Does heartbeat depend on the brain?
1 Answer
The heart controls its own contraction independently of the brain
Explanation:
The heart is not dependent on the brain to beat. The heart generates its own action potentials for its muscles.
In normal situations the SA (sinoatrial)node generates the action potentials for the contraction of the heart.
When the frog dies, all signals from the brain stop. The heart of the frog, however, will still contract as the SA node keeps working as the pacemaker
