hjertemuskelfiberen
Hjertemuskelfiberen, also known as cardiac muscle fiber, refers to the individual muscle cells that compose the myocardium, the muscular tissue of the heart. These fibers are specialized for continuous, rhythmic contraction, enabling the heart to pump blood effectively throughout the circulatory system.
Cardiac muscle fibers are characterized by their striated appearance, similar to skeletal muscle, due to the
The fibers are branched in structure, which allows for a high degree of connectivity and uniform contraction.
Metabolically, cardiac fibers are highly adaptable, capable of utilizing various energy substrates including fatty acids, glucose,
The unique properties of hjertemuskelfiberen allow the heart to perform its vital function of circulating blood
