| mechanical ventilator | <apparatus> Mechanically assisted breathing using a electrically powered device that forces oxygenated air into the lungs and then allow time for passive exhalation of air. (27 Sep 1997) |
| mechanical vertigo | Vertigo caused by continued rotation or vibration of the body. (05 Mar 2000) |
| viscous mechanical coupling | <cell biology> Method by which adjacent cilia are synchronised in a field. Coupling is through the transmission of mechanical forces, rather than of a synchronising signal. (18 Nov 1997) |
| controlled mechanical ventilation | Artificial ventilation in which all inspirations are provided by positive pressure applied to the airway. Synonym: continuous positive pressure breathing, continuous positive pressure ventilation, intermittent positive pressure breathing, intermittent positive pressure ventilation. (05 Mar 2000) |
| stage mechanical | <microscopy> A small fixture, either built into the light microscope stage or attached separately, it holds the specimen slide and has two horizontal screw adjustments at right angles to each other. The screw motions permit the specimen to be moved as desired. The quantitative type has vermer scales for reading the amount of displacement to 0.1 mm. This stage is sometimes called the traversing stage. (05 Aug 1998) |
| stress, mechanical | A purely physical condition which exists within any material because of strain or deformation by external forces or by non-uniform thermal expansion; expressed quantitatively in units of force per unit area. (12 Dec 1998) |
| tubelength mechanical | <microscopy> This distance is measured from where the objective screws on to where the eyepiece fits in. The American standard mechanical tubelength is 160 mm. For Leitz objectives it was once 170 mm. (05 Aug 1998) |
| uniform mechanical code | (UMC) A code sponsored by the International Association of Plumbing and Mechanical Officials and the International Conference of Building Officials, adopted and amended by the Oregon Department of Commerce. The UMC contains requirements for the installation and maintenance of heating, ventilating, cooling, and refrigeration systems. (05 Dec 1998) |
| annulospiral organ | One of two types of sensory nerve ending associated with a neuromuscular spindle (the other being the flower-spray ending); after entering the muscle spindle, the fibre divides into two flat ribbon-like branches that wind themselves in rings or spirals about the intrafusal muscle fibres. Synonym: annulospiral organ. (05 Mar 2000) |
| auditory organ | Archaic term for gustatory organ. (05 Mar 2000) |
| bojanus organ | <zoology> A glandular organ of bivalve mollusca, serving in part as a kidney. Origin: From Bojanus, the discoverer. Source: Websters Dictionary (01 Mar 1998) |
| vestibular organ | Collective term for the utricle, saccule, and saemicircular ducts of the membranous labyrinth, each having a single patch of ciliated receptor epithelium innervated by the vestibular nerve: macula of sacculus, macula of utriculus, and cristae of the saemicircular ducts. (05 Mar 2000) |
| vestibulocochlear organ | The external, middle, and internal ear. Synonym: organum vestibulocochleare. (05 Mar 2000) |
| vestigial organ | A rudimentary structure in humans corresponding to a functional structure or organ in the lower animals. (05 Mar 2000) |
