Gyn - Menstral Cycle

Front 1

What are the functions of the Endocrine system?

Back 1

Major regulator, composed of glands that secrete their products (hormones) into the circulatory system (blood stream), regulates metabolism, reproduction, and other functions

Front 2

Hormones control what?

Back 2

menstrual cycle, ovarian cycle and the uterine cycle which includes the changes in the endometrium

Front 3

What are the three main sources of the endocrine system?

Back 3

Hypothalamus (FSH RF, LH RF), pituitary gland (FSH, LH), ovarian axis (estrogen and progesterone)

Front 4

What is the major control center for regulating endocrine function?

Back 4

Hypothalamus

Front 5

What does the Hypothalamus release?

Back 5

Follicle stimulating hormone releasing factor and luteinizing hormone releasing hormone

Front 6

True or False. The Hypothalamus is the regulator of ovulation.

Back 6

True

Front 7

How does the onset of puberty start, and by which gland initiates it?

Back 7

The onset of puberty is started by the pulsatile release of Gonadotropin releasing hormone...initiated by the Hypothalamus.

Front 8

True or false. The pituitary gland regulates the Hypothalamus.

Back 8

False. The Hypothalamus regulates the pituitary gland by stimulating the pituitary to release LH & FSH under the influence of GnRH.

Front 9

What does the pituitary gland secrete?

Back 9

Follicle stimulating hormone and luteinizing hormone.

Front 10

What does FSH do?

Back 10

FSH is responsible for estrogen secretion in the ovaries, follicle maturation, and ripening of the follicles to a graafian follicle.

Front 11

Luteinizing hormone is responsible for what?

Back 11

Stimulates the ovaries and luteinization of the ruptured follicle to form the corpus leutum.

Front 12

What does the Corpus Luteum do?

Back 12

Secretes progesterone and degenerates reducing the progesterone and mensus occurs...if pregnancy then CL continues to secrete progesterone to keep uterine lining in place for the growing embryo.
