Cards Anatomy (exam III) Flashcards
Dominance in the heart is determined by what?
Which arterty the posterior interventricular artery branches off of. Branching off of the RCA: Right dominant (most common) Branching off of the LCA: Left dominant
An accumulation of cholesterol and triglycerides into a fatty deposit inside of an artery is called_______. This is part of the processes leading to ASCVD
Atheroma
Name as many anatomical structures as you can
- Aorta (Ascedning or arch?)
- Superior Vena Cava
- Pulmonary Artery
- Pulmonary Veins
- Right Atrium
- Tricuspid Valve
- Right Ventricle
- Inferioir Vena Cava
- Pulmonary Artery
- Pulmonary Veins
- Left Atrium
- Mitral Valve
- Aortic Valve
- Left Ventricle
- Descending aorta
The pericardium has several layers
The outermost layer is called ________
The inner layer is called __________ and is divided into ________ layer and ________layer (that touches the heart )
Fibrous
Serous
Parietal
Visceral
You have a patient that presents with Hypotension, muffled heart sounds, and jugular venous distension while on one of your rotations. Your preceptor has you look at the CXR. The medical student that is also on your rotation thinks that this patient simply has cardiomegaly. But given the classic triad of ________ you know that the enlarged appearance of the heart is due to a __________. Once again you are a far superior student.
Cardiac tamponade
Pericardial effusion
Parasympathetic innervation to the heart comes from______ nerve
This causes ________ of the heart rate. ________ of the force of contraction and constricts that coronary arteries.
Vagus
Decrease
decrease
an increase in heart rate and force of contraction comes from the sympathetic innervation that arises from T__ to T__ to the cervical and upper thoracic sympathetic ganglia to the sympathetic trunk to the _________
T1 to T5
Cardiac plexus
The Right coronary artery supplies:
Right atrium
Right venticle
SA node
AV node
Atrial Septum
portion of the Left atrium
posteroinferior 1/3 of the interventricular septum
part of posterior left ventricle
The LCA supplies:
Left atrium
Interventricular septum
AV bundle and its branches
Pain from the parietal pericardium can be referred where?
a. left arm
b. right arm
c. supraclavicular area
d. upper back
C.
what is the mechanism called that causes the L. arm and the neck to feel pain due to myocardial ischemia?
Convergence projection mechanism
To listen to the aortic valve you should auscultate where?
Right second intercostal space
Mitral Valve disease can lead to increased pulmonary venous pressure? T or F
True.
This in turn can cause pulmonary edema and left sided heart failure
Aortic valve disease can lead to right sided heart failure? T or F
False. It leads to left ventricular hypertrophy and left sided heart failure
For your viewing pleasure
Can you tell whats going on here?
Pericardial effusion with cardiac tamponade
Again just for looksies
To orient yourself the right atrium is usually _______
Anterior
Can you tell what going on here…. something isnt right…
Right ventricular hypertrophy
