The chest drain stitch and corner stitch are variations of the horizontal mattress. [citation needed] Other stitches or suturing techniques include: Purse-string suture, a continuous, circular inverting suture which is made to secure apposition of the edges of a surgical or traumatic wound. [13] [14] Figure-of-eight stitch; Subcuticular stitch ...
The tip link is made of two different cadherin molecules, protocadherin 15 and cadherin 23. [4] It has been found that the tip links are relatively stiff, so it is thought that there has to be something else in the hair cells that is stretchy which allows the stereocilia to move back and forth.
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.
Catgut suture is a type of surgical suture made of twisted strands of purified collagen taken from the small intestine of domesticated ruminants or beef tendon. It is naturally degraded by the body's own proteolytic enzymes. Full tensile strength remains for at least 7 days, and absorption is complete by 90 days. This eventual disintegration ...
The inner root sheath or internal root sheath of the hair follicle is located between the outer root sheath and the hair shaft. [1] It is made of three layers: Henle's layer, Huxley's layer, and the cuticle. [2] The inner root sheaf serves to protect growing hair. [3]
Perilymph is found surrounding the sides and the bases of the hair cells. Perilymph is low in potassium and high in sodium . [ 8 ] [ 10 ] The different ionic makeups of the surrounding fluid in addition to the resting potential of the hair cell creates a potential difference across the apical membrane of the hair cell, so potassium enters when ...

One kinocilium is the longest cilium located on the hair cell next to 40–70 stereocilia. During movement of the body, the hair cell is depolarized when the stereocilia move toward the kinocilium. The depolarization of the hair cell causes neurotransmitter to be released and an increase in firing frequency of cranial nerve VIII. When the ...
