(n. pl.) Cast skins, shells, or coverings of animals; any parts of animals which are shed or cast off, as the skins of snakes, the shells of lobsters, etc.
(n. pl.) The fossil shells and other remains which animals have left in the strata of the earth.
Example Sentences:
(1) The cuticle of the gill lamina obtained from exuviae had similar properties.
(2) Nymphal exuviae of Ap, concolor were highly attractive to adult ticks.
(3) In the colonial summer phase, house bees care for the young and keep brood cells clean from feces and exuviae.
(4) The emergence of the Pernyi silkmoth from the pupal exuviae is dictated by a brain-centered, photosensitive clock.
(5) Two hundred larvae were added to each of a number of soil-filled, plastic tubes, which were buried in the field and retrieved after 2, 5, and 7 d. Of 306 pupae or pupal exuviae recovered, 98.1% were in the top 2 cm of mud.
(6) Between cuticles deposited with beta-ecdysone, new formed ducts take place in the theorical imaginal exuvia.
(7) One strain attached in approximately equal numbers to both exuviae and whole specimens.
(8) Results showed that four of five clinical V. cholerae O1 strains and endogenous bacterial flora were attached preferentially to zooplankton molts (exuviae) rather than to whole specimens.
Exuviation
Definition:
(n.) The rejecting or casting off of some part, more particularly, the outer cuticular layer, as the shells of crustaceans, skins of snakes, etc.; molting; ecdysis.
Example Sentences:
(1) During the process of emergence this gas moves into the exuvial space through the adult spiracles and then follows the exuvial fluid into the alimentary canal.
(2) We investigated the involvement of the enzyme, carbonic anhydrase, in the calcification-decalcification processes occurring in the posterior caeca of the midgut of the terrestrial crustacean, Orchestia cavimana, before and after exuviation.
(3) Reduction of the apical cell membrane of the tormogen cell after apolysis permits unrestricted growth of the new hair into the exuvial space.
(4) It was presumed that the stage III larva had exuviated in the human stomach.
(5) In post-exuvial period, we found only weak specific reaction products, thus indicating a reduced active calcium transport as these ions are rapidly reabsorbed down the concentration gradient.
(6) For both ATPases as well as alkaline phosphatase, the specific reaction products were most intense during the pre-exuvial period, i.e.
(7) This enzyme was ultrahistochemically localized throughout the membranes of the caecal epithelium as well as extracellularly, i.e., within pre-exuvial calcareous concretions and postexuvial calcified spherules.
(8) This fluid begins to disappear from the exuvial space approximately 9-10 h before the actual shedding of the integument.
(9) Acetazolamide treatment in vivo inhibited about 50% of the calcium uptake during both pre-exuvial secretion and postexuvial reabsorption.
(10) We argue that the potassium salt solution, formed in the exuvial space (as water presumably follows the actively transported potassium), has three functions (1) to accomplish the gel--sol transformation, (2) to activate the gel enzymes and (3) to buffer the enzyme solution at a pH favourable to the activity of the gel enzymes.
(11) The exuvial side of the pharate pupal integument is usually positive to the haemolymph-side, both in vivo and in vitro, during the period when the moulting fluid is being secreted.
(12) In a normal 32 mM KHCO3 saline, potential difference (PD) is around 10 mV, exuvial side positive, and short-circuit current (SCC) is 15-20 microA cm-2.
(13) Their level is maximum at the time of the exuviation.
(14) This formation associated with a diplosome goes through the duct cell and ends up in the exuvial space.
(15) The ratio of potassium flux toward the exuvial space is higher than that toward the haemolymph, under both open-circuit conditions and short-circuit conditions, demonstrating by the Flux Ratio test that potassium is actively transported across the isolated integument during this secretion period.
