chamber
[chām´ber]an enclosed space.
Chambers of the eye. From Dorland's, 2000.
anterior chamber the part of the aqueous humor-containing space of the eyeball between the cornea and iris.
counting chamber the part of a hemacytometer consisting of a microscopic slide with a depression whose base is marked in grids, and into which a measured volume of a sample of blood or bacterial culture is placed and covered with a cover glass. The number of cells and formed blood elements in the squares is counted under a microscope and used as a representative sample for calculating the unit volume.
drip chamber the expanded portion of intravenous tubing into which fluid falls, where the rate of flow can be monitored if necessary. See also intravenous infusion.
hyperbaric chamber an enclosed space in which gas (oxygen) can be raised to greater than atmospheric pressure; see also hyperbaric oxygenation.
ionization chamber an enclosure containing two or more electrodes between which an electric current may be passed when the enclosed gas is ionized by radiation; used for determining the intensity of x-rays and other rays.
posterior chamber that part of the aqueous humor–containing space of the eyeball between the iris and the lens.
vitreous chamber the vitreous humor–containing space in the eyeball, bounded anteriorly by the lens and ciliary body and posteriorly by the posterior wall of the eyeball.

In anatomy, a small cavity.
anterior chamber (AC) Space within the eye filled with aqueous humour and bounded anteriorly by the cornea and posteriorly by the iris and the part of the anterior surface of the lens which appears through the pupil. Its average axial length is 3.2 mm. See angle of the anterior chamber; aqueous flare; gonioscope; Shaffer and Schwartz van Herick method; Smith's method; optics of the eye; shadow test.
chamber's of the eye The anterior, posterior and vitreous chambers of the eye.
posterior chamber Space within the eye filled with aqueous humour and bounded by the posterior surface of the iris, the ciliary processes, the zonule and the anterior surface of the lens.
vitreous chamber Space within the eye filled with vitreous humour and bounded by the retina, ciliary body, canal of Petit and the postlenticular space of Berger.
