What is the acrosome?

Explain the capacitation & acrosome reaction in sperm
The acrosome contains enzymes that degrades the outside cell wall of the oocyte

Explain the 6 steps of fertilization
Once a sperm enters the egg, Ca++ activates and hardens the outside layer to prevent other sperm from entering

Explain Ovulation, fertilization, implantation in the fallopian tubes


What does an increase in estrogen do to the endometrial tissue?
Starts the remodelling process
Explain the steps of Placental development: adhesion and invasion


Explain the steps of Placental development: invasion and implantation


What is preeclampsia?
Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys.

What is placenta accreta?
Placenta accreta is a serious pregnancy condition that occurs when the placenta grows too deeply into the uterine wall.

Trophoblastic nutrition is critical early on….and dependent upon what hormone?

At what point in pregnancy does the placenta become functional for fetus nutrition and support?


What are the functions of the placenta?


What factors increase drug transfer in across placental barrier?

What is hCG-what are it’s functions? When is it important?


How do the roles of hCG, estrogen, and progesterone change throughout pregnancy?
hCG’s begins it’s decline at 2 mos and the corpus luteum begins to secrete less progesterone and estrogen. However, by 7th week of pregnancy, the placenta had already begun to gradually take over the endocrine function of corpus luteum.

Roles of estrogen and progesterone throughout pregnancy?
