Final answer:
The vestibular sense contributes to balance and body posture, while proprioception and kinesthesia interact with it to control movement and reflexes. The practical significance of these senses lies in maintaining balance and compensating for changes in body position.
Step-by-step explanation:
The vestibular sense is responsible for maintaining balance and body posture, while proprioception and kinesthesia interact with the vestibular system to control movement and reflexes. The vestibular organs, located in the inner ear, are fluid-filled and have hair cells that respond to movement of the head and gravitational forces. When stimulated, these hair cells send signals to the brain via the vestibular nerve. The practical significance of these senses is evident in their role in maintaining balance, controlling movement, and compensating for changes in body position.
