Arytenoid
Arytenoid
Arytenoid (pronounced: /ˌarɪˈtiːnɔɪd/) is a term used in anatomy to refer to a pair of small three-sided pyramids which form part of the larynx, to which the vocal cords are attached. They are situated at the back of the larynx and are responsible for opening and closing the vocal cords, thus controlling the production of sound.
Etymology
The term "arytenoid" is derived from the Greek words "arytaina" meaning ladle, and "eidos" meaning form or shape. This is due to the ladle-like shape of the arytenoid cartilages.
