| intracellular | <anatomy> Being or occurring within a body cell or within the body cells. (09 Oct 1997) |
|---|---|
| intracellular canaliculus | <cell biology> A fine canal formed by invagination of the cell membrane into the cytoplasm of a cell, such as those of the parietal cells of the stomach. (05 Mar 2000) |
| intracellular digestion | <cell biology> Digestion within the boundaries of a cell, such as occurs in the protozoa and in phagocytes. (05 Mar 2000) |
| intracellular enzyme | <enzyme> An enzyme that performs its functions within the cell that produces it; most enzyme's are intracellular enzyme's. Synonym: endoenzyme. (05 Mar 2000) |
| intracellular fluid | The fluid within the tissue cells, constituting about 30 to 40% of the body weight. (05 Mar 2000) |
| intracellular membranes | Membranes of subcellular structures. (12 Dec 1998) |
| intracellular toxin | <protein> Heat stable polysaccharide like toxin bound to a bacterial cell. The term is used more specifically to refer to lipopolysaccharide (LPS) of the outer membrane of gram-negative bacteria. There are three parts to the molecule, the Lipid A (six fatty acid chains linked to two glucosamine residues), the core oligosaccharide (branched chain of ten sugars) and a variable length polysaccharide side chain (up to 40 sugar units in smooth forms) that can be removed without affecting the toxicity (rough LPS). Some endotoxin is probably released into the medium and endotoxin is responsible for many of the virulent effects of gram-negative bacteria. (18 Nov 1997) |
| active electrode | A small electrode whose exciting effect is used to stimulate or record potentials from a localised area. Synonym: exciting electrode, localizing electrode, therapeutic electrode. (05 Mar 2000) |
| calomel electrode | An electrode in which the wire is connected through a pool of mercury to a paste of mercurous chloride (Hg2Cl2, calomel) in a potassium chloride solution covered by more potassium chloride solution; commonly used as a reference electrode. (05 Mar 2000) |
| carbon dioxide electrode | A glass electrode in a film of bicarbonate solution covered by a thin plastic membrane permeable to carbon dioxide but impermeable to water and electrolytes; the carbon dioxide pressure of a gas or liquid sample quickly equilibrates through the membrane and is measured in terms of the resulting pH of the bicarbonate solution, as sensed by the glass electrode; commonly used to analyze arterial blood samples. Synonym: Severinghaus electrode. (05 Mar 2000) |
| redox electrode | An electrode capable of measuring oxidation-reduction potential. See: quinhydrone electrode. Synonym: redox electrode. (05 Mar 2000) |
| reference electrode | An electrode expected to have a constant potential, such as a calomel electrode, and used with another electrode to complete an electrical circuit through a solution; e.g., when a reference electrode is used with a glass electrode for pH measurement, changes in voltage between the two electrode's can be attributed to the effects of pH on the glass electrode alone. (05 Mar 2000) |
| glass electrode | A thin-walled glass bulb containing a standard buffer solution, quinhydrone, and a platinum wire; when immersed in an unknown solution, a potential difference develops that varies with the pH of the unknown solution; this difference can be made to give the pH; used in pH meters. (05 Mar 2000) |
| central terminal electrode | In electrocardiography, an electrode in which connections from the three limbs (right arm, left arm, and left leg) are joined and led to the electrocardiograph to form the indifferent electrode, theoretically at zero potential for the system. (05 Mar 2000) |
| Clark electrode | An oxygen electrode consisting of the tip of a platinum wire exposed to a thin film of electrolyte covered by a plastic membrane permeable to oxygen but not to water or the electrolyte. When a certain voltage is applied, oxygen is destroyed at the platinum surface; the flow of current is then proportional to the rate at which oxygen can diffuse to the platinum surface from the gas or liquid sample outside the membrane, and is thus a measure of the oxygen pressure in the sample; commonly used to measure oxygen pressure in arterial blood samples.
