The vestibular sense is a sensory system that helps the body maintain balance and spatial orientation. It is primarily located in the inner ear, where structures called the semicircular canals and otolith organs detect changes in head position and movement. This information is crucial for coordinating movements and keeping the body upright. When the head moves, the fluid in the semicircular canals shifts, sending signals to the brain about the direction and speed of the movement. This allows individuals to perform activities like walking, running, or riding a bike without losing balance. The vestibular sense works closely with the visual system and proprioception to ensure smooth and coordinated actions.
