What happens to an embryo during the first 2 months of pregnancy?

Answer 1

The embryonic period is the first eight weeks of development of the conceptus, beginning with fertilization. During this period, the embryo undergoes an amazing transformation from a single cell to a recognizably human embryo. In the mid-twentieth century, George Streeter devised a commonly used embryo classification system by dividing the embryonic period into 23 stages. The embryonic period is followed by the fetal period, which encompasses the remainder of theprenatal development.

Answer 2

The germinal period is the two week period after the sperm and the egg unite. During this time:

-the zygote (fertilized egg) is created

-the zygote rapidly divides and moves down the fallopian tube

-the zygote is implanted on the uterine wall

-there is rapid cell division.

-the blastocyst (a hollow structure containing cells) separates into three layers. The outer layer (ectoderm), which later forms the skin, hair, salivary glands, nervous tissue, placenta etc, the middle layer (mesoderm) which forms all the bones, blood, teeth, connective tissues, muscles, etc, and the inner layer (endoderm) which forms the majority of the internal organs such as stomach, liver, heart, etc.

Answer 3

during the first two months of developing the embryo is about 2.5 cm long and is biginning to develop recongnizable features
