Question

What do the Purkinje fibres connect to?

Answer 1

Purkinje fibres:

1. These are associated with the ends of the bundle forming a network on the endocardial surface of both the ventricles.
2. These Purkinje fibres are less intense towards the base of the ventricles.
3. Only the papillary muscle tips penetrate the inner third of the endocardium.
4. It seems to be more resistant to ischemia compared to normal myocardial fibres.
5. In the conducting system of the heart, Purkinje fibres arise from the bundle of His and spread into both the ventricles carrying the impulses to the muscles of the ventricles and causing ventricular systole.
