When the eyes are closed what sensory organs provide information needed to maintain equilibrium?

When the eyes are closed, the vestibular system in the inner ear plays a crucial role in providing information needed to maintain equilibrium. This system includes the semicircular canals and otolith organs, which detect changes in head position and movement. The brain integrates this information with input from proprioceptors in the muscles and joints to help us stay balanced even without visual cues.
