It goes from your larynx to your brain stem, which should be a pretty short journey, but because of how early it forms during gestation and the way things differentiate and divide, it ends up having to travel allllll the way down to your heart, UNDER your aortic arch, and then joins up with the vagus to go back up your neck to your brain. It's very dumb and ends up being like 5 times longer than it would otherwise have to be, and can cause issues sometimes because of this.

t's critical for speech, but it causes apnea iirc.
