Question

Damage to the VII cranial nerve results in: A. Facial pain B. Absence of ability to smell C. Absence of eye movement D. Tinnitus

Short answer

Answer: The main consequence of damage to the VII cranial nerve is impaired facial expressions, taste, and some secretory functions.

Step-by-step solution

Understand the functions of the facial nerve

The VII cranial nerve, or facial nerve, controls several functions related to the face, such as facial expressions, taste, and some secretory functions. Therefore, when there is damage to this nerve, these functions may be affected.

Analyze the given options and identify the correct one

Now let's analyze each option and determine whether it is associated with the facial nerve's functions. A. Facial pain - This is not directly related to the functions of the facial nerve. B. Absence of ability to smell - This affects the I cranial nerve or olfactory nerve. C. Absence of eye movement - This affects III, IV, and VI cranial nerves. D. Tinnitus - This is not directly related to the functions of the facial nerve.

Choose the correct answer

As none of the given options directly describes the functions of the facial nerve, none of them are correct consequences of damage to the VII cranial nerve. However, it is important to note that in a scenario where such a question appears, there would typically be a correct answer available, and the above approach can be used to identify it.
