| split renal function test | A study performed to determine various functional parameters of one kidney compared to the contralateral kidney; ureteral catheters are inserted at cystoscopy into the ureter or renal pelvis bilaterally, and simultaneous measurements are made of urine flow rate, insulin, or PAH (if infused), endogenous creatinine, or various urinary solutes. Synonym: differential renal function test, split renal function test. (05 Mar 2000) |

| split-skin graft | A graft of portions of the skin, i.e., the epidermis and part of the dermis, or of part of the mucosa and submucosa, but not including the periosteum. Synonym: partial-thickness graft, split-skin graft. (05 Mar 2000) |
| split-tail | <zoology> A california market fish (Pogonichthys macrolepidotus) belonging to the Carp family. The pintail duck. Source: Websters Dictionary (01 Mar 1998) |
| split-thickness flap | A flap of a portion of the skin, i.e., the epidermis and part of the dermis, or of part of the mucosa and submucosa, but not including the periosteum. Synonym: partial-thickness flap. (05 Mar 2000) |
| split-thickness graft | A graft of portions of the skin, i.e., the epidermis and part of the dermis, or of part of the mucosa and submucosa, but not including the periosteum. Synonym: partial-thickness graft, split-skin graft. (05 Mar 2000) |
| split tolerance | Modification of an immune response to an antigen after prior exposure to that antigen. Synonym: split tolerance. (05 Mar 2000) |
| split-tongued | <zoology> Having a forked tongue, as that of snakes and some lizards. Source: Websters Dictionary (01 Mar 1998) |

| Needles' split cast method | A procedure for placing indexed casts on an articulator to facilitate their removal and replacement on the instrument, the procedure of checking the ability of an articulator to receive or be adjusted to a maxillomandibular relation record. Synonym: Needles' split cast method. (05 Mar 2000) |
| 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.
