Q9 Why do we call our heart myogenic?
Because the cardiac impulse originates in the heart muscles, which is called myogenic. Modified cardiac muscles or the nodal tissue of the heart—the SA node—can generate an impulse which spreads over the walls of the heart.
This results in the beating of the heart.
The meaning of ‘myo’ is ‘muscle’ and ‘genic’ is ‘originating from’.
