Pericardium, visceral: The double inner layer of the pericardium. One layer of the visceral pericardium closely adheres to the heart, and the other lines the inner surface of the outer (parietal) pericardium. The intervening space is filled with pericardial fluid. Also known as epicardium.
Is pericardium the same as visceral pericardium?
The word "pericardium" means around the heart. The outer layer of the pericardium is called the parietal pericardium. The inner part of the pericardium that closely envelops the heart is, as stated, the epicardium; it is also called the visceral pericardium.

What is the pericardium?
The pericardium is a thin, two-layered, fluid-filled sac that covers the outer surface of the heart. It provides lubrication for the heart, shields the heart from infection and malignancy, and contains the heart in the chest wall.
What is the visceral layer of the serous pericardium?
The visceral layer, or epicardium, covers the heart and the great vessels, and from the latter is continuous with the parietal layer which lines the fibrous pericardium. The portion which covers the vessels is arranged in the form of two tubes.

Parietal pericardium receives general sensory innervation from the phrenic nerve; visceral pericardium receives visceral sensory innervation from sympathetic nerves (to T1–T4 spinal cord levels) and vagus nerves (to medulla oblongata).
What is a visceral layer?

Where is the visceral pericardium located?
The visceral pericardium is located directly on the heart itself.
What is the difference between the visceral and parietal pericardium?
The key difference between visceral pericardium and parietal pericardium is, the visceral pericardium is the inner layer of the serous pericardium that outlines the outer layer of the heart's epicardium while the parietal pericardium is the outer layer of the serous pericardium that outlines internal surface of the ...
What is the function of the visceral pericardium?
Visceral pericardium is both the inner layer of the pericardium and the outer layer of the heart wall. Also known as the epicardium, this layer protects the inner heart layers and also assists in the production of pericardial fluid.
What is the visceral pericardium quizlet?
The visceral pericardium (epicardium), covers the heart. ... The wall of the heart is composed of three distinct layers: an outer epicardium, a middle myocardium, and an inner endocardium. The epicardium, which corresponds to the visceral pericardium, protects the heart by reducing friction.
Is the visceral pericardium a serous membrane?

What is the difference between parietal and visceral?
The serous membrane that covers internal organs is called a visceral membrane; while the one that covers the cavity wall is called the parietal membrane.
What is the structure of pericardium?
Normal pericardium consists of an outer sac called fibrous pericardium and an inner one called serous pericardium. The two layers of serous pericardium: visceral and parietal are separated by the pericardial cavity, which contains 20 to 60 mL of the plasma ultrafiltrate.
Is the parietal pleura a visceral membrane?
Pleurae are serous membranes that separate the lungs and the wall of the thoracic cavity. The visceral pleura covers the surface of the lungs, and the parietal pleura covers the inside of the thorax, mediastinum, and diaphragm.

The pericardium is a dual-layered structure enveloping the heart and proximal great vessels. It consists of an inner visceral pericardium (also called the epicardium when in contact with the myocardium), and an outer parietal pericardium, composed of layers of collagen fibrils and elastin fibers.
What fluid is in the pericardium?
Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an outer fibrous layer and the inner serous layer.
Is visceral inner or outer layer?
The inner layer (visceral pleura) wraps around the lungs and is stuck so tightly to the lungs that it cannot be peeled off. The outer layer (parietal pleura) lines the inside of the chest wall. The very thin space between the layers is called the pleural cavity.
