Which part of the heart is known as the bundle of His?
A) AV bundle
B) SA bundle
C) Mitral valve
D) Bicuspid valve
Bundle Of His
A collection of heart muscle cells specialized for electrical conduction that transmits electrical impulses from the atrioventricular node to the ventricles of the heart.
AV Bundle
The atrioventricular bundle, or Bundle of His, is a collection of heart muscle cells specialized for electrical conduction that transmits the electrical impulses from the AV node to the point of the apex of the fascicular branches.
Bicuspid Valve
The heart valve located between the left atrium and left ventricle that controls blood flow and consists of two flaps; also known as the mitral valve.

Final Answer :
A
Explanation :
The bundle of His, also known as the atrioventricular (AV) bundle, is a collection of specialized muscle fibers located in the septum of the heart. These fibers are responsible for transmitting electrical impulses from the atrioventricular node (AV node) to the Purkinje fibers, which then carry the signal to the ventricles and cause them to contract. The SA bundle, mitral valve, and bicuspid valve are not related to the bundle of His.
