What does the anterior pituitary gland release about the time of ovulation?
The anterior pituitary gland releases luteinizing hormone (LH) about the time of ovulation. LH surge triggers the release of mature eggs from the ovary and stimulates the production of progesterone in the ovary.
Stimulates LH release by anterior pituitary?
inhibin and estrogen in females, inhibin and testosterone in males
How does GnRH get from the hypothalamus to the anterior pituitary and what effects does it have on the pituitary?
The hypophysial portal system carries gonadotropin-releasing hormone (GnRH) from the hypothalamus to the anterior pituitary. It stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.
What stimulate estrogen?
Oestrogen stimulates the hormone LH. LH is secreted in pituitary gland and stimulates the release of an egg
What hormone stimulates the gonads?
The release of Follicle-stimulating hormone(FSH) and Luteinizing hormone(LH) stimulates cells in the testes to produce Testosterone.
What stimulates the secretion of estrogen?
Oestrogen stimulates the hormone LH. LH is secreted in pituitary gland and stimulates the release of an egg
What structure secretes LH?
LH is produced in the anterior pituitary gland.
Which hormone stimulates egg release?
Ovulation, that is a process by which a mature ovarian follicle releases an ovum, is triggered by the spike in the amount of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) released from the anterior lobe of the pituitary gland.
The surge in LH secretion from the anterior pituitary that causes ovulation can be partially explained by the?
positive feedback of estradiol that increases the release of LH
How can FSH be the cause of not producing eggs?
FSH, secreted by the Pituitary gland,stimulates the secretion of Oestrogen from the ovaries, Oestrogen in turn stimulates the secretion of LH by the pituitary and inhibits the secretion of FSH, LH then stimulates ovulation (the release of an egg). Without FSH this chain reaction does not happen.
What hormone stimulates the development of a follicle in the ovary?
Leutinizing hormone (LH) is the hormone that stimulates a follicle to develop a mature egg. LH and follicle stimulating hormone (FSH) work together to regulate egg production and ovulation in females.
FSH and LH are two hormones produced by the?
Pituitary Gland
