pericardial cavity
-
fibrous pericardium
-
parietal serous pericardium
-
visceral serous pericardium
-
pericardial sac
-
epicardium
-
endocardium
-
myocardium
Question 2
Question
Functions of pericardium
Answer
-
Facilitation of secure intrathoracic cardiac stability
-
Friction reduction between heart & the mediastinum structures
-
Nutrition of the heart
-
Limitation of cardiac distention and chamber dilation
-
Uniform cardiac distribution of pericardial cavity hydrostatic pressure
-
Formation of a barrier to stop infection
-
Facilitation of atrial filling by promoting negative pericardial pressure during ventricular systole
-
(pericardium + pleural fluid): formation of a system that automatically applies compensating hydrostatic pressures to the cardiac periphery when accelerating forces act

Question 11
Question
-The extensive [blank_start]interatrial groove (of Waterston)[blank_end] separates the two atria.
-The [blank_start]atrio- ventricular (coronary) groove[blank_end] separates the atria from the ventricles and contains the main trunks of the coronary arteries.
-Internally, the ventricles are separated by the septum; its mural margins correspond to the ante- rior and inferior (diaphragmatic) [blank_start]interventricular grooves[blank_end].
Answer
-
interventricular grooves
-
atrio- ventricular (coronary) groove
-
interatrial groove (of Waterston)
Question 12
Question

Answer
-
fifth left
-
midclavicular line
Question 13
Question
The diaphragmatic surface of the heart rests mainly on the [blank_start]central tendon[blank_end] but also, apically, on a small area of the left muscular part of the diaphragm.
Answer
-
central tendon
