What is the primary function of the vestibular system?

The primary function of the vestibular system is to maintain balance and spatial orientation. This system is located in the inner ear and consists of structures that detect changes in head position and motion. It plays a crucial role in integrating sensory information from the visual and proprioceptive systems to help coordinate body movements and stabilize vision during motion.

When the head moves, the vestibular system sends signals to the brain that inform it about the direction and speed of the movement. This information is vital for maintaining equilibrium, enabling individuals to stand upright, walk, and navigate through their environment without losing balance. The vestibular system is essential for activities that require coordination and spatial awareness, such as riding a bicycle or participating in sports.
