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.

Examples

1. The other organs, the utricle and saccule, works similarly.

2. Right next to the cochlea is the tiny vestibular system, which includes three semicircular canals, and tiny segments called the utricle and saccule, all of which are filled with fluid.

3. And it's during the final stage of lung development, called alveolarization, where larger lungs saccules divide into tiny air sacs and dramatically increase the gas exchange surface area of the lung.

4. In your inner ear, there are these tiny hairs called stereocilia, that line a pouchlike structure called the saccule.
