If you are moving the only freely moving bone in the skull, what activity are you doing and what bone are you moving?

This question wants to know if you're moving the only freely movable bone in your skull, what are you doing and what bone is it? Well, the only freely moving bone in my skull is my jaw or my mandible. And if I'm you moving that, then I'm either singing or talking or eating, something like that. So let's see if that's an option. Looky loo. I can see b here chewing with the mandible. I'm giving that one the green checkaroo, but let's see our other options. Well, all these other options, the palatine bone, that makes up the back of the roof of my mouth at the back of my palate, but it doesn't move. So when I that bone does not move. We have crying. We have the lacrimal bone. Well, the lacrimal bone is on the inside of my eye right where those tear ducts are. Tear ducts are called the lacrimal ducts. But again, the bone doesn't move, so it's not going to be that one. I have sneezing with the ethmoid bone. Well, the ethmoid bone makes up a lot of that nasal cavity. So when I sneeze, a lot of air goes through it, but the bone shouldn't move. You better hope it's not moving. If it does, there's something really wrong with you. So it's not that one. So I feel very comfortable saying that the only movable bone in the skull is the mandible. And if I'm moving it, there's a good chance I'm chewing.
