The incorrect option about the larynx (sound box) is option 'A' - "It is a bony box".
Explanation:
The larynx, commonly known as the voice box, is a part of the respiratory system situated in the neck. It is involved in the production of sound, protection of airways, and swallowing. Let's discuss each option to understand why option 'A' is incorrect.
a) It is a bony box:
This statement is incorrect. The larynx is not a bony structure; instead, it is made up of cartilages. The primary cartilages of the larynx include the thyroid cartilage (Adam's apple), cricoid cartilage, and epiglottis. These cartilages provide support, shape, and protection to the larynx.
b) Glottis is the opening into the larynx:
This statement is correct. The glottis refers to the opening between the vocal cords in the larynx. It is through the glottis that air passes during breathing and sound is produced when the vocal cords vibrate.
c) During swallowing of food, the glottis is covered by the epiglottis to prevent food entry into the larynx:
This statement is correct. The epiglottis is a leaf-shaped elastic cartilage located above the glottis. During swallowing, the epiglottis moves downward to cover the glottis, preventing food or liquids from entering the larynx and trachea. This helps to direct the swallowed material into the esophagus and prevents it from entering the respiratory tract.
d) All of these:
This option is incorrect because option 'A' is incorrect. As discussed earlier, the larynx is not a bony box; it is a structure made up of cartilages.
Conclusion:
In conclusion, the incorrect option about the larynx is option 'A' - "It is a bony box". The larynx is not a bony structure; instead, it is composed of cartilages that support and protect the vocal cords and assist in the production of sound.
