Aristotle thought that the reason why when your voice deepened as you got older was because your testes were attached to your larynx, and they pulled it down. It's just more prominent in males generally, right? Yeah, because testosterone makes it bigger. Just underneath the laryngeal prominence, do you know what that little... Cryothyroid membrane is? Is anything clinically important about that? Well, they sometimes use that as an emergency airway. If you have an obstruction above, so something's sitting on the cords, and the cords are closed, they sometimes will go in that particular membrane to put an airway in.
