Cervical VEMP (cVEMP) tests the integrity of which vestibular structure?

• A Utricle and superior vestibular nerve
• B Horizontal semicircular canal
• C Superior semicircular canal
• D Saccule and inferior vestibular nerve ✓

Explanation

cVEMP is an inhibitory myogenic potential recorded from the ipsilateral sternocleidomastoid muscle in response to loud sound stimuli; it reflects the vestibulo-collic reflex pathway: saccule → inferior vestibular nerve → lateral vestibular nucleus → accessory nucleus → SCM. Ocular VEMP (oVEMP) tests the utricle via the superior vestibular nerve. The semicircular canals are tested by caloric and rotation chair tests.
