| Bourdon tube | A curved and partially flattened tube that tends to straighten out in proportion to internal pressure; used as a transducer to move the pointer of an aneroid manometer. (05 Mar 2000) |
| buccal tube | <dentistry> A small metal part that is welded on the outside of a molar bank. The buccal tube contains a slots to hold archwires, lip bumpers, face-bows and other things your orthodontist uses to move your teeth. (08 Jan 1998) |
| calyx-tube | A tube formed by fusion or cohesion of sepals. Compare: hypanthium. (09 Oct 1997) |

| cardiac tube | The primitive tubular heart in the embryo, before its division into chambers. (05 Mar 2000) |
| Carlen's tube | A double lumen flexible endobronchial tube used for bronchospirometry, for isolation of one lung to prevent contamination or secretions from the contralateral lung, or for ventilation of one lung. (05 Mar 2000) |
| vacuum tube | A glass tube from which the air has been removed, containing two or more electrodes, between which passes an electrical current or spark; used in the production of X-rays, or to control circuits. Previously in wide use, the vacuum tube has been supplanted by transistors in electronic circuits. (05 Mar 2000) |
| gastrostomy tube insertion | A surgical procedure to insert a tube into the stomach for purposes of nutrition.

A thin flexible catheter is inserted into the stomach and then stitched in place. (27 Sep 1997) |
| Geiger-Muller tube | <instrument> An instrument for measuring radioactivity by counting the emission of radioactive particles. It consists of a metallic cylinder, negatively charged, in a tube containing a fine, positively charged wire at its centre; radiations produce ionization of the gas molecules between the cylinder and the wire and result in an electrical discharge independent of the energy of the impinging particle or ray. (05 Mar 2000) |
| geissler tube | <physics> A glass tube provided with platinum electrodes, and containing some gas under very low tension, which becomes luminous when an electrical discharge is passed through it; so called from the name of a noted maker in germany. It is called also Plucker tube, from the German physicist who devised it. Source: Websters Dictionary (01 Mar 1998) |
| ventral plate of neural tube | The ventral division of the lateral walls of the neural tube in the embryo; it contains neuroblasts giving rise to somatic and visceral motor neurons. Synonym: lamina basalis, basal plate of neural tube, lamina ventralis, ventral plate of neural tube. (05 Mar 2000) |
| Venturi tube | A tube with a specially streamlined constriction to minimise energy losses in the fluid flowing through it while maximizing the fall in pressure in the constriction in accordance with Bernoulli's law; the basis of the Venturi meter. (05 Mar 2000) |
| Martin's tube | A drainage tube with a cross piece near the extremity to keep it from slipping out of a cavity. (05 Mar 2000) |
| germ tube | A young hypha growing out of a yeast cell or spore, the beginning of a mycelium; also used as a rapid test for differentiating Candida albicans from other Candida species. (05 Mar 2000) |
