Hello everyone!

Today in class we mainly talked about the menstrual cycle. Here are some of the notes I took:

Hypothalamus Gland- regulates the secretion of the pituarty gland

Then the Pituitary Gland relapses FSH and LH.

The FSH and LH then stimulate the ovary to produce Estrogen and Progesterone.

WHEN ESTROGEN LEVELS ARE LOW THE HYPOTHALMUS SIMULATES THE PITUITA

RY Gland AGAIN, THIS IS THE PROCESS OF FEEDBACK!

The chart to the side is basically: What leads to the production of what?

Back tracking a bit: When the egg gets released, the corpus lutem is left over. The corpus lutem is the remains of the follicle. The CL secrets the hormones estrogen and mostly progesterone.

Why do we care about the uterine lining?

The egg, if fertilized will attach to the lining.

Contraception:

-Preventing the union of egg and sperm.

Barrier Method:

-Condoms

-Diaphragm

-Vasectomy

Chemical Methods: (prevents gamete formation or kills gametes)

-Pill

-IUD

-Spermicide

Behavioral Changes in Sexual practices:

-Abstinence

-Rhythm

-Withdrawal

Fertilization occurs in the oviduct

-Zygote- fertilized egg

Cell Division begins

- Embryo -1 cell

- Morula-solid ball of 64 cells

- Blastocyst- hollow ball of cells

Have fun!
