The kinocilium can be identified by its apical position as well as its enlarged tip. [1] Together with stereocilia, the kinocilium regulates depolarization and hyperpolarization of the hair cell, which is a neuron that can generate action potentials. When the stereocilia and kinocilium move further apart, the cell hyperpolarizes.
The macula of saccule lies in a nearly vertical position. It is a 2mm by 3mm patch of hair cells. Each hair cell of the macula contains 40 to 70 stereocilia and one true cilia, called a kinocilium. A gelatinous cover called the otolithic membrane envelops the tips of the stereocilia and kinocilium.
Hair cells in the vestibular system are slightly different from those in the auditory system, in that vestibular hair cells have one tallest cilium, termed the kinocilium. Bending the stereocilia toward the kinocilium depolarizes the cell and results in increased afferent activity .
Each hair cell of a macula has 40 to 70 stereocilia and one true cilium called a kinocilium. The stereocilia are oriented by the striola, a curved ridge that runs through the middle of the macula; in the saccule they are oriented away from the striola [2] The tips of the stereocilia and kinocilium are embedded in a gelatinous otolithic membrane ...
The stereocilia number from fifty to a hundred in each cell while being tightly packed together [2] and decrease in size the further away they are located from the kinocilium. [3] Mammalian cochlear hair cells are of two anatomically and functionally distinct types, known as outer, and inner hair cells.
The hair cells are made up of 40 to 70 stereocilia and one kinocilium, which is connected to an afferent nerve. Hair cells send signals down sensory nerve fibers which are interpreted by the brain as motion. In addition to sensing acceleration of the head, the otoliths can help to sense the orientation via gravity's effect on them.

The kinocilium is the only sensory aspect of the hair cell and is what causes hair cell polarization. The tips of these stereocilia and kinocilium are embedded in a gelatinous layer, which together with the statoconia form the otolithic membrane. [2] This membrane is weighted with calcium carbonate-protein granules called otoliths.
