GENERAL KNOWLEDGE

Detailed explanation-1: -Almost all organs are completely formed by about 10 weeks after fertilization (which equals 12 weeks of pregnancy). The exceptions are the brain and spinal cord, which continue to form and develop throughout pregnancy. Most malformations (birth defects) occur during the period when organs are forming.

Detailed explanation-2: -The third month of pregnancy is when an embryo becomes a fetus. It’s a period of rapid growth and development. The fetus develops distinct facial features, limbs, organs, bones and muscles. By the end of the 12th week, the fetus has an assigned sex, but it won’t be visible on ultrasound for several more weeks.

Detailed explanation-3: -By the end of the 2nd month of pregnancy, the fetus develops limbs and digits. By the end of 3-4th month, most of the major organ systems are formed, for example, the limbs and external genital organs are well-developed.
