Learning Objectives

  1. Review the anatomy of the peripheral and central vestibular system.
  2. Understand the basis of the vestibular ocular reflex.
  3. Understand how to identify the site of lesion in patients with vestibular disorders.
  4. Review the complex interactions of various systems and the pleotropic nature of the vestibular system.
  5. Understand the impact of aging on the vestibular system and clinical phenotype.

This is a self-scoring quiz. The correct answer will be revealed after you select your response. Your results will also be emailed to you.
