What's the difference between ecdysis and endysis?
Ecdysis
Definition:
(n.) The act of shedding, or casting off, an outer cuticular layer, as in the case of serpents, lobsters, etc.; a coming out; as, the ecdysis of the pupa from its shell; exuviation.
Example Sentences:
(1) At the culmination of each molt, the larval tobacco hornworm exhibits a pre-ecdysis behavior prior to shedding its old cuticle at ecdysis.
(2) The time course of hormonal peaks in decapitated females resembles that in starved females during the first post-ecdysial week, suggesting that some as yet unknown regulating mechanism of ECD production lies outside the head.
(3) mortality was high), while the nymphal instars showed an adverse effect on ecdysis and adults which emerged from the treated last nymphal instar were characterized by high mortality, abnormal behaviour and reduced fecundity and viability.
(4) Post-thoracic ligation of animals at ecdysis blocks nucleolar changes as well as the appearance of polyploid nuclei.
(5) The effects of the insect growth regulator diflubenzuron (DFB) were observed on the larval-larval and larval-pupal moulting cycles of Tenebrio molitor, after treatment at ecdysis.
(6) In the hemolymph of the silkworm, Bombyx mori, lectin with hemagglutinating activity against sheep red blood cells increases at larval-larval ecdysis and at spinning stage (Suzuki and Natori, 1983) and is induced by infection with cytoplasmic polyhedrosis virus.
(7) Mature 4th stage microbodies decrease in size before ecdysis to the 5th stage when they atrophy at the same time as the new 5th stage generation arises.
(8) The second factor accelerates ecdysis in nonregenerating animals and appears to be produced in the eyestalks.
(9) We have found that the ability to produce the larval-like ecdysis pattern is retained in the adult.
(10) Our results on regressing Y organs of parasitized crabs are compared with those on regressing ecdysial glands of insects.
(11) In both cases the analyses were carried out from the fourth larval ecdysis to the beginning of spinning.
(12) This induction of precocious ecdysis is always accompanied by an inhibiting effect on regeneration: tiny abnormal regenerates or none are obtained.
(13) The ecdysial glands (Y organs) of the crab Carcinus maenas regress in the presence of an external parasite, Sacculina carcini.
(14) After an amputation close to the pupal ecdysis, fragments are obtained, and these incomplete structures show that the restoration process has ceased.
(15) During the week prior to the terminal ecdysis, developing moths still enclosed within the pupal cuticle produced motor patterns similar to those recorded from adults during flight and shivering.
(16) The declining titer is known to influence the timing of ecdysis, and it was found that the median ecdysis time of females occurs 1 day before that of males even when males and females are synchronized with each other using a developmental marker on Day 14.
(17) After adult ecdysis, the epidermal cells continue to deposit endocuticle.
(18) Argentaffin materials (polyphenols) first appear in these same sites at the time of ecdysis and increase rapidly during the next 24 h. Lipid appears in the lumen of the distal parts of the pore canals (with a patchy distribution) shortly before ecdysis.
(19) An important decrease of the hormone titer is observed at ecdysis.
(20) The pair of epidermally derived Verson's glands on each segment of the tobacco hornworm, Manduca sexta, secretes at ecdysis proteinaceous products which coat the epicuticle.
Endysis
Definition:
(n.) The act of developing a new coat of hair, a new set of feathers, scales, etc.; -- opposed to ecdysis.
