How does the vestibular system provide information to the brain?

Answer 1

The inner ear (hearing and balance) consists of a complex system of intercommunicating chambers and tubes called a labyrinth.

Information travels by way of the vestibulocochlear nerve (or auditory vestibular nerve), mostly known as the eighth cranial nerve.

Actually, two labyrinths compose the inner ear: the osseous labyrinth, bony canal in temporal bone and a membranous labyrinth, a membrane within osseous labyrinth.

The structures of the inner ear are:
o Cochlea = snail shaped portion;
 Function = sense of hearing.
o Semi-circular canals = three rings;
 Function = dynamic equilibrium.
o Vestibule = area between cochlea and semi-circular canals;
 Function = static equilibrium.

The brain receives information about balance, spatial orientation, and motion from the vestibular system, which is made up of a network of fluid-filled canals and sensory receptors in the inner ear. The fluid in the semicircular canals changes when the head moves, stimulating hair cells that transmit signals to the brain about the direction and speed of movement. The otolith organs also detect changes in head position in relation to gravity, transmitting information about linear acceleration and tilt, which is integrated in the brainstem and cerebellum to support balance and movement coordination.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
