Learning a little Latin helped me to remember:
- "visceral" refers to inner
- "pari" = wall
- "peri" = around
- "epi" = upon
- "endo" = inside
- "myo" = muscle
Most people think of the pericardium as just a double-layered, membranous sac (The Pericardial Cavity) that is around the heart. But, the pericardium is actually TRIPLE layered: the visceral layer, the parietal layer, and the fibrous layer (fibrosa).
The visceral pericardium is the inner-most layer of the pericardium, and is also known as the Epicardium as it "lays" upon the heart.
The Pericardial Cavity lies between the visceral pericardium and the parietal pericardium. This cavity is filled with pericardial fluid which serves as a shock absorber by reducing friction between the visceral and parietal layers. The parietal pericardium is an outer layering wall of the Pericardial Cavity between the pericardial membranes.
The outer-most layer is the fibrous layer (fibrosa), and contains nerves, blood vessels, and lymphatics. This is the layer that can become inflamed, called pericarditis. (As opposed to, endocarditis, which is inflammation of the insidelayer of the heart.)
Parietal refers to the outer layer of a body cavity, such as the parietal pleura lining the chest cavity. Visceral refers to the inner layer of the same body cavity, like the visceral pleura covering the lungs. These terms are commonly used in anatomy to describe the different layers surrounding organs and cavities within the body.
the parietal membrane is superficial to the parietal membrane (ie closer to the skin) these membranes cover various structures in the body such as the lungs where the space in between forms the pleural cavity.
Visceral has to do with organs and parietal has to do with the body cavity. The visceral membrane lines the internal organ, whereas the parietal membrane lines the body cavity.

Is the visceral pleura superficial to the parietal pleura?
No, the parietal pleura is superficial to the visceral pleura. The parietal pleura lines the inner surface of the thoracic cavity, while the visceral pleura covers the surface of the lungs.
WHAT is the difference between visceral and parietal serous membrane?
Visceral serous membranes line organs. Parietal serous membranes line cavities.
What is the Innervation of visceral and parietal pleura?
The visceral pleura is innervated by autonomic nerves that travel with the bronchial blood vessels. The parietal pleura is innervated by somatic nerves, specifically the intercostal nerves and the phrenic nerve.
What membrane reduction of friction between the parietal and visceral surfaces?
Serous Membranes
What is the protective membrane covering of the heart called?
parietal layer
Is the visceral pleura superficial to the parietal pleura?
No, the parietal pleura is superficial to the visceral pleura. The parietal pleura lines the inner surface of the thoracic cavity, while the visceral pleura covers the surface of the lungs.
The parietal pleura is an example of a visceral membrane?
The parietal pleura is actually an example of a parietal membrane, not a visceral membrane. Visceral membranes cover organs, while parietal membranes line body cavities. In the case of the pleura, the parietal pleura lines the chest cavity and the visceral pleura covers the lungs.
Has parietal and visceral layers?
Parietal membrane is the lining of a body cavity. Visceral membrane is the covering of each organ in a body cavity.
WHAT is the difference between visceral and parietal serous membrane?
Visceral serous membranes line organs. Parietal serous membranes line cavities.
What membrane is constructed of a visceral and parietal layer?
The pericardium is the membrane that is constructed of a visceral and parietal layer. The visceral layer is in direct contact with the heart, while the parietal layer lines the outer surface of the pericardial sac. This double-layered membrane protects and lubricates the heart.
What separates the parietal and visceral pericardium?
pericardial cavity
Which membrane has parietal and visceral layers?
serous pericardium.
What membrane has parietal and visceral layer?
The serous membrane has parietal and visceral layers. The parietal layer lines the body cavity, while the visceral layer surrounds and covers internal organs. This double-layered structure reduces friction as organs move within the body.
Name and describes the two layers of the pleura?
Visceral and parietal visceral- covers the lungs, thin serous membrane parietal- lines the inner chest wall and covers diaphram
What is the Innervation of visceral and parietal pleura?
The visceral pleura is innervated by autonomic nerves that travel with the bronchial blood vessels. The parietal pleura is innervated by somatic nerves, specifically the intercostal nerves and the phrenic nerve.
How many layers does the parietal pericardium have?
2; Visceral and the Serous
What is the innermost layer of the pleura known as?
Visceral pleura. The parietal pleura surrounds the outside of the lung. When you are dissecting, the parietal pleura is the layer of lung that you remove. It is difficult to remove the visceral pleura, but not impossible.
