| A/C | albumin/coagulin [ratio]; anterior chamber of eye; assist control [ventilation] |
| posterior chamber of eye | The ringlike space, filled with aqueous humor, between the iris/pupil anteriorly and the lens and ciliary body posteriorly. Synonym: camera posterior bulbi, camera oculi minor, camera oculi posterior. (05 Mar 2000) |

| Haldane chamber | An obsolete chamber for metabolic studies on animals. (05 Mar 2000) |
| Sandison-Clark chamber | A chamber that can be fitted over a hole punched in a rabbit's ear, so that tissue will grow to fill the defect between two transparent plates; if the distance between the plates is small, the living tissue can be studied microscopically. (05 Mar 2000) |
| high altitude chamber | A decompression chamber for simulating a high altitude environment, particularly its low barometric pressure. Synonym: high altitude chamber. (05 Mar 2000) |
| hyperbaric chamber | <apparatus> A pressurised chamber that allows for the delivery of oxygen in higher concentrations for therapeutic benefit. Useful in the treatment of severe burns, peripheral vascular disease, carbon monoxide poisoning and decompression illness. (27 Sep 1997) |
| sinoatrial chamber | <anatomy> The common chamber formed by the single embryonic atrium and the right and left horns of the sinus venosus. (20 Jun 2000) |
| sinuatrial chamber | <anatomy> The common chamber formed by the single embryonic atrium and the right and left horns of the sinus venosus. (20 Jun 2000) |
| specimen chamber | <microscopy> The compartment located in the column of the electron microscope in which the specimen is placed for observation. (05 Aug 1998) |
| decompression chamber | <apparatus> A steel chamber that is used to apply oxygen under pressure to reverse the effects of the bends or to treat other forms of barotrauma. Synonym: hyperbaric chamber. (27 Sep 1997) |
| ionization chamber | A chamber for detecting ionization of the enclosed gas; used for determining intensity of ionizing radiation. (05 Mar 2000) |
| orientation chamber | <cell culture> Chamber designed by Zigmond in which to test the ability of cells (neutrophils) to orient in a gradient of chemoattractant. The chamber is similar to a haemocytometer, but with a depth of only ca. 20m. The gradient is set up by diffusion from one well to the other and the orientation of cells towards the well containing chemoattractant is scored on the basis of their morphology or by filming their movement. (18 Nov 1997) |
| endothelium of anterior chamber | A single layer of large, squamous cells that covers the posterior surface of the cornea. Synonym: endothelium camerae anterioris. (05 Mar 2000) |
| Zappert counting chamber | A special, standardised glass slide used for counting cells (especially erythrocytes and leukocytes) and other particulate material in a measured volume of fluid; the central portion is precisely ground in such a manner that the uniformly flat surface is exactly 0.1 mm lower than that of two parallel ridges on which a special, uniformly flat coverslip may be placed; accurately etched lines on the flat central portion form the boundaries of groups of squares of known areas, thereby providing the basis for determining the volume of fluid in which the cells are counted. Glass slides of this type are frequently known as haemocytometers. (05 Mar 2000) |
| Zigmond chamber | <cell culture> Chamber designed by Zigmond in which to test the ability of cells (neutrophils) to orient in a gradient of chemoattractant. The chamber is similar to a haemocytometer, but with a depth of only ca. 20m. The gradient is set up by diffusion from one well to the other and the orientation of cells towards the well containing chemoattractant is scored on the basis of their morphology or by filming their movement.

| Ammon's horn | One of the two interlocking gyri composing the hippocampus, the other being the dentate gyrus. Synonym: cornu ammonis. Origin: G. Ammon, the Egyptian deity Amun (05 Mar 2000) |
