The Cardiovascular System Layers of the Heart. The wall of the heart has three layers: the outer epicardium ( epi - = on, upon; cardia = heart), the middle myocardium ( myo - = muscle), and the inner endocardium ( endo - = within, inward). The epicardium is the visceral layer of the pericardium . The majority of the heart is myocardium or cardiac muscle tissue.

Anatomy of the Heart: Pericardium The pericardium has several functions: The pericardium is divided into three layers: 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 pericardial membranes. Pericarditis is a disorder of the pericardium in which the pericardium becomes swollen or inflamed. Some causes of pericarditis include bacterial or viral infections, cancer, and hear attack.

Layers of the Heart The epicardium is the layer of muscle found covering the external surfaces of the heart. It is directly fused with the myocardium internally and is in contact with the serous layer of the pericardium. It is sometimes considered as a division of the inner layer of the pericardium.

Pericardium Visceral layer of serous pericardium: This layer is closely applied to the heart and is often called the epicardium. There exists a slit like space between the parietal and visceral layers of serous pericardium.This space is known as pericardial cavity and it contains a small amount of tissue fluid called pericardial fluid. Pericardial fluid acts as a lubricant to facilitate the movements of heart.isceral layer of serous pericardium: This layer is closely applied to the heart and is often called the epicardium.

Pericardial fluid Function [edit]. The pericardial fluid reduces friction within the pericardium by lubricating the epicardial surface allowing the membranes to glide over each other with each heart beat.

What is the Visceral Pericardium? Parietal pericardium: The outer layer of the pericardium which is a conical sac of fibrous tissue that surrounds the heart and the roots of the great blood vessels.his small amount of fluid, the pericardial fluid, acts as a lubricant to allow normal heart movement within the chest. The word pericardium means around the heart. The inner part of the pericardium that closely envelops the heart is called the visceral pericardium or epicardium.

Section 8: Cardiovascular System (3) The epicardium (the outermost layer) is covered by a reflection of the mesothelial-lined (serous or visceral) pericardium, contains coronary blood vessels and nerves, and corresponds to the tunica adventitia of blood vessels (Plates 149 and 152).

- Temporary Epicardial Pacing: Both single chamber and dual chamber sequential pacing are routinely used in the postoperative period. Temporary epicardial pacing wires are inserted onto the outer surface of the atria or the ventricles during cardiac surgery.. Check all equipment in bed area prior to receiving a patient from theatre 3. Obtain a pacing box either single chamber (figure 2) or dual chamber (figure 3) depending on patients needs. 4. Check box is not damaged and that battery is charged, and that all leads are intact to the box 5.

Pericardium When the visceral layer comes into contact with heart (not the great vessels) it is known as the epicardium. The epicardium is the layer immediately outside of the heart muscle proper (the myocardium). The epicardium is largely made of connective tissue and functions as a protective layer. transverse section of the thorax, showing the contents of the middle and the posterior mediastinum. The pleural cavity and the pericardial cavity are exaggerated since normally there is no space between the pleurae or between the pericardium and heart. Pericardium is also known as cardiac epidermis.

Myocardium of the Heart The myocardium is surrounded by the epicardium (outer layer of the wall of the heart) and the endocardium (inner layer of the heart). Myocardium stimulates heart contractions to pump blood from the ventricles and relaxes the heart to allow the atria to receive blood.

Pericardium - definition and function What is Pericardium, definition and function. Pericardium is a tough, two-layer membranous sac that encloses the HEART. The pericardium’s fibrous outer layer, called the fibrous pericardium, protects the heart from contact with the chest wall and other structures in the chest, including the LUNGS and the sternum.ts two surfaces are the parietal pericardium, which contacts the fibrous pericardium, and the epicardium, which covers the MYOCARDIUM somewhat like a wet tissue. Inside the envelope is a watery fluid that lubricates the heart.

8 Maknaes Who You Canât Believe Are the Youngest T-ARA‘s Jiyeon. You can’t really tell based on appearance who is the maknae of T-ARA if you’re new to the group. Most people would probably guess Boram since she is the youngest-looking and shortest member, but in fact, Jiyeon is the baby of the group. It’s even harder to believe that she’s only 21 (22 in Korean age).

What Is the Function of the Myocardium? What is the function of the myocardium? A: According to About.com, the primary function of the myocardium is to stimulate heart contractions and relaxation. Contractions of the heart allow pumping of blood from the ventricles, and relaxation makes it possible for the atria to receive blood.

Pericardium The pericardium is a tough double layered fibroserous sac which covers the heart. The space between the two layers of serous pericardium (see below), the pericardial cavity, is filled with serous fluid which protects the heart from any kind of external jerk or shock.he serous pericardium, in turn, is divided into two layers, the parietal pericardium, which is fused to and inseparable from the fibrous pericardium, and the visceral pericardium, which is part of the epicardium. Both of these layers function in lubricating the heart to prevent friction during heart activity.

How it's performed Epicardial implantation. Epicardial implantation is an alternative and less widely used method of fitting a pacemaker. In this method, the pacing lead or leads are attached to the outer surface of your heart (epicardium) through an incision in your abdomen (below the chest).Epicardial implantation is often used in children and people who have heart surgery at the same time as the pacemaker implantation.he procedure usually takes about an hour, but it may take longer if you're having a biventricular pacemaker (with three leads) fitted or other heart surgery at the same time. You will usually need to stay in hospital overnight and have a day’s rest after the procedure.
