Embryology
Embryology is a branch of biology. It involves the study of the embryo from conception until the point at which the zygote becomes a fetus.

Embryo problems refer to issues that can arise during the development of an embryo, such as genetic abnormalities, improper implantation in the uterus, or failure to develop properly. These problems can lead to pregnancy complications or miscarriage. It is important to address any identified embryo problems early on to improve the chances of a successful pregnancy.
Where does cartilage occur in an embryo?
In an embryo, cartilage primarily occurs in several key areas, including the developing skeleton, where it serves as a precursor to bone formation. It is found in structures such as the trachea, bronchi, and the nasal passages, providing support and flexibility. Additionally, cartilage plays a crucial role in the formation of joints and serves as a template for the growth of long bones through endochondral ossification.
What marks the beginning of a germ layer development an embryo?
Gastrulation is first step towards germ layer development .
What useful substance can cross the placenta?
Some examples of useful substnces that can cross the plancenta are:
- oxygen, carbon dioxide
- nutrients
- water
- sodium, potassium, chloride, calcium, phosphorus
- waste products (urea, uric acid, bilirubin)
- foetal and maternal red blood cells
- IgG (immunoglobin-G which provides innate immunity to the baby)
- α-fetoproteins
Is a zygote a two-celled embryo?
No.
The term zygote refers to a much broader period at the earliest stages of an organism's development, from the first fusion of sperm and egg to (form a single celled zygote) through many cell divisions (producing a multi-celled zygote) which matures into a blastocyst. So, zygotes can be one celled, two celled, or many celled.
How does the way that the plant embryo gets its food compare with that of the seedling?
i dont know if its righ orwrong
What on the inner lining of the fallopian tube aids in moving a developing embryo?
The uterine tube is called the fallopian tube and the lining is made up of tiny hairlike, fingers called fimbria. The fimbria move the developing embryo along the fallopian tube to the uterus where it will embed itself. Here it will grow and develop until it is ready to be born in about 9-10 months..
What are the positive and negatives of embryo screening?
Positive: Screening can identify embryos that will develop severe genetic diseases, thus allowing doctors and parents to choose a course of treatment or to terminate the pregnancy.
Negative: The power to screen embryos may result in people screening for relatively trivial things or in extreme cases, eugenic selection of only embryos possessed of specific traits.

Hatching time in ducks depends upon external temperature of the region , as in tropical areas it id 21 days but in Siberia Russia it nearly sixty days .
Which foetal membrane takes part in the formation of placenta?
placenta is a complex structure formed by the process of trophoblastic cells (chorionicfondosum)and part of uterine endometrium called decidua basalis
An embryo develops into a fetus as it continues to grow and mature during pregnancy. The embryo goes through various stages of development, including the formation of organs and body structures, before eventually becoming a fully formed baby at birth.
