In which prenatal assessment procedure is tissue taken from the membrane around the embryo?
The prenatal assessment procedure in which tissue is taken from the membrane around the embryo is called chorionic villus sampling (CVS). This procedure involves extracting chorionic villi, which are tiny projections from the placenta that contain genetic material from the fetus. CVS is typically performed between the 10th and 13th weeks of pregnancy and can help diagnose genetic disorders.
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 hormone is secreted by the developing embryo?
Human chorionic gonadotropin (hCG) is the hormone secreted by the developing embryo after implantation in the uterus. It is detected in the blood and urine and is commonly used as a marker for pregnancy testing.
What does Chorionic villi become?
Chorionic villi develop into the placenta, an organ that provides oxygen and nutrients to the developing fetus and removes waste products. The placenta also plays a crucial role in hormone production to support pregnancy.
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 temporary gland releases chorionic gonadotropin?
Placenta produces Human chorionic gonadotropin hormone.It is tested for pregnancy.
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.
When should Chorionic villus sampling be done?
Chorionic villus sampling is best performed between 10 and 12 weeks of pregnancy
Who should chorionic villus biopsy not be done on?
Chorionic villus biopsy is not recommended for women who have vaginal bleeding or spotting during the pregnancy
Who should Chorionic villus sampling not be done on?
Chorionic villus sampling is not recommended for women who have vaginal bleeding or spotting during the pregnancy
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).
