Fascinating! See what your vocal cords (or larynx) look like when you’re speaking or making sounds. Your larynx is where pitch (musical tones) and volume are controlled. You can also make it louder or more quiet depending on how much air is being pushed out through your lungs!

This is footage from a video laryngoscopy — larynx or voicebox + scope: 

From the University of Iowa Hospitals and Clinics (with permission). This is what happens when I say “eee” with a camera down my throat… Note also that the trachea is visible when I breathe. Cool huh? Actual size: roughly that of a quarter.
