What is the definition of embryonic development?
It begins after fertilization.
How do cells contribute to the formation of different body parts during embryonic development?
By growing and differentiating into specialized types.
What process do cells undergo during embryonic development?
Cells grow and differentiate into specialized types.
What happens during embryonic development after fertilization?
A single cell divides repeatedly.
What is the name of the process shown in the image?
Bilamin
What does the morula develop into?
A hollow ball called a blastocyst
What is cell division?
Cells making copies of themselves
What is the role of the hypoblast?
It will support the embryo
What does the inner layer of the blastocyst form?
Hypoblast
What is the function of the trophoblast?
It will form the placenta
What are the stages of embryonic development?
Fertilized cell becomes morula
Morula develops into blastocyst
Outer layer forms trophoblast (placenta)
Inner layer forms hypoblast (supports embryo)
Bilaminar disk develops on Day 12
What is the name of the process shown in the image?
Bilamin
How many cell layers are in the bilaminar disk?
Two cell layers
What is the purpose of the Bilamin process shown in the image?
To divide and replicate the cell
What is the name of the structure shown on the right side of the image?
Gastrula
What is the relationship between cell division and differentiation?
Cell division increases cell number
Differentiation determines cell type
Together, they form various organs
What is the opening of the archenteron called?
Blastopore
What is the name of the opening in the gastrula?
Blastopore
What cavity is formed during the invagination of the blastula?
Archenteron
What is differentiation in cells?
Cells deciding what type to become
What develops on Day 12 of embryonic development?
A bilaminar disk
What are the three main layers of the gastrula shown on the right side of the image?
Ectoderm, Endoderm, Archenteron
What does the outer layer of the blastocyst become?
Trophoblast
What are the key differences between the blastula and gastrula stages of embryonic development?
Blastula:
Hollow ball of cells
Has a blastocoel cavity

Gastrula:
Has three germ layers (ectoderm, endoderm, mesoderm)
Has an archenteron (primitive gut) with a blastopore opening
What organ systems arise from the ectoderm layer?
Hair, nails, skin, nervous system
How does the blastula develop into the gastrula?
Cells on one side of the blastula invaginate (fold inward)
This forms the archenteron (primitive gut) and the three germ layers (ectoderm, endoderm, mesoderm)
The blastopore becomes the opening of the archenteron
What is the name of the cavity in the blastula?
Blastocoel
What nutrients are important for embryonic development?
Key vitamins and minerals
Why is maternal health important during pregnancy?
It is essential for proper embryonic development
Which germ layer is the inner layer?
Endoderm
What role do genetic factors play in embryonic development?
They determine the body's blueprint
What is the name of the membrane derived from the blastocyst cavity?
Chorion
What does proper embryonic development involve?
Cells dividing and differentiating into tissues
Why is proper embryonic development important?
It is crucial for a healthy life
What are congenital conditions?
Defects present from birth
What influences embryonic development?
Genetic factors, nutrients, toxins, maternal health
How do differentiated cells contribute to the body?
They form different organs like heart and brain
What lifestyle factors can ensure healthy embryonic development?
Proper nutrition and a healthy lifestyle
What will the three germ layers develop into?
Specific adult tissues and organs
What is formed during embryonic development?
All the organs and tissues of the baby.
