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.
Bending the stereocilia away from the kinocilium hyperpolarizes the cell and results in a decrease in afferent activity. In the semicircular canals, the hair cells are found in the crista ampullaris , and the stereocilia protrude into the ampullary cupula .
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.
Each hair cell of a macula has forty to seventy stereocilia and one true cilium called a kinocilium. The tips of these cilia are embedded in an otolithic membrane. This membrane is weighted down with protein-calcium carbonate granules called otoconia.
Every hair cell in these sensory beds consist of 40-70 stereocilia and a kinocilium. [2] The stereocilia and kinocilium are embedded in the otolithic membrane and are essential in the function of the otolith organs. The hair cells are deflected by structures called otoconia.
These microscopic structures possess stereocilia and one kinocilium which are located within the gelatinous otolithic membrane. The membrane is further weighted with otoliths. Movement of the stereocilia and kinocilium enable the hair cells of the saccula and utricle to detect motion.
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. This membrane is weighted with protein-calcium carbonate granules called otoliths, which ...
Stereocilia (or stereovilli or villi) are non-motile apical cell modifications. They are distinct from cilia and microvilli , but are closely related to microvilli. They form single "finger-like" projections that may be branched, with normal cell membrane characteristics.
