Question

How does your tearducts know when to produce tears.

In: Biology

Answer 1

The brain stem controls things like breathing, digestion, and tear production.

There’s a medical condition called anencephaly where babies are born without a brain. Sometimes these babies will show typical baby traits and can breathe, cry, or grab your finger.

These are things we can do without thinking about it.
