An inner ear tumor has damaged a patient’s gelatinous otolithic membrane including its bounded calcium crystals called ear stones, AKA otoliths or otoconia. You expect them to have loss of which special sense?

The sodium-potassium ATPase electrogenic pump actively transports (3 or 2) sodium cations into the (ECF or ICF) then transports in (3 or 2) potassium cations into the (ECF or ICF). Hint – recall our membranes are polarized with a light negative charge buildup on the inner ICF side of the membrane and, in neurons and muscle cells, they must always return to this state via repolarization after they depolarize to fire an action potential, and they do so via this pump.

When ions move across the cell membrane, an electrochemical potential energy change results. Neurons take advantage of this to pickup sensory information and stimulate skeletal muscle movement, e.g., when you grab your pen to write, your brain uses sensory feedback from your fingers to modulate and refine movement of the skeletal muscles that control them. With that, which type of gated channel is operating most proximately (initially) in this pathway to allow sensory neuronal signaling to the brain?

The VOR (vestibulocochlear reflex) occurs when our eyes try to stabilize our focus during movement and do so via which three cranial nerves (remember the spinning we did in lab)? Hint: recall the cranial nerves that innervate the extraocular (extrinsic) eye muscles, not the cranial nerve involved in phototransduction.
