Question

Cartilaginous rings in trachea are incomplete at which surface?

• A. Dorsal
• B. Ventral
• C. Lateral
• D. Ventrolateral

Answer 1

The correct option is A Dorsal

The trachea (windpipe) is a tube that extends from the lower edge of the larynx to the upper part of the chest (above the heart). It has a framework of cartilages to keep it open. These cartilages are shaped like a tiny horseshoe or the letter C and are found along the entire length of the trachea. All the open sections of these cartilages are at the dorsal surface so that the oesophagus can bulge into the open section during swallowing. The purpose of the trachea is to conduct air between the larynx and the lungs.

So, the correct answer is option A.
