The double-layered membrane surrounding the heart is called the pericardium. The pericardium is a thick, membranous sac that secretes a lubricating liquid. There is a thin inner layer that sits directly on and is attached to the surface of the heart, called the epicardium. There is a very small space, which usually has a very small amount of fluid, called the pericardial space, and a tough outer layer called the pericardium (peri = around and cardium = heart).
Epicardium is the outer layer of heart tissue. When considered as part of the pericardium, it is the inner layer, continuous with the serial layer.
Yes, the prefix in the word epicardium, epi- means outer, which in this case is the outer layer of the heart.
the epidermis is the outer layer it is a tissue
The three main tissues in the heart are the myocardium (muscular tissue responsible for pumping blood), endocardium (inner lining of the heart chambers), and epicardium (outer layer of the heart).
Connective Tissue
The pericardium. It is composed of two layers: the fibrous pericardium (the outer layer that is made of tough connective tissue) and the serous pericardium (the inner layer in which serous fluid provides lubrication for the heart to beat with almost no friction).
The epicardium is a layer of the heart's outer wall that is primarily composed of connective tissue, rather than fat or nerve tissue. It serves as a protective covering for the heart and contains blood vessels, lymphatics, and nerve fibers.
The wall of the heart is made up of three layers: the epicardium (outer layer), the myocardium (middle layer made of muscle tissue), and the endocardium (inner layer lining the chambers of the heart). These layers work together to enable the heart to efficiently pump blood throughout the body.
Xylem
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.
The tissue under the outer layer has many, many nerve endings which are very touchy.
