Myocardium (muscle tissue heart) - definition and function Myocardium (muscle tissue heart) - definition and function The MUSCLE tissue that forms the walls of the HEART. Myocardial cells are unique in their structure, blending muscle and NERVE structures so they can both contract and conduct electrical impulses. Myocardial cells thus can contract independent of external stimulation. The myocardial fibers of the atria have a different configuration from those of the ventricles.

Myxomatous Myxomatous is the adjective form of the word myxoma. It refers to the formation of a mass of cells in connective tissue. Myxoma is usually found in the mitral valve of the heart, which is located in the left ventricle. Myxomatous degeneration is a phrase used to describe the breaking down of this connective tissue.It can also refer to the development of lesions that resemble myxoma. Another term often used when talking about Myxomatous is mitral valve prolapse.t refers to the formation of a mass of cells in connective tissue. Myxoma is usually found in the mitral valve of the heart, which is located in the left ventricle. Myxomatous degeneration is a phrase used to describe the breaking down of this connective tissue.

- Relevance. Rating Newest Oldest. Best Answer: There are 3 layers of tissue that make up the heart: Myocardium-this is the muscular tissue of the heart endocardium-effectively a specialized endothelium epicardium-a connective tissue layer around the heart. Your best answer is probably muscular tissue though... Source(s):

Muscle tissue An isolated cardiac muscle cell, beating. Cardiac muscle (heart muscle) is involuntary striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium.Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.These three types of muscle all form in the process of myogenesis. The cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, contain only three nuclei.The myocardium is the muscle tissue of the heart, and forms a thick middle layer between the outer epicardium layer and the inner endocardium layer.ardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. These three types of muscle all form in the process of myogenesis. The cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, contain only three nuclei.

Muscle tissue Muscle tissue. Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. It is formed during embryonic development through a process known as myogenesis.

myocarditis Myocarditis is an inflammatory disease of the heart muscle (myocardium) that can result from a variety of causes. While most cases are produced by a viral infection, an inflammation of the heart muscle may also be instigated by toxins, drugs, and hypersensitive immune reactions.

Myocardium Myocardium : muscle tissue of the heart composed of striated, involuntary muscle known as cardiac muscle. Source: CRISP. Myocardium : The muscle tissue of the HEART composed of striated, involuntary muscle known as cardiac muscle. Summary Information: Myocardium. Myocardium: The myocardium is the muscular tissue that makes up the heart, a vital internal organ located in the pericardium in the thorax of the chest. The myocardium is supplied with blood by the coronary arteries. The myocardium is involuntary muscle that is activated by an electrical conductions system.

- From Wikipedia, the free encyclopedia. Myocardium means heart muscle. The heart muscle's job is to push blood out to the entire body. Blood carries oxygen and many other important things to the body. Because every part of the body needs blood to live, the heart muscle is very important to a person's health. The heart muscle can become sick and weak.

Layers of the Heart The myocardium is the middle muscular layer of the heart's walls and it functions by providing a scaffolding for the heart chambers, assisting in contraction and relaxation of the cardiac walls so that blood can pass between the chambers and electrostimulation conduction through its own tissues and into the epicardium.

Types of Cardiac Tissue Endocardium. The endocardium is the name for the interior surface of the heart chambers. Endocardium also covers the heart valves, the one-way passages that allow blood to flow between chambers of the heart. The endocardium consists of endothelial cells, also known as skin cells.

What types of tissues make up your heart? The types of tissues that make up your heart are cardiac muscle tissue, nerve tissue and blood tissue. The cardiac muscle tissue contracts, making the heart pump. The nerve tissue brings messages that tell the heart how fast to beat. The blood tissue is carried from the heart to other organs of the body.

Endocardium The endocardium is the innermost layer of tissue that lines the chambers of the heart.Its cells are embryologically and biologically similar to the endothelial cells that line blood vessels. The endocardium also provides protection to the valves and heart chambers.ecently, it has become evident that the endocardium, which is primarily made up of endothelial cells, controls myocardial function. This modulating role is separate from the homeometric and heterometric regulatory mechanisms that control myocardial contractility.

Cardiac Muscle Tissue Cardiac muscle tissue is an extremely specialized form of muscle tissue that has evolved to pump blood throughout the body. In fact, cardiac muscle is only found in the heart and makes up the bulk of the heart’s mass.ardiac muscle tissue is able to set its own contraction rhythm due to the presence of pacemaker cells that stimulate the other cardiac muscle cells. The pacemaker cells normally receive inputs from the nervous system to increase or decrease the heart rate depending on the body’s needs.

Heart Myocarditis is an inflammation of the myocardium, the middle layer of the heart wall. Myocarditis is usually caused by a viral infection. Signs and symptoms of myocarditis include chest pain, heart failure and abnormal heart rhythms.

- The myocardium is the muscle of the heart. This muscle is supplied by arteries that branch off the aorta. So everytime the heart beats it pushes blood into the aorta and thus … into systemic circulation and thus into the heart wall, as well. These arteries that supply the myocardium are called coronary arteries.

Muscular Tissue Cardiac Muscle Tissue. Cardiac muscle tissue is found only in the heart where cardiac contractions pump blood throughout the body and maintain blood pressure. As with skeletal muscle cardiac muscle is striated, however it is not consciously controlled and so is involuntary.

It is a tough, collagenous sheet that is superficial to the parietal layer of the serous pericardium. The two are separated by a thin layer of amorphous connective tissue.

myocardial myocardial contractility. myocardium has an intrinsic periodic contractility which enables the denervated heart to continue beating; in the intact animal neurogenic control of contractility is paramount, inhibited by parasympathetic effects, stimulated by sympathetic effects.

Cardiac Muscle Tissue Cardiac Muscle Tissue. Cardiac muscle tissue is only found in the heart. Highly coordinated contractions of cardiac muscle pump blood into the vessels of the circulatory system. Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle ([link]). However, cardiac muscle fibers are shorter than skeletal muscle fibers and usually contain only one nucleus, which is located in the central region of the cell.

Cardiac muscle cell Cardiac muscle cells or cardiomyocytes (also known as myocardiocytes or cardiac myocytes) are the muscle cells (myocytes) that make up the cardiac muscle. Each myocardial cell contains myofibrils, which are specialized organelles consisting of long chains of sarcomeres, the fundamental contractile units of muscle cells.Cardiomyocytes show striations similar to those on skeletal muscle cells, but unlike multinucleated skeletal cells, they contain only one nucleus.ach myocardial cell contains myofibrils, which are specialized organelles consisting of long chains of sarcomeres, the fundamental contractile units of muscle cells.
