"saccule" の定義と意味

What is "saccule"?

The saccule is a sensory organ located within the inner ear, specifically within the vestibular system. It plays a crucial role in our sense of balance and spatial orientation. The saccule contains specialized cells that are sensitive to changes in linear acceleration and head position, allowing us to maintain stability and perceive our body's position in relation to gravity. This information is relayed to the brain, contributing to our overall sense of equilibrium and helping us maintain proper posture and coordination.
