Resembling hair-like projections, the stereocilia are arranged in bundles of 30–300. [3] Within the bundles the stereocilia are often lined up in several rows of increasing height, similar to a staircase. At the core of these hair-like stereocilia are rigid cross-linked actin filaments, which can renew every
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.
Microvilli (sg.: microvillus) are microscopic cellular membrane protrusions that increase the surface area for diffusion and minimize any increase in volume, [1] and are involved in a wide variety of functions, including absorption, secretion, cellular adhesion, and mechanotransduction.
The hair bundle is composed of stiff microvilli called stereocilia and is involved with mechanoreception of sound waves. Stereocilia cells generate an electrical response to the vibrations of sound waves, crucial for normal hearing. This gene is part of a tandem duplication on chromosome 15; the second copy is a pseudogene.
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
Contrasting with stereocilia, which are numerous, there is only one kinocilium on each hair cell. 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 ...
