Graafian follicle A fluid-filled, spherical vesicle in the ovary of a mammal, containing an oocyte attached to its wall, and responsible for oestrogen production in. The Graafian follicle is the follicular stage after the first meiotic division but before ovulation. It therefore contains a 2N haploid oocyte.The ovarian cycle - Reproductive system physiology - NCLEX-RN - Khan Academy
It is characterized by a. From Blandau RJ: Growth of the ovarian follicle and ovulation. Prog Gynecol ..
Diagram of the architecture of a typical class 5 graafian follicle.(From Erickson.After ovulation, (luteal phase), the granulosa cells in the wall of the ruptured follicle in the ovary become the corpus luteum. During the luteal phase of the cycle, the corpus luteum secretes progesterone and oestrogen which suppress the secretion of FSH by a negative feedback mechanism on the pituitary so that no further ovulation can occur in that cycle, (Fig.
). The female reproductive organs include the uterus, fallopian tubes, and the ovaries (Fig.
1). Their position, size, and anatomic relations vary considerably with age and the physiologic changes of menstruation, pregnancy, and menopause. Folliculogenesis is the process in which a recruited primordial follicle grows and develops into a specialized graafian follicle with the potential to either ovulate its egg into the oviduct at mid-cycle to be fertilized or to die by atresia. The ultrasound image in Fig. 7 shows the follicle fluid as a black surface.
The recording was made shortly before ovulation.
Since at this moment the cumulus oophorus has detached itself from the granulosa, the oocyte "swims" surrounded by its cumulus cells (so-called corona radiata) in the follicle . The follicular phase is the phase of the estrous cycle, (or, in humans and great apes, the menstrual cycle) during which follicles in the ovary mature.
It ends with schematron.org main hormone controlling this stage is schematron.org are several steps in the process of follicular development that occur in the follicular phase: Initiation, Recruitment and progression, Pre-ovulatory maturation.Ovarian follicle - WikipediaFollicular phase - Wikipedia
