Is the Serosa the same as the visceral peritoneum?
Serosa thus is the same as visceral peritoneum. a structure with a serosa = a structure that is lined by visceral peritoneum. a structure with an adventitia = a structure that is NOT lined by visceral peritoneum, (but instead is surrounded by connective tissue fixed to it).
Is the uterus in the peritoneum?
The body of the uterus is surrounded by peritoneum, hence it lies intraperitoneal. The kidneys, and the large vessels – the aorta and the inferior vena cava- lie posterior to the peritoneal cavity: retroperitoneal. Several pelvic organs lie inferior to the peritoneum: subperitoneal.
What is the visceral Serosa?
Visceral Serosa. Serous membrane that covers external surface of organs within the cavities. Pleura. Covering of the lungs and thoracic cavity that is moistened with serous fluid to reduce friction during respiratory movements of the lungs.
What is another name for the visceral pericardium?
epicardium
What is visceral pericardium?
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.
Where is visceral pericardium found?
The visceral serous pericardium, also known as the epicardium, covers the myocardium of the heart and can be considered its serosa. It is largely made of a mesothelium overlying some elastin-rich loose connective tissue.
What is the visceral pericardium made of?
The visceral pericardium or epicardium is composed of a single layer of serosal investment covering the entire heart (thin red line overlying the myocardium in blue). Note that the serosal lining of the parietal and visceral pericardium is a continuous layer of mesothelial cells.
What does visceral layer mean?
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.
What is the visceral pleura?
Visceral pleura covers the surfaces of both lungs and forms interlobar fissures that may be complete or incomplete in their extension to the hila. Parietal pleura lines both thoracic cavities and may be designated by its location as costal, diaphragmatic, or mediastinal pleurae.
What does the term visceral mean?
Visceral: Referring to the viscera, the internal organs of the body, specifically those within the chest (as the heart or lungs) or abdomen (as the liver, pancreas or intestines). In a figurative sense, something “visceral” is felt “deep down.” It is a “gut feeling.”
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 difference between visceral pericardium and epicardium?
Visceral pericardium envelopes the heart and forms epicardium – the most superficial layer of the heart. Two layers of pericardium form the sac with the heart suspended in it by the aorta, pulmonary arteries, and pulmonary veins. Pericardial sac normally contains clear, straw-colored fluid called pericardial fluid.
Why is pericardium so important?
The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.
What is called pericardium?
The pericardium is a thin sac that surrounds your heart. It protects and lubricates your heart and keeps it in place within your chest. Problems can occur when the pericardium becomes enflamed or fills with fluid.
What are pericardial layers?
The pericardium consists of two layers: the fibrous and the serous. The fibrous pericardium is a conical-shaped sac. Its apex is fused with the roots of the great vessels at the base of the heart.
What is in between the two layers of pericardium?
The inner (visceral) layer of the serous pericardium lines the outer surface of the heart itself. Between the two layers of the serous pericardium is the pericardial cavity, which contains pericardial fluid. It is this fluid that provides lubrication between the two layers, and allows the heart to expand and contract.
What is the deepest layer of the pericardium?
From superficial to deep, these are the epicardium, the myocardium, and the endocardium. The outermost layer of the wall of the heart is also the innermost layer of the pericardium, the epicardium, or the visceral pericardium discussed earlier.
Where is pericardium attached?
