Question

what is purkinje fibre...... ​

Answer 1

Explanation:

The Purkinje fibers are specialised conducting fibers composed of electrically excitable cells that are larger than cardiomyocytes with fewer myofibrils and many mitochondria and which (cells) conduct cardiac action potentials more quickly and efficiently than any other cells in the heart.

Answer 2

$\huge\mathfrak\red{Answer}$

The Purkinje fibers are the terminal part of the cardiac conduction system. They form a three- dimensional subendocardial network originating from the bundle branches and their main function is to distribute the depolarization signal rapidly to the working myocardium.
