How many systems work together to maintain a person's sense of balance?

The correct answer indicates that three systems work together to maintain a person's sense of balance. These systems include the vestibular system, the visual system, and the somatosensory system.

The vestibular system, located in the inner ear, detects changes in head position and motion, providing information about balance and spatial orientation. The visual system contributes by allowing individuals to perceive their surroundings and assess their position relative to objects around them. The somatosensory system encompasses receptors in the skin, muscles, and joints, helping to detect changes in body position and movement.

Together, these three systems integrate their respective information to create a comprehensive understanding of balance, enabling the body to maintain stability during movement and when at rest. Understanding the interaction of these systems is crucial for developing effective corrective exercise strategies, particularly for individuals with balance impairments.
