Question

Name the sound-producing organ of a human being ?

Answer 1

Hint: Organ present at the top of the neck between the pharynx and the trachea that is responsible for the change in pitch and the volume of the sound. It is prominent mostly in the case of males in humans as Adam's apple.

Complete answer:
The larynx is also called a voice box which is the sound- producing organ of human beings. It is involved in the process of respiration along with the production of sound, and also protects the trachea from choking while eating.

Additional Information:
- The larynx is a triangular- shaped organ that is made up of cartilages.
- It is attached to its surrounding tissues and organs through fibrous and elastic connective tissues.
- The larynx is also called vocal cords as they produce sound.
- It joins the inner part of the pharynx to the trachea which helps in breathing.
- It is made up of six cartilages which together constitute the laryngeal skeleton.
- The inner part of the larynx is divided into – supraglottis, glottis, and subglottis.
- Below the larynx is the pharynx which is divided into two parts; the trachea and the esophagus.
- The larynx has two types of muscles – intrinsic muscles (present between the larynx and it’s surrounding parts), and extrinsic muscles (present inside the larynx).
- The pitch and volume of the sound are maintained and manipulated by the larynx.
- The air is passed from the larynx to the lungs for respiration.

Note: The word larynx is derived from the ancient Greek word larynx meaning voice box. They consist of vocal folds that are responsible for the phonation which includes the pitch and the volume of the sound. The larynx is surrounded by the vagus nerve while the superior laryngeal nerve sends sensory information to the glottis and laryngeal vestibule.
