Cardiomyocytes (Cardiac Muscle Cells) – Structure, Function, …
Cardiomyocytes are highly specialized cell types in terms of their structures and functions. Each cardiomyocyte contains myofibrils, unique organelles consisting of long chains of sarcomeres, the fundamental contractile units of muscle cells.

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.
Cardiomyocytes (Cardiac Muscle Cells)- Structure, Function
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.

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.
CV Physiology | Cardiac Myocytes and Sarcomeres
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.
The structure and function of the cardiac myocyte: A review of ...
The myocardium is highly organized tissue, composed of several cell types that include smooth muscle cells, fibroblasts, and cardiac myocytes. The fundamental contractile cell of the myocardium is the myocyte.
Cardiomyocytes structure, function and associated pathologies
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.

2024年2月15日 · Cardiomyocytes are structurally connected by intercalated discs which have gap junctions for diffusion and communication. They allow the transmission of contractile force between cells as electrical depolarization propagates from cell to cell, which facilitates a uniformal contracting force.
Histology of the heart, Cardiomyocytes types, Ultrastructure …
2021年4月16日 · Each cardiac muscle fiber is composed of several short columnar cells, cardiomyocytes joined end to end by the intercalated discs that run transversely across the fiber. Each cardiomyocyte has a single, centrally-located oval nucleus.
Cell of the Month: Cardiomyocytes - Tempo Bioscience
2019年8月7日 · Cardiomyocytes are cardiac muscle cells. They are terminally differentiated and facilitate contractile forces (“beatings”) of the heart. Grown in vitro as a monolayer sheath, cardiomyocytes are connected by gap junction proteins that help synchronize contraction-relaxation cycles of the cardiomyocytes.
