The kinetic labyrinth functions via the semicircular
canals.
There are three semicircular
canals all at right angles to one another.
The function of the kinetic labyrinth is to detect if the body is in rotational motion.
Detection happens in the
ampulla, which spans the canal.
Inside
the ampulla lies the crista ampullaris.
It is made up of cupula and contains hair cells.
Furthermore, it is attached to sensory nerve
fibers.
Endolymph fills the canals and
is caused to move upon acceleration of the body.
This movement is detected by the
ampulla.
The information gathered is
sent to the vestibular nuclei, somatosensory cortex, spine, and cerebellum in
order to be processed and translated into information regarding balance,
position, posture, and movement.
