4 paź 2019 · Learn about cardiac muscle, the specialized tissue that forms the heart and pumps blood throughout the body. Find out how cardiac muscle cells are arranged, how they contract, and what proteins are involved in their contraction.
Cardiac muscle cells (also called cardiomyocytes) are the contractile myocytes of the cardiac muscle. The cells are surrounded by an extracellular matrix produced by supporting fibroblast cells. Specialised modified cardiomyocytes known as pacemaker cells, set the rhythm of the heart contractions.
Learn about cardiomyocytes, the muscle cells that make up the heart, and their special features, organelles, and physiology. Find out how cardiomyocytes are involved in heart development, repair, and disease.
30 lip 2023 · 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.
23 lis 2022 · Learn about the characteristics, components, and contraction of cardiac muscle tissue, also known as myocardium, that forms the heart. Find out how cardiomyocytes, intercalated discs, myofibrils, and cardiac conducting cells work together to produce rhythmic contractions.
19 paź 2024 · Cardiac muscle cells form a highly branched cellular network in the heart. They are connected end to end by intercalated disks and are organized into layers of myocardial tissue that are wrapped around the chambers of the heart.
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.
