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 ...
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.
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.
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 ...
In the ELOM-080 study arm, effective alleviation of facial pain, the key symptom of ARS, was observed almost immediately. This trend continued over the entire treatment period. Clear improvements were likewise found with respect to further symptoms, such as headaches, stuffy nose, pain in the nasal sinuses upon percussion and pressure ...
In mammalian outer hair cells, the varying receptor potential is converted to active vibrations of the cell body. This mechanical response to electrical signals is termed somatic electromotility; [13] it drives variations in the cell's length, synchronized to the incoming sound signal, and provides mechanical amplification by feedback to the traveling wave.

Cilia occur in all members of the group (although the peculiar Suctoria only have them for part of their life cycle) and are variously used in swimming, crawling, attachment, feeding, and sensation. Ciliates are an important group of protists , common almost anywhere there is water—in lakes, ponds, oceans, rivers, and soils, including anoxic ...
