Week 10: Heart and Pericardium Flashcards
Continuation of the fibrous pericardium in large and small animal
Small - phrenicopericardial ligament
Large - sternopericardium
Three parts of the serous pericardium
- Visceral pericardium (epicardium)
- Parietal pericardium
- Pericardial cavity
Azygous vein in cow/horse/dog
Dog: right
Horse: right
Cow: left or bilateral
Apex
Left ventricle
Feature of right ventricle
Conus arteriosus
Groove on auricular surface
Paraconal interventricular groove
Paraconal interventricular groove contains
Great cardiac vein and left coronary artery
Groove on the atrial surface
Subsinuosal interventricular groove
Subsinuosal interventricular groove contains
Circumflex branch of the left coronary artery
Right atrium is divided into
Sinus and auricle
4 openings of the right atrium
- Coronary sinus
- Caudal vena cava
- Cranial vena cava
- Atrioventricular orifice
What diverts blood from cranial and caudal vena cava into the right ventricle
Intervenous tubercle
Right auricle is strengthened by
Interlacing pectinate muscles
Crista terminalis
The dorsal separation of sinus venarum and auricle
Ventricle’s papillary muscles
Conical shaped projections
Ventricle’s chordae tendinae
Chords that extend from the cusps of the AV valve to the papillary muscles
Ventricle’s trabeculae carneae
Myocardial ridges
Cusps of the atrioventricular valves
- Septal
- Parietal
Foramen ovale in fetus allows for
Passage from right atrium to left atrium
Ductus arteriosus in the fetus
Shunts blood from pulmonary artery to the aorta
Ductus arteriosus turns into
ligamentum arteriosus
Pericardial effusion
Accumulation of fluid in pericardial sac
Dilated cardiomyopathy
Decreased contractility
Most common cardiac disease in cats
Hypertrophic cardiomyopathy
