A follicle that has recently released an egg is called a ​ (a)   . This follicle releases a hormone called ​ (b)   which ​ (c)   the shedding of the uterine lining, known as ​ (d)   .​ ​

Two crucial hormones that are released from the pituitary gland are known as LH (luteinizing hormone) and ​ (a)   . In women, this hormone is essential for the development of follicles and it triggers the release ​ (b)   in the ​ (c)   ​.

Choose from the below words
FSH (follicle stimulating hormone)
GnRH (gonadotropin-releasing hormone)
estrogen
progesterone
ovary
fallopian tubes
uterus
11.

An ​increase in ​ (a)   causes an ​ (b)   in ​ (c)   , a hormone that causes ovulation to occur. ​ After ovulation, the ruptured follicle known as a corpus luteum (that has released an ovum, matured egg), releases a hormone called ​ (d)   . This hormone prevents the shedding of the uterine lining. The menstrual cycle is repeated when levels of this same hormone drops, causing an increase in ​ (e)   , which gives nutrients needed for follicles to grow. Estrogen will be released from these growing follicles, eventually decreasing the levels of FSH hormone. (Reread from the top to see what else estrogen does to continue the menstrual cycle)

Choose from the below words
increase
LH (luteinizing hormone)
estrogen
progesterone
FSH (follicle stimulating hormone)
decrease
12.

Match the events of the menstrual cycle to the days they occur.

Categorize the following

The hypothalymus released GnRH which triggers LH and FSH to be released.

LH and FSH stimulate the development of the primary follicle in the ovary.

The follicle secretes estrogen.

Lack of progesterone causes the breakdown of the endometrium, causing mensuration.

Estrogen causes the thickening of the endomentrium.

The follicle is nearly mature, releasing high levels of estrogen causing a surge in LH.

LH causes ovulation to occur.

The ruptured follicle becomes the corpus luteum.

The corpus luteum release so much progesterone that estrogen levels drop.

High progesterone levels maintain the thickness of the endometrium.

Steadily, progesterone levels begin to drop, causing the endometrium to get ready to shed.

The corpus luteum stops producing progesterone and becomes a scar tissue, the corpus albicans.
