The bit of a key. 7. <machinery> A plate or thin portion, continuous or perforated, connecting stiffening ribs or flanges, or other parts of an object. Specifically: The thin vertical plate or portion connecting the upper and lower flanges of an lower flanges of an iron girder, rolled beam, or railroad rail. A disk or solid construction serving, instead of spokes, for connecting the rim and hub, in some kinds of car wheels, sheaves, etc. The arm of a crank between the shaft and the wrist. The part of a blackmith's anvil between the face and the foot. 8. <ophthalmology> Pterygium; called also webeye. 9. <anatomy, ornithology> The membrane which unites the fingers or toes, either at their bases, as in man, or for a greater part of their length, as in many water birds and amphibians. 10. <zoology> The series of barbs implanted on each side of the shaft of a feather, whether stiff and united together by barbules, as in ordinary feathers, or soft and separate, as in downy feathers. See Feather. <medicine> Pin and web, the system of braces connecting the flanges of a lattice girder, post, or the like. Origin: OE. Web, AS. Webb; akin to D. Web, webbe, OHG. Weppi, G. Gewebe, Icel.

| terminal web | <cell biology> The cytoplasmic region at the base of microvilli in intestinal epithelial cells, a region rich in microfilaments from the microvillar core and from adherens junctions, in myosin and in other proteins characteristic of an actomyosin motor system. (13 Jan 1998) |
| trophic web | <biology> Feeding relationships in communities that determine the flow of energy and materials from plants to herbivores, carnivores and scavengers. (09 Oct 1997) |
| alveolar dead space | The difference between physiologic dead space and anatomical dead space; it represents that part of the physiologic dead space resulting from ventilation of relatively underperfused or nonperfused alveoli; it differs specifically in being placed so as to fill and empty in parallel with functional alveoli, rather than being interposed in the conducting tubes between functional alveoli and the external environment. (05 Mar 2000) |
| anatomical dead space | The volume of the conducting airways from the external environment (at the nose and mouth) down to the level at which inspired gas exchanges oxygen and carbon dioxide with pulmonary capillary blood; formerly presumed to extend down to the beginning of alveolar epithelium in the respiratory bronchioles, but more recent evidence indicates that effective gas exchange extends some distance up the thicker-walled conducting airways because of rapid longitudinal mixing. Compare: alveolar dead space, physiologic dead space. Synonym: anatomical airway. (05 Mar 2000) |
| antecubital space | The fossa in front of the elbow, bounded laterally and medially by the humeral origins of the extensors and flexors of the forearm, respectively, and superiorly by an imaginary line connecting the humeral condyles. Synonym: fossa cubitalis, antecubital space, chelidon, triangle of elbow. (05 Mar 2000) |
| anterior clear space | On lateral chest radiographs, the region dorsal to the sternum and ventral to the ascending aorta. Synonym: anterior clear space. (05 Mar 2000) |
