How can I stick out my tongue?

If muscles can only contract, (e.g. both biceps and triceps are needed to lever your forearms up and down) then how can I swell up my tongue and have it protrude from my mouth? Is it pulled forward from my throat? The control ‘sensation’ seems to lie inside the top surface of the organ. It doesn’t seem as simple as making the organ into a smaller cross-section for the same volume, and it seems to respond too quickly to be a hydro-static thing.

In: Biology

Your tongue actually has eight muscles, not one. One of those is attached to the front of your lower jaw, and pulls the whole lot forward.

Edit: grammar

Pretend like you are throwing up, it’s the same muscles, you’ll figure it out once you do that a few times.
