Answer 1

The larynx is the cartilaginous box which helps in the production of sound and is known as a soundbox. At the time of swallowing of food, the glottis can be covered by the thin elastic cartilaginous flap known as the epiglottis which prevents the entry of food in the larynx.

Complete answer:
The larynx is present at the top of the neck and it takes parts in breathing, production of voice, and protecting the trachea against food urge. The larynx includes the vocal folds and helps in the manipulation of pitch and the volume which is important in the process of phonation. The larynx is located just beneath the region of the pharynx which is divided into the trachea and the oesophagus.
The muscles in the larynx bring the vocal folds together which interrupts the escaping of air from the lungs. The many times they interrupt the flow of air per second it produces pitch. At the time adolescent the muscles of the larynx change and help in the production of hoarse voices in males. So, it changes the voice of the males.
This, the proper answer is: the overgrowth of muscles into the larynx leads to the hoarse voice in adolescent boys.

Note: The muscles of the larynx put the vocal folds into the position for the vibration. The muscles that elevate the larynx are the suprahyoid muscles and the stylopharyngeus while the muscles infrahyoid depress the muscles.
