What are the three types of villi?
The three types of villi are: Intestinal villi-microscopic finger like projections on the inner surface of the ileum. Chorionic villi-villi on the outermost membrane of the foetus. Arachnoid villi-villi on the arachnoid membrane of the brain.
What is A process where a long thin tube is used to withdraw fetal cells from the fetal side of the placenta is?
The process you are referring to is called chorionic villus sampling (CVS). It involves using a long thin tube to obtain a small sample of cells from the chorionic villi on the fetal side of the placenta for genetic testing.
What placental structure has villi?
The chorionic villi, which are finger-like projections on the surface of the chorion (part of the fetal membrane), contain blood vessels that allow for the exchange of nutrients and waste between the mother and the fetus.
What is the inner wall of the villi line?
The small intestine is lined with microscopic fingerlike strutcures called villi which increase the surface area of the small intestine fo absorption. The spaces between villi are like a sieve that absorb the food particles into the bloodstream. There are three types of villi. Intestinal Villi which lines the intestines, Chorionic Villi which is on the outer most membrane of a fetus and Arachnoid Villi which is on the arachnoid membrane of the brain.
What information besides chromosome number can amniocentesis and chorionic villi sampling reveal?
Amniocentesis and chorionic villi sampling (CVS) can provide information about genetic disorders, such as cystic fibrosis, Down syndrome, and spina bifida, by analyzing fetal DNA. They can also reveal the sex of the fetus and assess certain biochemical markers associated with genetic conditions. Additionally, these procedures can identify chromosomal abnormalities, such as translocations or deletions, beyond just the overall chromosome count.
At what week of pregnancy can a chorionic villi sampling be performed?
A chorionic villi sampling can be performed as early as week 10 of the pregnancy.
Does chorionic villi sampling applies in the Philippines?
only on a Tuesday
What advantage does chorionic villi sampling have over amniocentesis?
yes
What structures form the placenta?
Chorionic villi & Decidua Basalis
What are the two methods of prenatal diagnosis?
Amniocentesis and chorionic villi sampling.
What is the purpose of a chorionic villi sampling?
The tissue can be tested for genetic defects.
What structures ultimately forms the placenta?
Chorionic villi & Decidua Basalis

What does chorionic villus sampling involve?
Chorionic villus sampling involves the removal of a small amount of tissue directly from the chorionic villi (minute vascular projections of the fetal chorion that combine with maternal uterine tissue to form the placenta).
How soon in the pregnancy is chorionic villi sampling performed?
The chorionic villus sampling is performed by 10 weeks of gestation. The pregnancy can be safely terminated by this time, if necessary. That is the advantage of the procedure.
What is the placental barrier made up of?
Chorionic Villi with Fetal capillaries Intervillous Spaces Decidua basalis with maternal capillaries
