Question

Which anatomical structure is responsible for the horizontal Nystagmus produced during stimulation of the VOR reflex?

a) Cochlea
b) Semicircular canals
c) Utricle
d) Saccule

Answer 1

The semicircular canals in the inner ear are responsible for the horizontal nystagmus during stimulation of the VOR reflex.

Step-by-step explanation:

The horizontal nystagmus produced during stimulation of the VOR reflex is primarily caused by the semicircular canals in the inner ear.

The semicircular canals are part of the vestibular system, which is responsible for sensing balance and spatial orientation.

When the head moves, the fluid in the semicircular canals shifts, resulting in the bending of the cristae ampullaris and the stimulation of the vestibular nerve.
