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.
Older children's bones do not conform as easily to the bar, thus increasing the risk of bar displacement, so the wire attaching the bar directly to the sternum may help avoid a second surgery to correct bar displacement. Eventually, the bar is secured with muscle tissue that regrows during the recovery time.
One major advantage of the resin-retained bridge over a conventional bridge is the failure mode is likely to be debonding of the retainer. In conventional bridges, the failure mode is likely to be complete fracture of the abutment tooth with difficult-to-manage sequelae, possibly requiring root canal treatment. With a resin-retained bridge the ...
Surgical mesh is a medical implant made of loosely woven mesh, which is used in surgery as either a permanent or temporary structural support for organs and other tissues. Surgical mesh can be made from both inorganic and biological materials and is used in a variety of surgeries, although hernia repair is the most common application.
An artificial organ is a human-made organ device or tissue that is implanted or integrated into a human – interfacing with living tissue – to replace a natural organ, to duplicate or augment a specific function or functions so the patient may return to a normal life as soon as possible. [1]
Diaphragm pacing (and even earlier as electrophrenic respiration [1] [2]) is the rhythmic application of electrical impulses to the diaphragm to provide artificial ventilatory support for respiratory failure or sleep apnea.
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
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 ...
