The Role of the Vestibular System in Balance and Spatial Awareness

The video explores the human senses, focusing on the vestibular system's role in balance and spatial orientation. It details the inner ear's structure, including the cochlea and semicircular canals, explaining how they detect sound and head movement. The idolithic organs, containing crystals, help sense linear acceleration and head positioning. The video also discusses dizziness, its causes, and how it can be managed, especially in environments lacking gravity or visual cues.
