Vestibulo-ocular Reflex (VOR) | Structure & Physiology

The video tutorial explains the vestibulo-ocular reflex (VOR), focusing on its mechanism and physiological basis. It involves cranial nerves III, IV, and VI, with a primary focus on the oculomotor and abducent nerves. The tutorial includes a practical exercise to demonstrate how head movements result in compensatory eye movements to maintain gaze. The physiological basis involves the vestibular apparatus in the inner ear, which detects head rotation and signals the appropriate eye muscles to contract. The video also discusses clinical applications and encourages practice.
