| auditory tube | A tube leading from the tympanic cavity to the nasopharynx; it consists of an osseous (posterolateral) portion at the tympanic end, and a fibrocartilaginous (anteromedial) portion at the pharyngeal end; where the two portions join, in the region of the sphenopetrosal fissure, is the narrowest portion of the tube (isthmus); the auditory tube enables equalization of pressure within the tympanic cavity with ambient air pressure, referred to commonly as "popping of the ears". Synonym: tuba auditiva, tuba auditoria, eustachian tube, guttural duct, otopharyngeal tube, otosalpinx, pharyngotympanic tube, salpinx, tuba acustica, tuba eustachiana, tuba eustachii.

| basal lamina 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) |

| 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. In this procedure, a small incision is made in the left upper quadrant of the abdomen while the patient is under general anaesthesia (can also be performed with a local anaesthetic). 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.
