Stereocilia - Wikipedia
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. They contain actin.
Stereocilia (inner ear) - Wikipedia
Stereocilia of frog inner ear. In the inner ear, stereocilia are the mechanosensing organelles of hair cells, which respond to fluid motion in numerous types of animals for various functions, including hearing and balance.
Stereocilia: histology and function - Kenhub
Mar 27, 2024 · Stereocilia are cylindrical immotile microvilli found on the apical surfaces of epithelial cells. They are found in the epithelium of the epididymis, the proximal part of the ductus deferens and the sensory hair cells of the inner ear.
Anatomy, Head and Neck, Ear Organ of Corti
Jan 14, 2023 · The Organ of Corti is an inner ear organ located within the cochlea that contributes to audition. It includes 3 rows of outer hair cells and 1 row of inner hair cells. Vibrations caused by sound waves bend the stereocilia on these hair cells via an electromechanical force.
Stereocilia Rootlets: Actin-Based Structures That Are Essential for ...
Sensory hair cells of the inner ear rely on the hair bundle, a cluster of actin-filled stereocilia, to transduce auditory and vestibular stimuli into electrical impulses. Because they are long and thin projections, stereocilia are most prone to ...
The exquisite arrangement of stereocilia in the ear
Oct 19, 2022 · Sound waves enter the cochlea in the ear and prod stereocilia, tiny hair-like cellular protrusions aligned on the surface of sensory cells named ‘hair’ cells for this reason. Stereocilia movements create an electrical signal that the auditory nerve carries to the brain.
Building and repairing the stereocilia cytoskeleton in mammalian ...
Stereocilia are also interconnected by thin extracellular protein filaments (Fig. 1B, 1D), some of which (i.e. tip links) participate directly in mechano-electrical transduction, the major function of the hair bundle (Fig. 1E, 1F). In this review, we describe known molecules that play a role in the development and maintenance of the hair cell ...
Stereocilia - an overview | ScienceDirect Topics
Stereocilia are actin-based protrusions on auditory and vestibular sensory cells that are required for hearing and balance. They convert physical force from sound, head movement or gravity into an electrical signal, a process that is called mechanoelectrical transduction.
Stereocilia - an overview | ScienceDirect Topics
Stereocilia are finger-like projections from the apical surface of hair cells which are necessary for mechanosensory transduction of sound and for normal vestibular function. From: Trends in Molecular Medicine, 2003
Inner ear symptoms and disease: Pathophysiological …
The stereocilia of the inner ear hair cells are microvilli-derived and unique cell structures that correlate anatomically with distinct cochlear functions, including mechanoelectrical transduction, cochlear amplification, adaptation, frequency selectivity, and tuning.
