The purkinje fibers are located in :
WebbThe purkinje fibres are found in the sub-endocardium. They are larger than cardiac muscle cells, but have fewer myofibrils, lots of glycogen and mitochondria, and no T-tubules. These cells are connected together by desmosomes and gap junctions, but not by intercalated discs. Take a look at this EM of a purkinje cell. WebbThe Purkinje fibres are located in the inner ventricular walls of the heart, just beneath the endocardium in a space, called as the subendocardium. These fibres consist of specialized cardiomyocytes, that are able to conduct cardiac action potentials. So, the correct answer is option A Solve any question of Body Fluids and Circulation with:-
