Question

The inner lining of the Larynx is made up of _____________ epithelium.

Answer 1

Hint: The larynx is an organ located in the anterior part of the neck. It is a part of the respiratory tract. The laryngeal muscles move the parts of the larynx which is responsible for phonation and breathing. The larynx gets both motor and sensory innervation through the branches of the vagus nerve.

Complete solution:
The structure of the larynx is cartilaginous and it is held together by ligaments and membranes. The internal cavity can be divided into three parts:
Supraglottis – it extends from the inferior surface of epiglottis to the vestibular fold, also known as false vocal cords.
Glottis – it contains the vocal cords. The opening between the vocal cords is known as the rima glottidis. The size of this opening is altered by the muscles of phonation.
Sub glottis – it extends from the inferior border of the glottis to the inferior border of the cricoid cartilage.
The inner lining of the larynx is composed of stratified ciliated columnar epithelium.
Ciliated cells lining the respiratory tracts help in preventing mucus from clogging the tubes and also helps to clear other particles and microorganisms.

Note:
The larynx acts as a protective structure for the lower airways. It helps in respiration and plays an important role in phonation. In humans the protective and respiratory functions are replaced by the more important phonatory function. It also contains the vocal folds and ligaments that produce voice.
The arterial supply to the larynx is by the superior and inferior laryngeal arteries. Venous drainage happens via the superior and inferior laryngeal veins.
