Balance and the Ear Anatomy

The video tutorial explains the dual role of the ear in hearing and balance. It covers the anatomy of the inner ear, focusing on the semicircular canals and their function in detecting head movement. The role of the cerebellum in balance, the function of otoliths, and the integration of sensory systems, including proprioceptors and the visual system, are also discussed. The tutorial emphasizes the importance of understanding these components to grasp how balance is maintained.
