Document Summary

Covers the heart and the great vessel roots. Composed of 2 layers: fibrous pericardium continues with central tendon of the diaphragm (outer, serous pericardium. Serous pericardium: a single layer of serous membrane. Continuous serous membrane but divided based on where it lines: parietal = fibrous pericardium sac, visceral = surface of heart. Pericardial cavity: a potential space b/w the parietal and visceral layers of serous pericardium, contains a small amount of fluid, providing a frictionless environment. During development, the heart undergoes a 45 degree rotation towards the left -> right chambers in front and left on back atria on right and ventricle in left. Atrium appendage (auricle: projects towards front of heart at the root of the great vessels. Sulcus (groove: anterior atrioventricular (coronary) sulcus, b/w right atrium and right ventricle, turns to the back of the heart once it reaches the inferior border-> becomes the posterior as. Interventricular sulcus: b/w right ventricle + left ventricle, anterior and posterior.
