Reply to comment by PowerStacheOfTheYear in (Biology) How far down your spine can you break before respiratory impairment? by Anomaly-Friend

what do you think controls the AV node, the SA node, and the Bundle of hiss?? the heart controls itself, or its impulses come from the ANS, which is a sub branch of the CNS, which is the brain and the spinal cord.

Call JAMA, The Lancet, NEJM! They have to know!

Wait you googled SA node and you still think you're not wrong?

Damn, dude.

The brain controls the SA node, but the SA node can function without the brain. There's also a ventricular pacemaker. There's backups to the backups. The heart is an important organ.
