Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Walls of the trachea are supported by ____
A
cricoid cartilages
B
tracheal cartilages
C
thyroid cartilages
D
None of the above
Explanation: 

Detailed explanation-1: -Rings of cartilage are present in the trachea to prevent its collapse when the air is not passing through it. The cartilage is a flexible connective tissue, and it supports the trachea while still allowing it to move and flex during breathing.

Detailed explanation-2: -A normal trachea (windpipe) has many rings made of cartilage (a strong and flexible tissue). These rings are C-shaped and support the trachea but also allow it to move and flex when your child breathes. Complete tracheal rings are a birth defect in these rings that causes them to be O-shaped instead of C-shaped.

Detailed explanation-3: -The hyaline cartilage in the tracheal wall provides support and keeps the trachea from collapsing.

Detailed explanation-4: -The cartilaginous ring is strong and flexible. It supports the trachea and prevents it from collapsing. The presence of tracheal C-shaped cartilaginous rings helps in the flexible movement of the neck during breathing. Due to this reason, the trachea is supported by cartilaginous rings.

Detailed explanation-5: -It consists of 16-20 tracheal cartilages anterolaterally and a fibromuscular wall posteriorly. The tracheal cartilages are composed of hyaline cartilage and interconnected by fibroelastic tissue.
