Describe the overall process of early embryonic development, including cell division of the fertilized oocyte, formation of the blastula, and gastrulation. Some important terms that you will learn include oocyte, sperm, fertilization, zygote, cleavage, morula, blastocyst, trophoblast, cytotrophoblast, syncytiotrophoblast, chorion, placenta, inner cell mass (embryoblast), bilaminar disc, epiblast, amnion, and hypoblast.
-OOCYTE is taken out of the ovaries and is picked up into the uterine tubes (this is called ovulation when leaving ovaries). The OOCYTe and Sperm come together in holy matrimony. When the OOCYTE gets married to the sperm, she changes her name since that is what normally happens (fertilization is OOCYTe and sperm coming together). She is now called zygote. Fertilization is where we mark day one. Zygote now has to do cell division. It goes from 2, to 4, to 8, etc cells. This process of cell division is known as cleavage. Around 16 cells, it is no longer called a zygote, but now a morula. That morula will keep undergoing cell division until it gets to 100 cells and then it will be called blastocyst. The blastocyst is made up of 2 important parts. One is the outer shell called the trophoblast and the other is a mass of cells called the embryoblast (inner cell mass). The blastocyst implants inside of the uterine wall (implantation). -the embryoblast builds the embryo. BLAST=BUILDS, the trophoblast becomes the fetal half of the placenta (Chorion) -placenta=fetal portion + maternal portion come together (fetal portion = chorion which derives from trophoblast) -trophoblast divides into two layers: cytotrophoblast and syncytiotrophoblast (these help form the chorion and later the placenta) -Inner Cell Mass divides into two layers: epiblast and hypoblast - the epiblast becomes the embryo and amnion -epiblast lines the amnion, hypoblast lines the yolk sack

Explain the various functions of epithelial tissue (where it is found and what it does)
Highly cellular, therefore minimal extracellular matrix (this means that there are so many cells, and because there are so many, there is not much space between them) Polarity, therefore tissue has an apical and basal surface (since the top part of the cells are different from the bottom part [like north and south pole, they are different], there is the apical [top part and superficial part] and basal surface.) Attachment to a basement membrane (because it is polar, it has two parts, and the basal part attaches to the basement membrane) Avascular (no blood vessels, which means if we were to cut into the epithelial tissue it would not bleed) Regeneration (if gets cut, will grow back quick)
