Your larynx.
A.
The part of the respiratory tract between the pharynx and the trachea, having walls of cartilage and muscle and containing the vocal cords enveloped in folds of mucous membrane.
B.
The modified upper part of the respiratory passage of
air-breathing vertebrates that is bounded above by the glottis, is continuous below with the trachea, has a complex cartilaginous or bony skeleton capable of limited
motion through the action of associated muscles, and in
humans, most other mammals, and a few lower forms has a
set of elastic vocal cords that
play a major role in sound production and speech called also voice box
.
Emcee: "You're all dirty toys with dirty
socks and no choice but to suck. I'll battle all you nerdy boys and the
bitches will flock, I'll crush you and your voice box."
Bystander: yo, my voicebox is sore from the concert. All that cheering and yelling.
