Conclusion:
a) The heart is said to be 'self-excitable'. It generates its own contractions without
having to be commanded to do so by the brain. This is achieved by the action of
natural pacemakers in the heart - nodes of tissue that start the electrical impulses to
get the heart to beat.
What is the name of the natural pacemaker that starts the heartbeat?
Where is it found?
