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

Solution

Ques-1:

When eyes are open, sensory information goes to through the retina to bipolar neurons followed by glutamate activity, however, the equilibrium is maintained by the ampullae of the semicircular canals (sensory organs) of inner ear

Ques-2: When eyes are closed, the vesibulocochlear apparatus (sensory organs) functions to maintain static body equilibrium & this apparatus is present in the inner ear

Mechanism:

Static equilibrium & vestibular apparatus:

Vestibular apparatus are containing special sensory apparatus to maintain static equilibrium. They are utricle, saccule with a muclae that have potential mechanoreceptors to process “head and body posture stability with central nervous system”. The process of equilibrium is through vestibular verve finally to the brain for interpretation of sensory information.
