The diaphragm is the main muscle of respiration and functions in breathing. During inhalation, the diaphragm contracts and moves in the inferior direction, enlarging the volume of the thoracic cavity and reducing intra-thoracic pressure (the external intercostal muscles also participate in this enlargement), forcing the lungs to expand.
Diaphragm (optics), a stop in the light path of a lens, having an aperture that regulates the amount of light that passes; Diaphragm (acoustics), a thin, semi-rigid membrane that vibrates to produce or transmit sound waves; Diaphragm (birth control), a small rubber dome placed in the vagina to wall off the cervix, thus preventing sperm from ...
In the case of the NeuRx device, a series of four incisions are made in the abdominal skin. Several tools such as a laparoscope and probe are used to find the best four locations on the diaphragm to attach four electrodes, which have connections outside the body. A fifth electrode is placed just under the skin in the same area.
In mechanics, a diaphragm is a sheet of a semi-flexible material anchored at its periphery and most often round in shape. It serves either as a barrier between two chambers, moving slightly up into one chamber or down into the other depending on differences in pressure , or as a device that vibrates when certain frequencies are applied to it.
The crus of diaphragm (pl.: crura), refers to one of two tendinous structures that extends below the diaphragm to the vertebral column. There is a right crus and a left crus, which together form a tether for muscular contraction. They take their name from their leg-shaped appearance – crus meaning leg in Latin.
A 46-year-old Swiss man who was paralyzed after falling on ice has regained some movement after a world-first surgery that installed an implant on his brain that uses artificial intelligence to ...
Implanted biomaterial can be loaded with different drugs to perform anti-inflammatory functions or promote angiogenesis to further integrate the implant with the host. [14] The sustained release of certain anti-inflammatory drugs from the biomaterial, such as dexamethasone , is shown to increase implant life by preventing inflammation and fibrosis.
Implants - •Intraocular lens: prosthetic lenses implanted after lens (anatomy) removal •Artificial eyes: as non-functional cosmetic implants into the eye socket Blade breaker: to break disposable blade after use to prevent reuse Thermo-cautery: to coagulate blood vessels and prevent haemorrhage: Cryoprobe: to freeze and extract the lens
