chronoscopy (s) (noun)
, chronoscopies (p)
The process of measuring very short periods of time by using a chronoscope: With the method of chronoscopy, observations and exact measurements of short-lived occurrences can be determined.
An instrument for examining the ciliary (eyelids or eyelashes) region of the eye.
cinemascope, Cinema Scope
A motion-picture process employing a special type of lens to project a panoramic, three-dimensional image upon a wide, curved screen; a trade name.
A reference to the projection of images that are almost two and a half times as wide as they are high.
A long flexible endoscope, often equipped with a device for obtaining tissue samples, which is used for the visual examination of the colon.
The medical examination of the colon by a physician who uses a colonoscope.
1. A special microscope for the direct visual examination of the cervical or neck tissue.
2. An instrument which is inserted into the vagina for examination of the vagina and the cervix (entrance to the womb) by means of a magnifying lens.
It is used primarily to identify abnormal vascular and epithelial patterns associated with early neoplasia or formation of tumors.
Direct observation and study of cells within the vagina and the cervix magnified in vivo (in the living body) by means of a special microscope.
A surgical instrument used to examine the vagina and the cervix of the womb.
The examination of the cervix (entrance to the womb) and the vagina with a colposcope.
1. A speculum for examining the walls of the nasal cavity.
2. A tubular speculum incorporating a mirror, once used for median rhinoscopy.
3. An instrument for examining the interior of the nose.
cosmic-ray telescope (s) (noun)
, cosmic-ray telescopes (pl)
An instrument used to detect and identify the direction of cosmic rays or the material that results when cosmic rays interact with the atmosphere.
A microscopic journey through tiny universes or worlds.
A reference to, or description of, microscopic voyages through tiny universes or worlds.
cryoelectron microscopy, cryo-electron microscopy (s) (noun)
; cryoelectron microscopies, cryo-electron microscopies (pl)
An electron microscopic technique that involves freezing the biological sample in order to view the sample with the least possible distortion and the fewest possible artifacts. Abbreviated as cryo-EM
In cryoelectron microscopy, the freezing of the sample is done in ethane slush to produce vitreous, or non-crystalline, ice. The frozen sample grid is then kept at liquid nitrogen temperature in the electron microscope and digital micrographs are collected with a camera.
The advantages of cryo-EM over traditional EM techniques include the preservation of the sample in a near-native hydrated state without the distortions from stains or fixatives needed for traditional EM. With image processing and averaging of multiple images, cyroelectron microscopy provides high resolution information (below 10 angstroms).
An angstrom is a metric unit of length equal to one ten billionth of a meter (or 0.0001 micron); used to specify wavelengths of electromagnetic radiation.
