What sense is responsible for detecting body movement, position, and balance?

The vestibular sense is responsible for detecting body movement, position, and balance. This sense is primarily facilitated by structures in the inner ear, specifically the semicircular canals and otolith organs. These structures contain fluid and hair-like sensors that respond to changes in head position and motion. When you move your head or change your body's orientation, the fluid in these canals shifts, allowing the sensory hair cells to send signals to the brain regarding your position and movement.

This information is critical for maintaining equilibrium and a sense of spatial orientation, enabling activities such as walking, running, or engaging in sports without losing balance. The vestibular system works in conjunction with visual and proprioceptive information to create a comprehensive understanding of our body's position relative to gravity and our environment.
