Question

Which part of thyroid cartilage in the larynx is closed?
A. Dorsal
B. Ventral
C. Anterior
D. Posterior

Answer 1

Hint: The larynx is composed of 3 large, unpaired cartilages: cricoid, thyroid and epiglottis. The thyroid cartilage is the largest of the laryngeal cartilages. The thyroid cartilage forms a wall in front of the larynx to protect the vocal cords.

Complete answer:
 In this question, we have asked about the part of thyroid cartilage, which is closed in the larynx. As we already mentioned, the larynx is composed of three cartilages: cricoid, thyroid and epiglottis and thyroid is largest among them. The thyroid cartilage encircles the larynx but doesn't completely encircle the larynx. The thyrohyoid membrane is a ligament present with the thyroid cartilage that connects the thyroid cartilage with the hyoid bone. The thyroid cartilage is present in front of the larynx and above the thyroid gland or we can say larynx is present behind the thyroid cartilage. As we mentioned, the thyroid cartilage encircles the larynx and the circle is incomplete behind the larynx. So, we can say only the anterior part of thyroid cartilage is closed in the larynx. As thyroid cartilage is absent at the back of the larynx, it is also not present above and below the larynx.

So, the correct option is C. Anterior.

Note:
The two folds of thyroid cartilage meet in front which is small in females and large and prominent in males. It is made up of two lamina and these two lamina meet in the front of the neck which we call Adam's apple in male.
