Answer:
bundle of his is a network of muscle fibres found only in the ventricle wall
'Bundle of His' is a network of muscle fibres found only in the ventricle wall.
It's called by this name due to the following reasons :
- In 1983 'Bundle of His' was discovered by Wilhem His Jr who discovered it to be an important and specialized tissue in the heart which transmits electrical impulse and also helps in the contraction process.
- It's located in the region of anterior-inferior end of the inter-atrial septum , corresponding to the ventricles of the heart.
- These are special kind of muscle fibres which are also known as Purkinje fibres.
- They play a very important role in transmitting the impulse from the atrio-ventricular node to all the other basic parts of the body.
