Answer 1

Answer:

Hey mate!! here is ur answer hope it helps you...thank me if the answer is crct

Explanation:

The SA node has the inherent capability to generate a wave of contraction and also controls the heartbeat which is why it is termed as the pacemaker. As the heartbeat is triggered by the sinoatrial node, and impulse of contraction originates in the heart, the human heart is known as myogenic.

• In the human heart , contraction is initiated by a special modified heart muscle known as sinoatrial node...Since the heart beat is initiated by SA node and the impulse of contraction originates in the heat itself ,the human heart is termed myogenic .The hearts of vertebrates and molluscs are also myogenic
