Question

multiple choice question
the space between the epicardium (visceral pericardium) and parietal pericardium is called the

subcardiac space
pericardial cavity
endocardial cavity
fibrous pericardium

Explanation:

The pericardium has two layers - the parietal pericardium and the visceral pericardium (epicardium). The space between these two layers is filled with pericardial fluid and is specifically termed the pericardial cavity. The subcardiac space is not a standard anatomical term in this context. The endocardial cavity refers to the inner lining of the heart chambers (endocardium) and the space within the heart, not the space between the pericardial layers. The fibrous pericardium is the tough outer layer of the pericardium, not a space.

Answer:

pericardial cavity
