What are the bony landmarks of the heart location?
Sternebrae 1-4 (manubriosternal complex)
Costal cartilages 2-6
T5-T8 (thoracic vertebrae)
What are the layers (and locations) of the pericardium?
Fibrous peridcardium (outside)
Serous pericardium (inside)
What are the two types of serous pericardium and their locations?
Visceral (outside of heart on epicardium)
Parietal (inner lining of fibrous pericardium)
What type of pericardium forms the two sleeves containing the great vessels?
What structure lies between these two sleeves?
Parietal serous pericardium
Transverse pericardial sinus
(Rx: ligatures in bypass)
What is the order of vessels branching from the aorta?
- Brachiocephalic trunk
- Left common carotid
- Left sublcavian
SVC is R & L brachiocephalic veins
What sulcus runs between the RA and RV?
Anterior atrioventricular or coronary sulcus
Where is the coronary sulcus located?
Between the RA and RV.
aka anterior atrioventricular groove
Where is the anterior interventricular sulcus?
Between RV & LV
What is the location of the posterior AAV groove/coronary sulcus?
Delineates where the LV ends and LA begins on the posterior aspect of the heart.
What valve is between the RA and RV?
Tricuspid/AV valve
Where is the tricuspid/AV valve?
Between RA & RV
What is the musculi pectinati?
Ridged muscle on internal anterior wall of RA
What lines the interior anterior wall of the RA?
Musculi pectinati and crista terminalis
What is the sinus venarum?
Smooth lining of the posterior interior wall of the RA
