Detailed explanation-1: -The embryonic stage lasts from about the third week of pregnancy until the eighth week of pregnancy. The blastocyst begins to take on distinct human characteristics. It’s now called an embryo. Structures and organs like the neural tube (which later becomes the brain and spinal cord), head, eyes, mouth and limbs form.
Detailed explanation-2: -Week 5 is the start of the “embryonic period.” This is when all the baby’s major systems and structures develop. The embryo’s cells multiply and start to take on specific functions. This is called differentiation. Blood cells, kidney cells, and nerve cells all develop.
Detailed explanation-3: -The first 8 weeks. The first 2 months are when your body gets ready for the changes that pregnancy brings. It’s also the time when your baby’s brain, heart, bones, blood vessels and organs develop.
