Question

Which organ is called a voice box?

Answer 1

Hint: Voicebox is a tube-shaped organ present in the neck. It is a portion of the respiratory tract which comprises the vocal cord that produces sound. It is found between the pharynx and the trachea.

Complete answer:
> The larynx is known as a voice box or a sound-producing organ. A pair of membranous folds called vocal cords, expanse across the laryngeal cavity. In normal situations, the vocal cords lie apart so that the glottis stays widely open to allow free passage of respiratory air. For sound production, vocal cords come close together, they vibrate when air rushes out through glottis and creative voice.
Structure: The larynx is an external skeleton of cartilage plates that avoid the collapse of the structure. The plates are attached by membranes and muscle fibres. The front set of plates is called thyroid cartilage, has a central ridge and elevation commonly known as Adam’s apple.
> The epiglottis, at the upper part of the larynx, is a flap like outgrowth into the throat. As the food is swallowed, the whole larynx structure increases to the epiglottis so that the passage to the respiratory tract is blocked.
> The centre portion of the larynx is reduced to slit-like spaces in two sites. Both sites denote large folds in the mucous membrane lining the larynx. The first pair is known as the false vocal cords, whereas the second is the true vocal cords (glottis).

Note: The larynx or plural larynges, collectively known as the voice box, an organ in the neck of land vertebrates involved in the protection of the trachea and some of them are sound production and vibration of the larynx.
