The development of the unborn child's nervous system begins at about <u>5 weeks.</u>
<u />
- A developing fetus's central nervous system begins as a straightforward structure termed the "neural groove," which folds into the "neural tube."
- The brain and spinal cord then develop from this. The brain tube should be closed and fused by day 28 following conception.
- Within her embryonic body, the neural plate, an oval-shaped disc of tissue, begins to form.
- Although the intricate elements of the brain continue to grow and develop through the end of pregnancy, development ends around the age of 25, the brain and nervous system of the embryo start to develop at just 5 weeks.
