Cardiac muscle cells or cardiomyocytes (also known as cardiac myocytes) are the muscle cells (myocytes) that make up the heart muscle. Cardiomyocytes go through a contraction-relaxation cycle that enables cardiac muscles to pump blood throughout the body.

2023年7月30日 · Cardiac muscle cells (cardiomyocytes) are striated, branched, contain many mitochondria, and are under involuntary control. Each myocyte contains a single, centrally located nucleus surrounded by a cell membrane known as the sarcolemma.

Also known as myocardiocytes, cardiomyocytes are cells that make up the heart muscle/cardiac muscle. As the chief cell type of the heart, cardiac cells are primarily involved in the contractile function of the heart that enables the pumping of blood around the body.

2020年9月24日 · Cardiomyocytes are the most prevalent cardiac cells and comprise higher percentages in ventricles than atria, and in female versus male ventricular tissues.

2005年9月1日 · Cardiomyocytes are the cells responsible for generating contractile force in the intact heart. Specialized cardiomyocytes form the cardiac conduction system, responsible for control of rhythmic beating of the heart.

2023年8月8日 · Cardiomyocytes are the individual cells that make up the cardiac muscle. The primary function of cardiomyocytes is to contract, which generates the pressure needed to pump blood through the circulatory system.

The cardiac myocyte is a specialized striated muscle cell that is approximately 25 μ in diameter and about 100 μ in length. They form a branching network of cells that are connected by intercalated discs. The myocyte is composed of bundles of myofibrils that contain myofilaments.

Myocytes constitute the majority of the heart by mass and have been shown to be major contributors to contractile dysfunction. We discuss various approaches that have been used to study myocyte cell biology in the setting of heart disease and cover recent advances.

The heart is the first formed organ in the developing fetus. During fetal and postnatal development cardiomyocytes become terminally differentiated muscular cells that are connected end to end by gap junctions, allowing concerted contractile activity.

2021年4月16日 · Types of cardiomyocytes. There are three main types of cardiomyocytes: Contractile cardiomyocytes: these are the ordinary cardiomyocytes that form the majority of the myocardium of the atria and ventricles. Their main function is contraction. Endocrine cardiomyocytes: these are cardiomyocytes that have an endocrine function.
