What composes a Follicle?
|
Ovum and Supporting cells
|
|
|
What happens to the Follicle during ovulation?
|
One of the two ovarian follicles ruptures to release an ovum which enters the fallopian tube.
|
|
|
Which two structures does the fallopian tube connect together and what is it the site for?
|
Fallopian tube connects the ovaries and uterus.
It is the site of fertilization. |
|
|
Where does fertilization occur?
|
Fallopian Tube
|
|
|
What are the terms for the outer and inner membrane of the ovum?
|
Outer Membrane: Corona Radiata
Inner Membrane: Zona Pellucida |
|
|
What happens during fertilization with respect to the ovum membranes?
|
The degradative enzymes from the Acrosome degrade the Corona Radiata and the Zona Pellucida.
|
|
|
What marks the completion of fertilization?
|
When the nuclei of the sperm and ovum have fused to form a zygote. (single diploid cell)
|
|
|
What happens with the zygote after fertilization?
|
It travels to the uterus to implant in the Endometrial Tissue.
|
|
|
Endometrial Tissue is the site for what?
|
Implantation of the Zygote straight after fertilization.
|
|
|
What is a placenta comprised of?
|
A complex mix of embryonic and maternal tissue which develops at the site of implantation.
|
|
|
What is transferred into and out of the Placenta?
|
1) Nutrients from mother to fetus.
2) Waste from fetus to mother. 3) Gases (O2 and CO2) between mother and fetus. |
|
|
When does the Placenta develop?
|
During Implantation of the Zygote into the Endometrial Tissue
|
|
|
Corona Radiata exists in what type of organisms?
|
Mammalian eggs
|
|
|
Which structure allows for species-specific binding of sperm in amphibians?
|
Vitelline Membrane of the egg yolk
|
|
|
Plasma Membrane seen in human eggs?
|
Yes it encloses the cytoplasm
|
|
|
What is the Corpus Luteum?
|
The remains of the follicle from which the egg is released at the time of ovulation.
