The pericardium is the protective sac surrounding the heart, while the epicardium is the outermost layer of the heart wall, lying directly on the heart.
c) The myocardium of the heart wall is a working muscle formed with smooth involuntary muscle 5.The outer layer of the heart is called the a) myocardium b) endocardium c) epicardium
The human heart is made up of four main chambers: two atria and two ventricles. The two atria (right and left) are located on top of the two ventricles (right and left). The atria are smaller in size than the ventricles. The right atrium receives oxygen-depleted blood from the...

The site of origin of the mammalian heart beat: The pacemaker in the dog Aside from the nerve fibers which enter the pace-making node from the subepicardium, there were observed within the limits of the node a few ganglionic cells and a plexus of moniliform nerve fibrils in very close re...
What is the amount of serous fluid? INTRODUCTION. Normally, a small volume(≈0.25 ml/kg)of serous fluid lies between the outer fibrous (parietal) pericardial layer and the serous visceral pericardium or epicardium. How many serous fluid are there?
In the case when the T wave is formed not by the whole ventricles but by a segment of ventricular wall, the time difference between the earliest and the latest repolarization of epicardium is small as well as apicobasal APD gradient and the difference in activation time between the upper and...
of mRNA-based vaccines for COVID-19 to contain the global pandemic and the investment in billions of US dollars in space exploration projects and the blooming space-tourism industry fueled by the latest reusable space vessels. Now, it is time to examine where the translation of pluripotent stem...
Original cardiac pacing devices utilized epicardial pacing techniques where an extravascular lead was implanted on the epicardium and connected to a pulse generator, originally implanted in the abdomen. Current epicardial pacing systems are used in patients with congenital heart disease, lack of venous ac...
In addition to embryonic FHF and SHF CPCs, other progenitor cell populations, including epicardium-derived cells (EPDCs) and cardiac neural crest cells (cNCCs), also contribute to the formation of the developmental heart.
