It is where the information is organized and integrated with the input of the cerebellum and cerebral cortex. The cerebellum which is the control center for movements send instruction to muscles to move and make adjustments to move body position which will maintain balance and coordination. The cerebral cortex, the thinking and memory center is responsible for priorly memorized information. Since integration of sensory have now occurred, the brainstem then sends impulses to the muscles which control the movements of eyes, head, trunk, and legs. ]]> 2020-09-06 06:33:31 UTC https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117626 manalocarlenerein https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117627 The stimulated tiny hairs transmit message through the balance nerve or the cranial nerve VIII (vestibulocochlear nerve) to the cerebellum. ]]> 2020-09-06 06:33:31 UTC https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117627 manalocarlenerein https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117628 For the control of eye movements, the oculomotor (CN III), trochlear (CN IV), and abducens (CN VI) are responsible for motor functions.]]> 2020-09-06 06:33:31 UTC https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117628 manalocarlenerein https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117630 For body movements, the accessory nerve and the vestibulospinal tracts are needed for the spinal motor control. ]]> 2020-09-06 06:33:31 UTC https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117630 BALANCE manalocarlenerein https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117631 2020-09-06 06:33:31 UTC https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117631 REFERENCES manalocarlenerein https://padlet.com/manalocarlenerein/usqw5x43w73ay20/wish/723117632 How does the balance system work?
