Seeing The Development Of The Brain On The Fetus

Seeing The Development Of The Brain On The Fetus – Pregnant women are very enthusiastic and curious to know the growth of their little boy in the womb. In addition to physical growth, the timeline of fetal brain development is very important, not only to know, but also to understand it better.

Brain On The Fetus

Did you know that genes contribute to about 60% of brain development, the environment in the uterus to about 30% and maternal nutrition up to about 10%! Although genes provide a basic blueprint for fetal brain development, the development of sound depends on certain external factors such as nutrition and maternal well-being, avoiding exposure to toxins etc.

how the brain works, what makes it tick always tickle and lure researchers. All the progress and regression in our lives can be easily attributed to the way our brains work, think, sum up, reason, etc. Life begins at conception, and until the eighth week is known as an embryo. From the eighth week onwards until birth, he is known as the fetus. The development of the brain involves the formation of the brain, the nervous system and the spinal cord, and begins at the stage of the embryo itself.

Brain Development Time On Fetus
Stages of Brain Development In Fetus starts from the first week and until week 40. Scroll down and see the stages of brain development that the baby will experience before birth.

  • Week 1-2: Eggs are planted into the uterine wall, and conception is considered to be two weeks old.
  • Week 3: While still an embryo in its definition and formation, the backbone, cardiovascular system and brain begin to form.
  • Week 4: At this stage, the embryo further develops three parts of the brain; the forebrain, the midbrain and the back of the brain, along with the optical stalk.
  • Week 5: As the brain develops, other organs such as the circulatory system begin to function with all four heart chambers. Facial features begin to evolve, with clear vision (via ultrasound) arms and legs, complete with fingers.
  • Week 6: This week looks at the formation of the cerebral hemispheres as well as some wave activity. The neural tube connecting the brain and spinal cord also closes in this duration.
  • Week 7: In this week, the brain grows fast.
  • Week 8: In this week, the head is big enough, compared to other body parts. The development of the back of the brain, responsible for regulating heart rate, respiration and all the related muscular movements also begins now.
  • Week 9: The nervous system is now developing enough to function properly.
  • Week 10: The genitals begin to develop at this stage, determining the sex of the fetus. The development of the brain is also very rapid because the brain makes up 250,000 neurons per minute.
  • Week 11: The spinal cord is clearly defined and the spinal cord begins stretching from the spinal cord.
  • Week 12: The brain enlarges very little compared to the size and shape of its birth, along with the development of buds and vocal cords.
  • Week 13: This week sees the completion of the first trimester. Heart, liver, spleen and many other organs are functioning.
  • Week 14: At this stage, the baby takes a lot of food through the placenta. The fetus also begins to practice breathing – inhaling and exhaling.
  • Week 15: Baby’s body is now expanding rapidly and covered by lanugo; Smooth hair that protects the skin. The sense of hearing is also getting sharper at this stage.
  • Week 16: The baby makes his presence known by pulling and pulling the umbilical cord.
  • Week 17: At this stage, the uterus begins to expand, giving more space to the baby. As bones grow and become hard, protection is needed. The spinal cord is protected by a barrier made from a substance called ‘myelin’.
  • Week 18: The baby develops sensitivity to light and at the same time, the brain develops rapidly.
  • Week 19: The brain becomes capable of forming millions of motor neurons, allowing the baby to thrive and make voluntary muscle movements. The future of the brain develops further into the left and right cerebral hemispheres. The nerve cells needed to process all the senses are also growing rapidly.
  • Week 20: Nerve cells at this stage make complex connections and sensory perceptions with the brain and the rest of the body. This development continues until the age of 5 or 6 years.
  • Week 21: Fetal growth and development are slowing down this week. The organs, especially the heart gets stronger, and the more fat accumulates in the baby’s muscles.
  • Week 22: As the brain perceives complex sensory perceptions, the fetus becomes able to distinguish between different sounds.
  • Week 23: All the nerve cells that had been formed and developed independently, began to form a complete nervous system.
  • Week 24: At this stage, the brain starts to regulate all the functions of the body
