Developmental Plasticity and Evolution
The internal nature of mother-offspring relationships is altered in that in the
panoistic ovary the oocytes are surrounded only by maternal somatic (folliclel
cells, whereas in meroistic polytrophic ovaries the oocyte is nurtured by a cluster
of nurse ...

The Insect Ovary: Ultrastructure, Previtellogenic Growth and ...
3.5.2 Polytrophic meroistic ovaries Meroistic ovaries differ by one important
criterion from panoistic ovarioles. A certain amount of interconnected cystocytes
will be transformed into nurse cells, which can now differentiate their genomes by
...

Chemoecology of Insect Eggs and Egg Deposition
Meroistic. Ovarioles. In insects, the germ cells that receive the information
necessary for the continuation of life arise from pole cells that segregate from the
rest of the single cell layered embryo very early in development. They migrate to
the ...

Physiological Systems in Insects
(B) The telotrophic meroistic ovariole, with a cytoplasmic cord that connects nurse
cells that remain in the germarium with the descending oocyte. (C) The
polytrophic meroistic ovariole, with nurse cells contained within the follicle.

A Dictionary of Entomology
Pertaining to Ovarioles that contain Trophocytes (Nurse Cells). MEROISTIC EGG
TUBE A derived type of Ovary which contains Trophocytes (nutritive cells, nurse
cells) which provide macromolecules (including nucleic acid) that are utilized by
...
Gordon Gordh, David Headrick, 2001
A very restricted RNA metabolism is connected with the condensed state of the
oocyte chromosomes in the meroistic ovary. The RNA synthesis truly reflects the
degree of despiralisation. Thus in Musca and Calliphora after incubation with ...
Transcriptional Role of Nurse Cells The structure of the meroistic egg chamber,
and the observation of cytoplasmic transport from nurse cells to oocyte, suggest
that the maternal transcripts present in the mature egg at fertilization were ...

Gene Activity in Early Development
Two types of meroistic oogenesis are diagrammed in Fig. 5.1(a) and (b), and a
panoistic ovary is portrayed for comparison in Fig. 5.1(c). The chromosomes of
meroistic insect oocytes typically display a condensed structure (some
exceptions ...
Eric H. Davidson, UNKNOWN. AUTHOR, 2012
Two basic morpho-functional categories of insect ovarioles are traditionally
recognized: panoistic and meroistic (BRANDT 1874). In the panoistic ovarioles
all oogonia are transformed into functional gametes (oocytes), whereas in
meroistic ...

Insect Ecology: An Ecosystem Approach
Meroistic ovaries can be subdivided into two types based on the location of
accessory germ cells relative to the oocyte. In polytrophic ovaries, accessory
germ cells maintain short connections and accompany the oocyte as it moves
down the ...
