The otolith organs are small structures located in the inner ear, specifically within the vestibular system. They play a crucial role in maintaining balance and spatial orientation by detecting changes in head position and motion. The organs contain tiny calcium carbonate crystals, called otoconia, that shift in response to gravity and movement, sending signals to the brain about the body's position. There are two main types of otolith organs: the utricle and the saccule. The utricle detects horizontal movements, while the saccule responds to vertical movements. Together, they help the body understand its orientation in space, contributing to overall balance and coordination.
