The larynx is also called as
A. Voice Box
B. Soundbox
C. Black box
D. All of the above

Hint: The larynx is a small-sized organ present in the top of the neck. It is involved in breathing, talking, and swallowing. The larynx is sandwiched between the trachea and the pharynx. The air passes through the larynx blocking the food entrance and thus aiding in the respiratory system. In the male, the larynx enlarges and is called Adam’s apple.

Complete answer:
The larynx is an important organ of the respiratory system. The air passes through the larynx after entering the nasal cavity. It significantly protects the trachea from food aspiration. It lies just below the area where the pharynx splits into trachea and food pipe. It is a small triangular organ consisting of cartilages attached to one another. It is covered internally by a ciliated mucous membrane. The air from the pharynx enters into the larynx through an opening called the glottis. The glottis is further surrounded by flap-like structures called the epiglottis that guards it. Two folds of elastic tissue are present along the sides of the glottis. These tissues are called vocal cords. The vocal cords are responsible for sound production. As the larynx houses the vocal cords it is called a voice box.
In males, the larynx enlarges at the time of puberty and is termed as Adam’s apple. It can be seen as a pointed structure in front of the neck of males. The pitch and volume are manipulated by the larynx. In puberty, the male voice becomes hoarse-like and becomes deep. It is due to hormonal functions exerted over vocal cords.
Hence, the right answer is option B.

Note: Larynx is not only involved in voice production but also in protecting the lungs from the invasion of foreign substances. Coughing is one of the important reflexive actions performed by the larynx. Several things can cause larynx dysfunction. Some common symptoms that indicate larynx dysfunction are hoarseness, loss of voice, breathing difficulties, and pain in the throat or ears.
