, the left semilunar valve is at the base of the _______ while the right semilunar valve is at the base of the _________.
Left: base of the aorta
Right: base of the pulmonary trunk
What’s the one artery in the entire body that carries deoxygenated blood? Where does it emerge from?
The PULMONARY trunk
from the RIGHT ventricle
What’s the one vein in the entire body that carries oxygenated blood? Where does it emerge from?
The PULMONARY vein
We knew about the superior and inferior vena cava - what’s the third vein entry into the heart?
The coronary sinus. It pokes in from the back around about the level of the coronary sulcus.
What’s the valve with the confusing double name for some reason?
bicuspid aka mitral valve.
Just remember “trail bike” i.e miTRAL and BICuspid.
What is cited as the normal resting heart beat?
72bpm.
Cranial Nerve X is called the _____ nerve.
Vagus.
The ___ nerve provides the parasympathetic innervation to the heart and reduces the constitutive SA ____ bpm down to a reasonable ___ bpm.
vagus; 120bpm; 70-80
The SA node wants to beat at ___ bpm but vagus control holds it down at ___.
120; 70-80
What does “sternocostal” mean?
That’s the word for what the heart looks like from the front. I.e. the view that’s mostly left ventricle.
The posterior view is the “diaphragmatic” side.
What’s another word for the Bundle of His?
The atrioventricular bundle.
The three parts of the aorta are easy. What are they?
The ascending aorta goes up out of the left ventricle,
The aortic arch arches (has the offshoots)
The descending aorta descends off the arch.
The pulmonary trunk splits into the what?
The left and right pulmonary arteries.
The right and left coronary arteries originate from the __________ artery just above the level of the ___________.
ascending aorta
aortic (left semilunar) valve
The left coronary artery wraps around from ________ and the right coronary artery wraps around from _______.
Left: wraps from behind.
Right: wraps from in front.
The _______ and ________ _________ pericardia sandwich the pericardial fluid. The __________ is heart-facing and the __________ is fibrous-facing.
visceral and parietal serous pericardia;
visceral: heart facing
parietal: fibrous facing
