Hearing & Balance: Crash Course Anatomy & Physiology #17

Crash Course Anatomy & Physiology continues the journey through sensory systems with a look at how your sense of hearing works. We follow sounds as they work their way into the ear where they are registered and transformed into action potentials. This mechanism not only helps you hear but also helps maintain your equilibrium.
