Graafian follicle

This secretory structure is known as the graafian follicle.

Once matured these are now called Graafian follicles.

An antral follicle is also called a Graafian follicle.

All the granulosa cells in a Graafian follicle are in fact a clone.

The graafian follicle arises from a tiny microscopic seed known as a primordial follicle.

Day fourteen, ovulation, 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.

An antral follicle (or Graafian follicle) is an ovarian follicle during a certain latter stage of folliculogenesis.

A stigma in mammalian reproductive anatomy refers to the area of the ovarian surface where the Graafian follicle will burst through during ovulation and release the ovum.

In human embryogenesis, the theca cells form a corpus luteum after a Graafian follicle has expelled its secondary oocyte arrested in second meiosis.

Days fifteen to twenty-eight, the Post-ovulatory stage, the Graafian follicle that once held the ovum is now called the corpus luteum, and it now secretes estrogen.

On cut-section, histology reveals reticular, trabecular areas with interstitial haemorrhage and Call-Exner bodies-small cyst like spaces interspersed within a graafian follicle.

High levels of BMP-6 mRNA were present in oocytes of all Graafian follicles, both healthy and atretic (Fig.

Wimsatt W. A., Kallen F. C. The unique maturation response of the graafian follicles of hibernating vespertilionid bats and the question of its significance.

The mature stage of the ovarian follicle is called the Graafian follicle in his honour, although others, including Fallopius, had noticed the follicles previously (but failed to recognize its reproductive significance).

Tertiary vesicular follicles (also called "mature vesicular follicles" or "ripe vesicular follicles") are sometimes called Graafian follicles (after Regnier de Graaf).

The follicular cyst of ovary, or graafian follicle cyst, or follicular cyst is a type of functional simple cyst, and is the most common type of ovarian cyst.

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).

The rise in FSH levels recruits five to seven tertiary-stage ovarian follicles (this stage follicle is also known as a Graafian follicle or antral follicle) for entry into the menstrual cycle.

These cuboidal granulosa cells, also known as the granulosa radiata, form more layers throughout the maturation process, and remain attached to the zona pellucida after the ovulation of the Graafian follicle.

BMP-3 mRNA expression was present in the TIC of healthy Graafian follicles and in the theca lutein cells (TLC) of the CL-I at DI 1100 h (Table 1).

The term Graafian follicle followed the introduction of the term ova Graafiana by Albrecht von Haller who like De Graaf still assumed that the follicle was the oocyte itself, although De Graaf realised the ovum was much smaller.
