Also, it may be possible to see the first visible sign of the embryo, known as the fetal pole, at this stage. The heart of a fetus is fully developed by the 10th week of pregnancy. Learn more about the development of the heart in weeks 5–10 below.

How hard is pregnancy on the body?

However, it's not until 14 or 15 weeks that you can clearly begin to see the differentiated genitalia.

What week is baby's brain fully developed?

Your baby's brain development is a complex process that continues throughout your pregnancy. At just six weeks, the embryo's brain and nervous system begin to develop, although the complex parts of the brain continue to grow and develop through the end of pregnancy, with development ending around the age of 25.

When does a fetus have a brain?

The fetal brain begins to develop during the third week of gestation. Neural progenitor cells begin to divide and differentiate into neurons and glia, the two cell types that form the basis of the nervous system. By the ninth week, the brain appears as a small, smooth structure.

What do babies do in the womb?

Your unborn baby's first muscle movements were involuntary, but the first voluntary muscle movements occur around week 16.
