The Pericardium And Heart Flashcards
Blood supply to the pericardium is mainly by. and branches of the internal thoracic artery
Pericardiacophrenic
Musculophrenic
Other sources of blood supply to the pericardium apart from pericardiacophrenic and musculophrenic branches of the internal artery include
a. Bronchial, esophageal and superior phrenic arteries from thoracic aorta
b. Coronary arteries
I am a fibrous closed sac that contains the heart and adjoining parts of great vessels
Pericardium
The pericardium lies to the sternum and costal cartilages of the left rib 2 to .
Posterior
6
The two sacs of the pericardium
a.Outer fibrous sac
b. Inner serosal sac
The fibrous sac is attached to the of the great vessels, central of the diaphragm and anteriorly by ligaments
roots
tendon
sternum
sternopericardial
The two layer of serous pericardium
a. Parietal layer
b. Visceral layer
Space between the parietal and visceral layers
Pericardial space
Pericardial sinuses in the pericardial space
Transverse
Oblique
The nerve supply to the pericardium
Phrenic nerve (C3- C5)
Vagus
Sympathetic trunk
Venous drainage of the pericardium is from the veins to vein. Other smaller tributaries drain into the system.
Pericardiacophrenic
brachiocephalic
azygous
Inflammation of the pericardium
Pericarditis
Accumulation of fluid in the pericardial sac
Pericardial effusion
A life threatening condition in which the accumulation of fluid in the pericardial sac compresses the heart, preventing it form pumping blood effectively
Cardiac temponade
It is an extra heart sound that is caused by the inflamed pericardium rubbing against the heart
Pericardial friction rub
Shape of the heart
Conical or pyramidal in shape
Surfaces of the heart
Anterior; which is the surface
Inferior; which is the surface
Right and left surfaces
sternocostal
diaphragmatic
pulmonary
Why is the apex of the heart important?
Because we listen over the apex for the mitral valve sound
The apex of the heart is most commonly behind the intercostal space and near a little to the midclavicular line
5th
medial
The base of the heart is formed mainly by the
Left atrium
The inferior surface of the heart is separated from the anatomical base by
which is also known as the
Atrioventricular groove
Coronary sinus
What is the left pulmonary surface of the heart traversed by
Coronary sinus
The three grooves of the heart
a. anterior interventricular groove
b. Coronary sinus
c. Posterior interventricular groove b
What separates the smooth walled portion of the right atrium from the rough-walled portion?
Sulcus terminalis
This part of the right atrium runs parallel to sulcus terminalis and marks the boundary between the sinus venarum and atrium proper
Crista terminalis
This part of the atrium helps in efficient contraction of the atrium
Musculi pectinati
This part of the atrium represents the remnant of the foramen ovale in a fortis
Fossa ovalis
