(n.) The solid generated by the rotation of a parabola about its axis; any surface of the second order whose sections by planes parallel to a given line are parabolas.
Example Sentences:

(2) The sinuses are subsequently arranged into 4 classes, according to their similarity to solids of revolution such as: semi-ellipsoid (class a: 15% of specimens); paraboloid (class b: 30%); hyperboloid (class c: 47%) and cone (class d: 8%).
(3) In normal adult eyes and in eyes 21 days after lens removal, the paraboloid portion of the photoreceptor inner segments, and in some cases the perinuclear cytoplasm of the photoreceptor cells, contained the antigen.
(4) The present study suggests that the chick paraboloid not only is a field for active glycogen metabolism, but also becomes a storage of glycogen.
(5) A comparison of salmonella findings and E. coli titre showed that with increasing E. coli contamination the proportion of positive salmonella findings also increased (paraboloid curve).
(6) Double cones consist of a larger chief member which shows a thin tapering outer segment, a large heterogeneous oil droplet and a prominent paraboloid.
(7) Histamine-like immunoreactivity was localized within paraboloids of certain cone photoreceptors by use of two different antisera directed against histamine.
(8) Branching glycosyltransferase seemed to appear after phosphorylase was activated and these enzymes became higher in their activity with the differentiation in the paraboloid in the fetal and early postnatal periods.
(9) Native glycogen in the paraboloid stained brown, while histochemically synthesized polyglucose stained brown or purple.
(10) Overproduction of polyglucose particles was not found in the paraboloid of the retina incubated in the medium in vivo.
(11) Glycogen synthetase and phosphorylase activities in the paraboloid glycogen of the accessory cone of the chick retina were studied electron histochemically, while the paraboloid glycogen was observed by electron microscopy.
(12) Some of the paraboloid of the accessory cone of the chick retina contained abundant glycogen granules, but some showed no glycogen granules.
(13) Rod inner segments display an ellipsoid but no oil droplet or paraboloid.
(14) Polyglucose particles synthesized by phosphorylase activity in the chick paraboloid were located in the cytoplasmic matrices and expanded them widely.
(15) These enzyme activities appeared in the cytoplasmic matrices of the developing paraboloid in the photoreceptor inner segment almost simultaneously at the 17th day of incubation.
(16) These results show that (i) the shape of a fine tip is not conical but resembles more closely a paraboloid of revolution, and (ii) for this shape to be maintained throughout growth, accretion (rate of mass uptake per unit area) cannot everywhere be the same on the surface of the tip but must decrease as the diameter increases.
(17) A delay in formation of ellipsoid and paraboloid occurred, especially in membrane discs of the external segment of photoreceptor.
(18) Preincubation of eyecups in Ringer's containing 10 microM histamine selectively increased the immunoreactivity of these photoreceptor paraboloids.
