Directions: Answer using complete sentences! Use the information you have been given to answer questions about: Development of the Brain and Brain Damage
Level#1
The human brain begins developing as early as two weeks into a woman’s pregnancy. It begins as a tube made of nerve cells. By about the fifth week of pregnancy, this tube of cells has become bigger, rounder, and more complex. It eventually turns into a small brain. As the fetus, or unborn baby, develops, the brain continues to grow and develop. The brain is considered fully formed by about the fourth month of pregnancy. Any harmful substances that the mother takes into her body can damage the developing brain of the fetus.
1. What happens as the fetus, or unborn baby develops
2. When is the brain considered to be fully formed?
3. Why is it important for a mother to be careful about what she takes into her body during her pregnancy?

As the fetus, or unborn baby, develops, the brain continues to grow and develop. The brain is considered fully formed by about the fourth month of pregnancy. Any harmful substances that the mother takes into her body can damage the developing brain of the fetus. Because the brain controls so many functions, damage to the brain can cause serious health problems. Brain damage can impair many human functions, such as motor skills, muscle control, speech, and powers of reasoning, learning, and thinking.
1. Why is it important that a mother be careful about what she takes into her body during pregnancy?
2. Why is damage to the brain such a serious problem for a person to have?
3. What problems can brain damage cause a person to experience?

Brain damage can impair many human functions, such as motor skills, muscle control, speech, and powers of reasoning, learning, and thinking. When young people suffer brain damage, it is usually due to accidents. Brain tumors and infectious diseases can also be very damaging or even deadly. Not all tumors are cancerous. Tumors that are cancerous can sometimes be treated with surgery and drugs. Meningitis and chorea are two infectious diseases that attack the brain.
1. Explain why brain damage is such a serious problem for a person and what problems it can cause a person to experience.
2. Explain what can cause brain damage in a young person.
3. Explain what can be very damaging or deadly to the brain and what two infectious diseases are known to attack the brain.
