Bulb definitions

Webster's 1828 Dictionary

BULB, n. [L. bulbus, a bulb or round root.] A round body, applied to many objects. But in botany, it is appropriately a bud formed under ground, upon or near the roots of certain herbaceous plants, which are hence called bulbous plants, as the tulip, onion and lily. The bulb under ground is what the bud is upon the stem or branches, a hybernacle or winter receptacle of a future plant, containing the plant in embryo, covered with a bark or rind, generally consisting of scales placed over each other, to defend the tender rudiments of the plant from cold and other external injuries. A bulb is scaly in the lily, solid in the tulip, coated in the onion, and jointed in the tuberous moschatel.
BULB, v.i. To bulb out is to project or be protuberant. [Little used.]

WordNet (r) 3.0 (2005)

2: electric lamp consisting of a transparent or translucent glass housing containing a wire filament (usually tungsten) that emits light when heated by electricity [syn: light bulb, lightbulb, bulb, incandescent lamp, electric light, electric-light bulb]
3: a rounded part of a cylindrical instrument (usually at one end); "the bulb of a syringe"
4: anything with a round shape resembling a teardrop
5: lower or hindmost part of the brain; continuous with spinal cord; (`bulb' is an old term for medulla oblongata); "the medulla oblongata is the most vital part of the brain because it contains centers controlling breathing and heart functioning" [syn: medulla oblongata, medulla, bulb]
6: a rounded dilation or expansion in a canal or vessel or organ
