How does crying work? I get that you cry when you reach a certain point of emotion/pain, but how does your brain know it’s enough to cry?

Question

Does it depend on a certain threshold of concentration of chemicals? How does your brain determine that threshold? And what about phisical pain, which is like a signal rather than a chemical?

i believe crying is more of an emotional response to a situation. i don’t think the brain gets involved. maybe i need an ELI4 on this, but
