Surface anatomy, chambers, blood supply and venous drainage
What is the surface markings of the heart?
2nd ICS; left of sternum
3rd CC; on the right
6th CC; on the right
5th ICS; left MCL
What are the two parts of the mediastinum?
Inferior is divided into posterior, middle, and anterior
What are the layers of the epicardium?
(Parietal and visceral)
This is a double-walled sac which contains the heart.
This is the space between the parietal pericardium and visceral pericardium
What forms the right border of the heart?
What forms the anterior border of the heart?
Apex of left ventricle
What forms the base (posterior) of the heart?
What forms the left margin of the heart?
The most inferior and lateral part of the heart where you can hear a beat
it should be 5th ICS MCL
What are branches of RCA?
Where does the RCA arise from? (hint: cusps)
Sinus of anterior aortic cusp
Where does the LCA arise from?
Sinus of the Left Posterior Aortic Cusp
What are the branches of the LCA?
Which branch supplies the cardiac
Which branch supplies the
of the heart?
What is the main venous drainage of the heart?
Great, Middle, Small cardiac veins --> Coronary sinus --> right atrium
Anterior vein --> right atrium
Thebesian Veins --> chamber
By which arteries do the Great, Middle, and Small cardiac veins run?
GCV with the AIVA
MCV with the PIVA
SCV with the marginal
What is blood supply to left atrium?
What supplies the apex of the heart?
What vertebral levels is the atrium?
to 6 CC
This seperates the 2 parts of the atrium (primitive and true atrium)
This is found where the sulcus terminalis meets the SVC
External groove between SVC and IVC
This node is found in the inter-atrial septum just above the coronary sinus.
