Question

Superior laryngeal nerve SLN location

Option 1:
a) External auditory canal

Option 2:
b) Nasal cavity

Option 3:
c) Oropharynx

Option 4:
d) Laryngopharynx

Answer 1

The Superior laryngeal nerve (SLN) is associated with the larynx, and its location is best related to the laryngopharynx, making option 4 (d) the correct answer.

Step-by-step explanation:

The Superior laryngeal nerve (SLN) location is related to the anatomy of the pharynx, which can be divided into three regions: the nasopharynx, the oropharynx, and the laryngopharynx. The SLN innervates the structures in the region of the larynx and splits into two branches: the internal branch and the external branch. The internal branch passes through the thyrohyoid membrane to provide sensation to the larynx above the vocal cords, while the external branch supplies motor function to the cricothyroid muscle.

Given the information provided, the laryngopharynx would be the correct answer, represented as option 4 (d), since it is adjacent to the larynx where the SLN is associated.
