As a retired registered nurse, having worked primarily in CCU units in hospitals, I have found that most people do not understand the different types of "heart trouble" that exists, so I offer examples of three common types that exist for those who have cardiac disease.
of the cardiac conduction system. Labels for aorta, right and left atrium, right and left ventricles, SA node, AV node, Purkinje fibers, and bundle branches.
Purkinje fibers differ in numerous ways from working cardiomyocytes. In general, Purkinje cells are larger than cardiomyocytes and are distinguishable histologically. The transverse tubules that are present in cardiomyocytes are absent in Purkinje cells. The primary role of Purkinje cells is rapid conduction of the electrical impulse. Definition of Purkinje fiber : any of the modified cardiac muscle fibers with few nuclei, granulated central cytoplasm, and sparse peripheral striations that make up a network of myocardial conducting tissue First Known Use of Purkinje fiber circa 1890, in the meaning defined above Named after Jan Evangelista Purkinje (Czech Purkyně) (1787–1869), Czech physiologist, who discovered the fibers in 1839 Words nearby Purkinje fiber Puritanism, Puritans, Puritan spoon, purity, Purkinje cell, Purkinje fiber, Purkinje layer, Purkinje's figures, Purkinje shift, purl, purler Purkinje fibers are widely distributed in FTs, which connected the endocardial Purkinje fibers to the Purkinje fibers of papillary muscles or adjacent endocardium. The electrophysiological characteristics of Purkinje fibers contained in FT were similar to the Purkinje fibers on endocardium.

En fiber extender blir extremt snabb. Upplevelsen blir som om man satt direkt vid den dator eller server man vill kontrollera. Är avståndet stort är fiber lösningen. Idag finns det fiberextender till mycket rimlig kostnad. En överförning via fiber sker mycket snabbt, säkert, i princip avbrottsfritt samt med en enorm kapacitet.
Purkinje fibers from dogs and sheep are the most frequently used; however, fibers have also been obtained from other animals such as calves, pigs, goats, and rabbits. The number of usable fibers varies with each heart, and in the dog ranges from three to eight.

Purkinje Fibers. Purkinjetrådar. Engelsk definition. Modified cardiac muscle fibers composing the terminal portion of the heart conduction system. Svenska
Description. The Purkinje fibers (Purkyne tissue or subendocardial branches) are located in the inner ventricular walls of the heart, just beneath the endocardium When a cardiac Purkinje fiber is exposed to 20 mM Cs the membrane potential falls to about −60 mV within 1 min.
parallel fiber to Purkinje cell synapse. An excitatory synapse formed by the parallel fibers of granule cells synapsing onto the dendrites of Purkinje cells.
fiber is in all plant foods, including fruits, vegetables, grains, nuts, seeds, and legumes.
