Sensitivity in Biological Definition

Insulin

... Type 1 diabetes). However, more commonly there is a decrease in the sensitivity of cells to insulin (eg, the reduced insulin sensitivity characteristic of Type 2 diabetes), resulting in decreased glucose ...

Albinism

... to refract within the eyeball. A good analogy would be taking a picture with a film camera that is painted white within, rather than black. Such sensitivity generally leads to a dislike of bright lights, but does not prevent people with albinism enjoying the outdoors. They should avoid prolonged exposure ...

Chromatography

... translates to narrower peaks in the resulting chromatogram and thence to better selectivity (it's easier to differentiate one peak from another) and sensitivity (tall, narrow peaks can be easier to discriminate from noise than shorter, broader peaks). Solvents used include any miscible combination of water ...

Diabetes mellitus

... most important forms of diabetes are due to decreased production of insulin (diabetes mellitus type 1, the first recognized form), or decreased sensitivity of body tissues to insulin (diabetes mellitus type 2, the more common form). The former requires insulin injections, while the latter is generally ...

Magnetic resonance imaging

... to patients during the operation. Such open bore magnets are often lower field magnets, typically in the 0.2 tesla range, which decreases their sensitivity but also decreases the Radio Frequency power potentially absorbed by the patient during a protracted operation. Radiation Therapy Simulation ...

Olfaction

... thousands. This is the reason why you can taste very little when you have a blocked nose. Olfaction in the animal kingdom The importance and sensitivity of smell varies among different organisms: most mammals have a good sense of smell, whereas most birds do not. As an exception among birds, ...

Signal transduction

... the hormone-producing cells can store prehormones , and quickly modify and release them if necessary. Also, the recipient cell can modify the sensitivity of the receptor, for example by phosphorylation ; also, the variation of the number of receptors can vary the total signal strength in the recipient ...

Optical spectrum

... from 400 to 700 nm , although some people may be able to perceive wavelengths from 380 to 780 nm . A light -adapted eye typically has its maximum sensitivity at ~555 nm , in the yellow region of the optical spectrum. Wavelengths visible to the eye are defined by the spectral range of the " optical ...
