At what stage of development does a fetus develop its nervous system?

The nervous system of a fetus begins to develop during the first trimester of pregnancy.


At what stage of development does a fetus develop a nervous system?

A fetus develops a nervous system during the embryonic stage of development, which occurs around the 3rd to 8th week of pregnancy.


What is the first organ formed in the fetus?

The heart is the first organ to develop in a fetus. Together, blood and the circulatory system, that is powered by the heart, form the first organ system.


What is the first organ to develop in the embryo?

The first organ to develop in the embryo is the heart. In a fetus, there is a brain, but it isn't fully developed and can't understand signals from the nervous system. Therefore the first functional organ would be the heart. But the first thing to start developing in a fetus is the nervous system. ( no that isn't an organ )

How does toxoplasmosis affect a baby infected early in pregnancy?

If a fetus becomes infected early in pregnancy, the disease can cause the fetus to spontaneously abort, be stillborn. If full-term, the infant may die in infancy or suffer from central nervous system lesions.


Which part grown first in baby?

In a developing fetus, the brain and spinal cord, which are part of the central nervous system, are among the first structures to form. This process, known as neurulation, begins shortly after conception and is crucial for the development of the nervous system. The heart also starts to develop early, becoming functional by the end of the first trimester. Overall, these early developments lay the foundation for the growth of other organs and systems in the body.


Why is the respiratory system less important to a developing fetus than the nervous system?

The respiratory system is less critical to a developing fetus because oxygen and carbon dioxide exchange occurs through the placenta, not the lungs. The fetus receives oxygen directly from the mother's blood, making the lungs non-essential until birth. In contrast, the nervous system is vital for developing critical functions, such as movement, reflexes, and overall brain development, which are essential for survival after birth. Thus, while both systems are important, the nervous system plays a more immediate role in the fetus's development.
