The term "vestibular" refers to the system in the body that helps maintain balance and spatial orientation. This system is primarily located in the inner ear and includes structures such as the semicircular canals and otolith organs. These components detect changes in head position and movement, sending signals to the brain to help coordinate balance and posture. The vestibular system works closely with other sensory systems, including vision and proprioception, to provide a comprehensive understanding of body position in space. When this system is functioning properly, it allows individuals to move smoothly and maintain stability, whether standing still or in motion.
