Difference between Bundle of His and Purkinje Fibres
The difference between Bundle of His and Purkinje Fibres are stated below:
|
Features |
Bundle of His |
Purkinje Fibres |
|---|---|---|
|
Location |
It is located in wall between two ventricles( Inter ventricular septum). |
It is located in the interventricular septum and spread throughout the ventricle. |
|
Discovery |
It was discovered by Wilhelm His Jr. |
It was discovered by Jan Evangelista Purkinje |
|
Composition |
It is made up of purkinje cells, slender and transient cells etc |
It is composed of specialised larger sized cells. |
|
Branches |
Bundle of His is divided into right and left Branches. |
It is not branched but a part of the left branch of His Bundle. |
|
Impulse |
It receives the impulse from the AV node. |
It receives the impulses from the Bundle of His. |
|
Muscle Contraction |
It will not initiate muscle contraction |
It will initiate the contraction of ventricles and help in pumping oxygenated blood to all parts of the body. |
|
Second function |
It does not function directly in heart beat formation. |
This acts as the second pacemaker of the heart. |
|
Speed |
The speed of impulse transmission is slow |
The speed of impulse transmission is very fast. |
Difference Between Bundle of His and Purkinje Fibers
The Difference between Bundle of His and Purkinje Fibres lies in function, structure, and location in the body. The bundle of His and Purkinje fibres are both components of the cardiac conduction system, playing critical roles in the transmission of electrical signals through the heart. Electrical impulses are sent from the AV node to the Purkinje fibres via the bundle of His, which serves as a bridge connecting the atria and ventricles. In this article, we will learn about his and Purkinje fibres’ bundles, function, location, and differences.
