Summary Introduction

To review:

Match the term extrinsic laryngeal musculature with the most closely related description given below:

Superior portion of the pharynx

Bridge of the nose

Nose, nasal cavity, paranasal sinuses, nasal conchae, and nasopharynx

Windpipe

Lobar bronchi

Contains and protects the glottis

Larynx, trachea, bronchi, bronchioles, and alveoli of the lungs

Provide protection for the vocal folds

Positions and stabilizes the larynx

Segmental bronchi

Introduction:

The larynx is also known as voice box and consists of laryngeal muscles. These muscles are segregated on the basis of muscles’s location. These muscles are further classified as extrinsic and the intrinsic muscles.

Explanation of Solution

The extrinsic musculature consists of one muscle that embeds into the laryngeal cartilage and the other in its adjacent structures. The main function of the extrinsic muscles includes providing stability and support to the larynx. It connects larynx to other structures and muscles for up and down movement during food swallowing and avoids food to enter glottis while speaking. Some of the extrinsic muscles are inferior constrictor muscles, sternothyroid muscles, mylohyoid muscles, digastric, omohyoid muscles, and thyrohyoid muscles.

Conclusion

Therefore, it can be concluded that extrinsic laryngeal musculature can be correctly matched with the option (i) positions and stabilizes the larynx.
