Question

Which one of the following statements is NOT correct regarding trachea?
a) It usually lies posterior to muscular oesophagus.
b) It splits into right and left bronchi to supply air to the lungs.
c) Opening to the trachea is covered by epiglottis.
d) Trachea rings are incomplete cartilaginous and C shaped.

Answer 1

Answer:

option A

Explanation:

The normal position of the trachea is straight up and down, running along the center of the front side of the throat. Certain conditions can cause the trachea to shift to one side or the other.

Answer 2

The statement that is not correct regarding the trachea is, "It usually lies posterior to the muscular oesophagus."

• The trachea lies ventral or anterior to the oesophagus, not posterior.
• On entering the thoracic cavity, the trachea divides into two primary bronchi. The right bronchus is slightly larger.
• Epiglottis is the opening of the larynx that lies in the front. The trachea extends from the larynx in the neck to the bronchi in the thoracic cavity.
• The wall of the trachea is supported by C-shaped cartilaginous rings. These rings prevent collapsing of it.
