Found Microscope 30 times.

Displaying results 1 to 10.

1. Artifact
The appearance of a structure under a microscope which is not actually present but is the result of procedures used to prepare the slide. An apparent experimental result that is not actually real but is due to the experimental methods.

2. Balbiani rings (chromosome puffs)
Giant puffs on a polytene chromosome in the salivary glands of certain insect larvae which, when present, means that transcription of DNA is taking place. The puffs are areas where the chromosome has become decondensed for the purpose, and are easily visible with a light microscope.

3. Biomicroscopy
The examination of tissues on a microscopic level. Could refer to the specific examination of the cornea or lens of the eye, using a corneal microscope and a slit lamp.

4. Biopsy
* To remove a sample of tissue from the body in order to examine it with a microscope for signs of disease, usually to help make a diagnosis. * The sample of tissue removed in order for it to be examined under a microscope for signs of disease so that an accurate diagnosis can be made.

5. Colposcopy
This is a direct examination of the vagina and the cervix with an instrument fitted with a binocular low power microscope (from 13.5 to 60 x). Candidates for this procedure include those with abnormal Pap smear test and those exposed to diethystilbestrol in utero. Biopsy may be taken under the guidance of colposcopy.

6. Contrast
In relation to microscopes, the ability to distinguish different densities of structures.

7. Coronavirus
A genus of pleomorph ic virus es which look like coronas or halos when viewed with a microscope. It is the single genus of the family Coronaviridae. Members of Coronavirus cause hepatitis (inflammation of the liver) in mice, gastroenteritis (inflammation of the digestive system) in pigs, and respiratory infections in birds and people.

8. Cryofixation
A process of preparing cell s to be examined under an electron microscope by freezing them.

9. Dark field microscopy (dark field microscope, dark field imaging, dark-field illumination, dark-ground illumination)
The use of a microscope which is lit by a beam of light or electron s that has been refracted, diffracted, or condensed and diffused, so that only certain parts of the object being studied are lit while the rest of the field of view is dark, to study tiny particles or lines.

10. Electron microscope
A microscope (device used to magnify small objects) which beams electron s at and through the object of interest instead of light beams. Instead of a glass lens to bend the light, a powerful magnet is used to bend the electron beam. The microscope can only be operated in a vacuum. This type of microscope provides the greatest resolution of extremely small details available and has been used to see individual atoms in an object or substance.
