graafian follicles การใช้

• Before ovulation, the Graafian follicles reach a length of at least.
• Once matured, these are called Graafian follicles.
• On day 14, the LH surge causes a Graafian follicle to surface the ovary.
• In addition, follicles that have formed an antrum are called antral follicles or Graafian follicles.
• In human embryogenesis, the theca cells form a corpus luteum after a Graafian follicle has expelled its secondary oocyte arrested in second meiosis.
• Tertiary vesicular follicles ( also called " mature vesicular follicles " or " ripe vesicular follicles " ) are sometimes called Graafian follicles ( after Regnier de Graaf ).
• The mature stage of the ovarian follicle is called the Graafian follicle in his honour, although others, including Fallopius, had noticed it previously but failed to recognize its reproductive significance.
• Apart from fibrinolysis, plasmin proteolyses proteins in various other systems : It activates collagenases, some mediators of the complement system and weakens the wall of the Graafian follicle ( leading to ovulation ).
• Professor John Francis Kerin s postgraduate ( phd ) thesis was titled  On the endocrine function of the human graatian follicle, submitted in December 1977 to the Department of Obstetrics and Gynaecology at the Queen Elizabeth Hospital, The University of Adelaide, a thesis submitted in fulfilment of the requirements for the degree of Doctor of Medicine in which his aim was to obtain an  understanding of the changing cyclical relationship which exists between the theca and granulosa cells of the isolated human Graafian follicle, in vitro, with respect to its ability to produce the three basic classes of sex steroids, namely the androgens, oestrogens and progestins and to  critically examine factors controlling human ovarian follicle behaviour, in the hope of achieving a better understanding of female ovarian function
