All are true about stapedial reflex except
**Core Concept**
The stapedial reflex is a reflexive contraction of the stapedius muscle in response to loud sounds, protecting the inner ear from damage. This reflex is mediated by the vestibulocochlear nerve (cranial nerve VIII) and the facial nerve (cranial nerve VII).
**Why the Correct Answer is Right**
The stapedial reflex helps to reduce the intensity of sound waves by contracting the stapedius muscle, which reduces the movement of the stapes bone in the middle ear. This reflex is an important mechanism for protecting the delicate structures of the inner ear from damage caused by excessive sound levels. The reflex is also responsible for the sensation of discomfort or pain in the ear when exposed to loud noises.

**Clinical Pearl / High-Yield Fact**
The stapedial reflex can be used as a clinical test to assess the integrity of the vestibulocochlear nerve and the facial nerve. A decreased or absent stapedial reflex may indicate a problem with one of these nerves.
