What is the difference between the Visceral Pericardium and the Epicardium?
They are the same.
What are the layers of tissue that make up the pericardium?
Fibrous pericardium and serous pericardium. The serous pericardium is made up of an outer parietal layer that is fused to the fibrous pericardium and an inner visceral layer (aka epicardium) that is a layer of the heart wall and adheres tightly to the heart.
Space between the epicardium and the parietal pericardium?
pericardial cavity
The outer covering of the heart?
The heart is encased in two protective layers. The outer layer -- the pericardium -- covers the heart. It folds in on itself at the aorta forming the epicardium of the heart. Between these layers is a small amount of fluid (10-50 ml) that affords the layers a non-stick surface.
What is the space between the epicardium and the parietal pericardium?
The pericardial sac.
What region is the pericardial cavity?
The pericardial space lies between the pericardium and the epicardium.
Is visceral pericardium deep to the parietal pericardium?
Yes, the visceral pericardium adheres to the outside surface of the myocardium (heart muscle), while the parietal pericardium lies outside of the visceral pericardium. There is a small amount of lubricating fluid between these two membranes in the potential space known as the pericardial space. If an abnormal amount of fluid of any kind builds up in this space, it is called a pericardial effusion.
What are the layers of the heart wall from superficial to deep?
The heart consists of three tissue layers: endocardium, myocardium, and pericardium. The endocardium, the innermost layer, lines the hearts chambers and is bathed in blood. The myocardium is the thick middle layer of the heart. Its cells are unique in that they physically resemble skeletal muscle but have electrical properties similar to smooth muscle. These cells also contain specialized structures that help to rapidly conduct electrical impulses from one muscle cell to another, enabling the heart to contract. The pericardium is a protective sac surrounding the heart, which consists of two parts: the inner serous pericardium and the outer fibrous pericardium. The serous pericardium has two layers--the visceral and the parietal. The visceral pericardium, also called the epicardium, is the inner layer, in contact with the heart muscle itself. The parietal pericardium is the outer, fibrous layer. In the pericardial cavity, between these two layers, is about 25 milliliters of pericardial fluid, a lubricant that reduces friction as the heart beats and changes position. The fibrous pericardium encases the serous pericardium. It is made of dense connective tissue and is attached to both the diaphragm and the base of the great vessels.
What is parietal and visceral?
(1) On February 8, 2012 at 5:57 am Mysandie [0] said:Learning a little Latin helped me to remember:"visceral" refers to inner"pari" = wall"peri" = around"epi" = upon"endo" = inside"myo" = muscleMost 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.)
Where is the cardiac located?
A thin, slippery, double membrane, which is called the pericardium, surrounds the heart and lines the chest wall. The inner membrane is the visceral pericardium which covers the surface of the heart, and the outer membrane is the parietal pericardium which lines the chest wall. Between the membranes is a small amount of lubricating fluid to reduce friction during the heart's movements.(note: previous answer mentioned sinovial fluid, which incorrect, as it is found in joints and not around the heart)Reference used for above info: Page 18; Principals of Anatomy and Physiology, 12th Ed.; TorTora and Derrickson; John Wiley and Sons, Inc.
What is the fluid sac that surrounds the heart?
Yes, it is.
Where is the myocardium located in the heart?
The myocardium is located between the endocardium and the visceral layer of the serous membrane (epicardium) of the heart.
