Question

Match what runs with what:

A. superior laryngeal nn
B. internal laryngeal nn
C. recurrent laryngeal nn

superior laryngeal artery
inferior thyroid artery
superior thyroid artery
a. A-1, B-2, C-3
b. A-3, B-2, C-1
c. A-2, B-1, C-3
d. A-2, B-3, C-1

Answer 1

The correct matching for the nerves with their corresponding arteries is A-1, B-2, C-3; where the superior laryngeal nerve and internal laryngeal nerve run with the superior thyroid artery, and the recurrent laryngeal nerve runs with the inferior thyroid artery.

Step-by-step explanation:

The student's question involves matching nerves to the corresponding arteries that run with them. For a correct match, we need to associate the following :

• Superior laryngeal nerve (A) with the superior thyroid artery,
• Internal laryngeal nerve (B), which is a branch of the superior laryngeal nerve, runs with branches of the superior thyroid artery,
• Recurrent laryngeal nerve (C), which is known to run with the inferior thyroid artery.

Hence, the correct match is:

1. A - superior thyroid artery,
2. B - superior thyroid artery (as it is a continuation), and
3. C - inferior thyroid artery.

The options provided can be confusing because two nerves (A and B) run with the same artery. However, if you know the anatomy well, you can deduce that since B is a branch of A and they follow the same path initially, they run with the same artery. Thus, the correct answer here would be option A (A-1, B-2, C-3).
