Which of the following is responsible for conducting electrical impulses within cardiac muscle?

A. Endocardium

B. Purkinje fibers

C. Pericardium

D. Chordae tendineae

the answer is option D.

Explanation:

The Purine Fibers are in charge of the conduction of the electrical driving forces in the heart muscles. They convey the withdrawal driving forces from both right and left package branch to the myocardium of ventricles. They reaction to the electrical release, which happens in the Sinoatrial Nodes.

The correct answer is option B. Purkinje fibers.

The Purkinje Fibers are responsible for the conduction of the electrical impulses in the heart muscles. They carry the contraction impulses from both right and left bundle branch to the myocardium of ventricles. They response to the electrical discharge, which takes place in the SA (Sinoatrial) Nodes.
