Question

In the Cardiac Muscles, the Heart Beat is controlled by Non-Contractile Cells in the Heart which are known as:

• A. Purkinje Fibers
• B. Sinoatrial Node
• C. Atrioventricular Node
• D. Septum

Hint:

The Purkinje fibers are part of the cardiac conduction system, crucial for spreading impulses to the ventricles for efficient contraction.

Answer 1

The Correct Option is A

Purkinje fibers are specialized non-contractile cells in the heart that help conduct electrical impulses to ensure coordinated contractions of the ventricles. While the SA Node is the primary pacemaker, Purkinje fibers play a critical role in the conduction system, distributing impulses across the ventricles to regulate the heartbeat.
