What is the trophoblast responsible for forming?
placental tissue
What is a choriocarcinoma?
A choriocarcinoma is type of cancer germ cell containing trophoblast cells.
What is it when something develops?
When something develops, there are usually certain changes to that effect.
What structure develops into the vertebrate spinal cord?
The notochord develops into the vertebrate spinal cord.
The intestinal tract develops from which embryonic germ layer?
It develops from the endoderm germ layer
What is the trophoblast responsible for forming?
placental tissue
What structures gives rise to the placenta a. Inner cell mass c. Epiblast e. Yolk sac b. trophoblast d. hypoblast?
Trophoblast
Is trophoblast is present even as germ layer formation is occurring in human?
If your question is 'Is the trophoblast present during germ layer formation (i.e. gastrulation) ?' then the answer is YES
What is the part of the blastocyst that promotes implantation and produces hCG?
trophoblast
What is the difference between chorion and trophoblast?
amnion is amnion, chorion is chorion
What is the double walled membrane that contains the blastocyst called?
Amniotic sac
What is a choriocarcinoma?
A choriocarcinoma is type of cancer germ cell containing trophoblast cells.
Which blastocyst structure becomes the chorion and cooperates with uterine tissues to perform the placenta?
trophoblast
What is the earliest implantation bleeding occurs?
Implantation can sometimes cause a bit of spotting or bleeding, known as implantation bleeding. Implantation bleeding is a small amount of bleeding in the uterus that occurs when the egg implants into the uterus. A specific tissue, known as trophoblast, develops from the fertilized egg and it surrounds it. It is what attaches the egg to the inside of the uterus, and actually eats its way into the uterus. The trophoblast actually pulls the egg to the inside of the endometrium. Trophoblast even invades the mother's blood vessels and diverts her blood to the fertilized egg. Sometimes, this blood will leak and this causes implantation bleeding. Thus, it is possible that it can be as many as 5 to 14 days between the time of sexual intercourse and the time that the fertilized egg implants in the uterus. 14 days is a little long, it usually takes five days just for the egg to travel down the fallopian tube.
What two tissues does placenta form?
trophoblasts/chorionic villi and the uterus form the placenta
After fertilization the develops into a seed and the develops into a fruit?
egg and ovule The ovule develops into a seed and the ovary develops into a fruit.
What develops from an embryo?
In plants embryo develops in new seedling and in animals it develops into feotus which later develops into baby
