A review of echinoderm oogenesis

Journal of Electron Microscopy Technique, 1990
AbstractThis review of the anatomical, histological, biochemical, and molecular biological literature on echinoderm oogenesis includes the entire developmental history of oocytes; from their inception to the time they become ova. This is done from a comparative perspective, with reference to members of the five extant echinoderm classes; crinoids ...

The Role of Nourishment in Oogenesis

Annual Review of Entomology, 1996
Sexual receptivity is female behavior that allows or helps a male to fertilize her eggs; through this behavior, females play an active role in reproduction. Multiple signals may be used for receptivity or unreceptivity. Insect species exhibit three ontogenetic patterns of receptivity: cyclic, in which females alternately become receptive and ...

Oogenesis in adult prosimians

Development, 1967
ABSTRACT It has been claimed that new germ cells are formed after maturity in certain female prosimians. A histological study was made of the ovaries of adults of four of these species (Galago crassicaudatus, G. demidoffi, Perodicticus potto and Loris tardigradus lydekkerianus), and of juvenile specimens of Loris.

Cytoplasmic Inclusions in Oogenesis

1965
Publisher Summary This chapter focuses on the cytoplasmic inclusions in oogenesis, and discusses the structure and functions of the Golgi apparatus and mitochondria in eggs and their role in vitellogenesis. Investigation of Golgi apparatus in eggs is beset with special difficulty because of the presence of yolk, which becomes enormous in quantity as ...

Histochemistry of Lipids in Oogenesis

1960
Publisher Summary This chapter presents the histochemistry of lipids in oogenesis. A conclusion that has emerged from the investigations of Nath and his co-workers is that the synthesis of triglyceride globules in the oocytes occurs in three stages.
