Study Notes
Pericardium
- Double-walled membrane that encases the heart, providing support and protection.
Fibrous Pericardium
- Composed of tough, white fibrous connective tissue.
- Acts as the outer layer of the pericardium, preventing overstretching of the heart.
Serous Pericardium
- A thinner and more delicate membrane encapsulating the heart.
- Forms a double layer, consisting of parietal and visceral layers.
Parietal Layer of Serous
- Lines the internal surface of the fibrous pericardium.
- Provides a smooth surface that facilitates heart movement.
Visceral Layer of Serous
- Directly covers the outer surface of the heart, also known as the epicardium.
- Assists in reducing friction between the heart and surrounding structures during beating.
Pericardial Cavity
- Fluid-filled space located between the parietal and visceral layers of the serous pericardium.
- Contains pericardial fluid, which lubricates the layers, minimizing friction as the heart beats.
