Sound above a certain decibel level can cause permanent damage to inner ear stereocilia. New research has shown that the damage can possibly be reversed if we can repair or recreate some of the proteins in the stereocilia. In this study, scientists used zebrafish to examine the motion of proteins within live ear cells using a confocal ...
Primary ciliary dyskinesia (PCD) is a rare, autosomal recessive genetic ciliopathy, that causes defects in the action of cilia lining the upper and lower respiratory tract, sinuses, Eustachian tube, middle ear, fallopian tube, and flagella of sperm cells. The alternative name of "immotile ciliary syndrome" is no longer favored as the cilia do ...
Some motile cilia lack the central pair, and some non-motile cilia have the central pair, hence the four types. [5] [7] Most non-motile cilia, termed primary cilia or sensory cilia, serve solely as sensory organelles. [8] [9] Most vertebrate cell types possess a single non-motile primary cilium, which functions as a cellular antenna.
Nasal hair or nose hair is the hair in the nostril. Adult human noses have hairs, which serve as a crude air filter to stop foreign particles from entering the nasal cavity, as well as to help collect moisture. [1] Nasal hair is different from the cilia of the ciliated lining of the nasal cavity.
Aural/Ear syringe: used to flush out anything like ear wax or foreign bodies from the external ear Toynbee's auscultation tube: Otoscope/Auriscope: to examine the external auditory canal and ear drum; used during aural toileting, removal of wax, myringotomy, stapedectomy and to dilate the stenosis of canal Mouth gag - •Doyen's mouth gag
A ciliopathy is any genetic disorder that affects the cellular cilia or the cilia anchoring structures, the basal bodies, [1] or ciliary function. [2] Primary cilia are important in guiding the process of development, so abnormal ciliary function while an embryo is developing can lead to a set of malformations that can occur regardless of the particular genetic problem.

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 are found in the vas deferens, the epididymis, and the sensory cells of the inner ear.
