Prenatal Development Lifespan Development

Stages Of Prenatal Development By the 12th week, the fetus has all its body parts including external genitalia. in the following weeks, the fetus will develop hair, nails, teeth and the excretory and digestive systems will continue to develop. at the end of the 12th week, the fetus is about 3 inches long and weighs about 28 grams. Prenatal brain development. prenatal brain development begins in the third gestational week with the differentiation of stem cells, which are capable of producing all the different cells that make up the brain (stiles & jernigan, 2010). the location of these stem cells in the embryo is referred to as the neural plate.

In the following weeks, the fetus will develop hair, nails, teeth and the excretory and digestive systems will continue to develop. the fetus is about 3 inches long and weighs about 28 grams. figure 2.7: fetus. during the 4 th – 6 th months, the eyes become more sensitive to light and hearing develops.

Let’s explore prenatal development. prenatal development is divided into three periods: the germinal period, the embryonic period, and the fetal period. the germinal period begins at conception and continues until the organism is attached to the lining of the uterus, about 14 days. during the germinal period, cells first make copies of them. From 9–12 weeks, the sex organs begin to differentiate. at about 16 weeks, the fetus is approximately 4.5 inches long. fingers and toes are fully developed, and fingerprints are visible. by the time the fetus reaches the sixth month of development (24 weeks), it weighs up to 1.4 pounds.
