ptilinum वाक्य

उदाहरण वाक्य

1. When the adult emerges, the fluid is withdrawn, the ptilinum collapses, and the membrane retracts entirely back inside the head.
2. The inflation of the ptilinum ( using fluid hemolymph rather than air ) creates pressure along the line of weakness in the puparium, which then bursts open along the seam to allow the adult to escape.
3. The defining feature of the Schizophora is the presence of a special structure used to help the emerging adult fly break free of the puparium; this structure is an inflatable membranous sac called the ptilinum that protrudes from the face, above the antennae.
4. In this he identified the divisions of the " Cyclorrhapha ", " Aschiza " and " Schizophora ", a division he based on differences in the frontal region of the head . " Aschiza " have no ptilinum or associated suture, " Schizophora " have both ptilinum and its suture.

6. In Cyclorrhapha Schizophora, a morphological element of particular importance is the presence of the ptilinal suture formed by the resorption of the ptilinum after emergence from the pupa . The suture separates two regions : 1 . the upper one is the frontal region, which has continuity with the apex, the orbital region and the gena : 2 . the lower one, the face or clypeus, contains the insertion of the antennae and ends with the epistomal edge which comprises the upper lip.
