The correct spelling for the word describing a paired cartilage structure in the larynx responsible for opening and closing the vocal cords is 'arytenoid cartilage'. The correct pronunciation of the word is /əˈrɪtənɔɪd ˈkɑːtɪlɪdʒ/. The 'aryt' is pronounced as 'uh-rit' with emphasis on the second syllable. The 'en' in 'arytenoid' is pronounced 'uhn' and 'oid' is pronounced 'oyd'. Phonetic transcription is helpful in understanding the correct pronunciation of complex words such as 'arytenoid cartilage'.
Arytenoid cartilage is a small, paired structure located within the larynx, also known as the voice box, in humans. This cartilaginous structure plays a crucial role in vocal production and voice modulation.
The arytenoid cartilage is triangular in shape, resembling a pyramid, and is situated atop the cricoid cartilage, another cartilage within the larynx. Each arytenoid cartilage consists of a body, vocal process, muscular process, and apex. The vocal process extends anteriorly, connecting with the vocal folds (also known as vocal cords) and contributing to their movement during speech and singing. The muscular process, on the other hand, serves as an attachment site for muscles involved in vocal cord tension and relaxation.
The arytenoid cartilage plays a vital role in controlling the pitch, volume, and quality of sound produced by the vocal folds. It achieves this by participating in various movements that adjust the tension and position of the vocal folds. These movements include rocking, gliding, tilting, and rotation, which are facilitated by the intrinsic muscles of the larynx. The complex interplay between such muscles and the arytenoid cartilage allows for the intricate regulation of vocalization, influencing the tone and timbre of a person's voice.
In summary, the arytenoid cartilage is a key component of the larynx. It serves as a crucial structure involved in vocal production, facilitating the movement and adjustment of the vocal folds during speech and singing.

The word "arytenoid" is derived from the Greek words "arytenes" (meaning "pouched") and "eidos" (meaning "form" or "shape"). "Cartilage" originated from the Latin word "cartilago" (meaning "gristle" or "cartilage"). So, "arytenoid cartilage" essentially refers to the "pouched shaped cartilage" located in the larynx.
