Q

What are the parts (in order) of fertilization?

A
  1. ) intercourse
  2. ) sperm cells swim past the cervix, through the uterus, and into one of the oviducts
  3. ) one sperm will combine with the egg cell (fertilization) Zygote is produced
  4. ) Two layers of cells around the egg cell prevent more than one sperm to fertilize it
  5. ) zygote will produce new body cells by mitosis and implant into the lining of the uterus. (becomes placenta)

Q

Cleavage?

A

the division of cells by mitosis in the early stages of embryonic development. The zygotes of many species undergo rapid cell cycles with no significant growth, producing a cluster of cells the same size as the original size.

Q

Blastula?

A

an early stage of embryonic development that is produced by cleavage of a fertilized ovum(egg) and consists of a spherical layer of around 128 cells surrounding a central fluid-filled cavity called the blastocoel.

21
Q

Gastrula?

A

as the zygote continues to grow and some of the cells in the blastula move inward. This stage is called gastrulation

22
Q

3 Germ Layers?

A

develop different part of baby’s body

23
Q

Differentiation?

A

the process by which cells produce 3 germ layers. These germ layers will develop the different parts of the body

24
Q

When are these 3 Germ Layers develop?

A

when different genes are activated and produce specific proteins

25
Q

What happens in Gene Expression?

A

When activated, genes are expressed during development.

26
Q

What are the 3 Germ Layers?

A

Ectoderm, Mesoderm, Endoderm

27
Q

Where are all of the germ layers located in?

A

Gastrula

28
Q

Where is the ectoderm’s layer and what is its development?

A

Outer

the layer of cells that develops into the skin and nervous system

29
Q

Where is the Mesoderm’s layer and what is its development?

A

Middle
the layer of cells that develops into the muscular system, skeletal system, circulatory system, excretory system, and respiratory system.

30
Q

Where is the Endoderm’s layer and what is its development?

A

Inner

the layer of cells that develop into the digestive tract

31
Q

Placenta?

A

for 9 months, feeds and nourishes the fetus while also disposing of toxic waste.

32
Q

Umbilical Cord?

A

tube that connects a developing fetus to the placenta

33
Q

Amnion?

A

a fluid-filled sac that surrounds and protects the embryo

34
Q

chorion?

A

the membrane that exists during pregnancy between the developing fetus and mother. It surrounds the embryo and transfers nutrients from mother’s blood to baby’s blood.

35
Q

Allantois?

A

sac-like structure is primarily involved in neutron and excretion. Collects liquid waste from the embryo, as well as to exchange gases used by the fetus

36
Q

What are the months of the 1st Trimester?

A

Month 1-3

37
Q

What are the months of the 2nd Trimester?

A

Month 4-6

38
Q

What are the months of the 3rd Trimester?

A

Month 7-9

39
Q

What happens in the first trimester?

A

All the major organ system of the embryo grows and develops into a fetus

40
Q

What happens in the second trimester?

A

the fetus grows for three months. By the end of this trimester, the fetus begins to move.

41
Q

What happens in the third trimester?

A

The mass of the fetus more than triples. The fetus kicks, stretches, and moves freely. At the end of the 9th month, the fetus is ready to be born (labor)

42
Q

When can the sex of the fetus be identified?

A

2nd trimester

end of the 4th month

43
Q

When can the mother feel fetal movement?

A

2nd trimester

end of the 5th month

44
Q

What is Reproductive Technology?

A

Scientific methods that help people reproduce artificially

45
Q

What do these methods help?

A

couples who are having trouble reproducing

46
Q

Artificial Insemination?

A

the process by which sperm is placed into a female’s uterus, or cervix artificially with a needle less syringe
The sperm will swim up the uterus and into the oviduct looking for the egg cell to fertilize and begin pregnancy

47
Q

In Vitro Fertilization?

A

a process by which an egg is fertilized by sperm outside the body
involves women removing an egg or eggs from the woman’s ovaries and sperm fertilizes them in a liquid lab
The fertilized egg is cultured for 2-6 days in a growth medium and is then implanted in the same or another woman’s uterus, with the intention of establishing a successful pregnancy

48
Q

Surrogacy?

A

a method of assisted reproduction where a woman agrees to become pregnant for the purpose of giving birth to a child for others who can’t conceive

49
Q

Embryonic Stem Cell Research?

A

the process of using stem cells from an embryo and insert them with DNA
these cells have the ability to differentiate into any of the body cells that the scientist wants.
Scientists just insert the DNA they want to reproduce and the stem cells will transform into the desired cells.

50
Q

Birth Control?

A

the method of preventing pregnancy

51
Q

What are examples of Contraception?

A

Abstinence, condoms, birth control pills

52
Q

Do these methods prevent pregnancy and STD transmissions?

A

prevents pregnancy but not STD
