Larynx
The larynx /ˈlærɪŋks/ (plural larynges; from the Greek λάρυγξ lárynx), commonly called the voice box, is an organ in the neck of amphibians, reptiles, and mammals involved in breathing, sound production, and protecting the trachea against food aspiration. It manipulates pitch and volume. The larynx houses the vocal folds (vocal cords), which are essential for phonation. The vocal folds are situated just below where the tract of the pharynx splits into the trachea and the oesophagus.

Cartilages
There are nine cartilages, three unpaired and three paired, that support the mammalian larynx and form its skeleton.

RAE Larynx
The Royal Aircraft Establishment Larynx (from "Long Range Gun with Lynx engine") was an early British pilotless aircraft, to be used as a guided anti-ship weapon. Started in September 1925, it was an early cruise missile guided by an autopilot.
A small monoplane powered by a 200 hp Armstrong Siddeley Lynx IV engine, it had a top speed of 200 mph (320 km/h); faster than contemporary fighters.
It used autopilot principles developed by Professor Archibald Low and already used in the Ruston Proctor AT, a radio controlled biplane that was intended to be used against German Zeppelin bombers.
