• Pericardium
• Heart
– Orientation
– Surfaces of the heart
– Margins and borders
– Cardiac chambers
– Cardiac valves
– Coronary vasculature
• Thoracic Aorta

, Pericardium
• Encloses the heart
• Closed sac with 2 layers
– outer fibrous layer
– inner serous layer
• Outer fibrous pericardium
– Outer layer
– Very strong
– Attaches superiorly to large blood vessels that enter
and leave the heart
– Inferiorly attached to central tendon of diaphragm

, Pericardium
• Inner serous pericardium
– Innermost, thin serous layer divide into 2 layers
• Parietal serous pericardium
• Visceral serous pericardium
– Parietal serous pericardium
• outer layer
• lies closer to the thoracic cage
• Forms outer layer of serous pericardium
• It lines the inside of the outer fibrous pericardium
– Visceral serous pericardium
• surrounds the heart very closely
• inner layer of the serous pericardium and adheres to the cardiac
muscle (myocardium
• known as the epicardium
