What Week Does A Baby Develop A Nervous System?

As a new mother, it is essential to understand the development stages of your baby. One of the significant developmental milestones is the development of the nervous system. The nervous system is the control center of the body, and it controls everything from breathing to movement. But when does a baby develop a nervous system? In this article, we will discuss the week when a baby develops a nervous system.

What is the Nervous System?

The nervous system is the body’s communication network. It is made up of two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS is made up of nerves that run throughout the body.

The nervous system is responsible for the control and coordination of all body functions. It regulates breathing, heartbeat, and digestion, as well as complex functions such as learning, memory, and emotions.

When Does the Baby Develop the Nervous System?

The development of the nervous system begins in the early stages of pregnancy. By the end of the third week of pregnancy, the neural plate begins to form. The neural plate is a flat structure that eventually gives rise to the brain and spinal cord.

By the end of the fourth week, the neural plate has folded over to form the neural tube. The neural tube is a hollow structure that eventually becomes the brain and spinal cord.

By the end of the fifth week, the neural tube has closed at the top and bottom, and the brain and spinal cord are beginning to take shape. At this stage, the brain is divided into three parts: the forebrain, midbrain, and hindbrain.

By the end of the eighth week, the brain and spinal cord are fully formed, and the nervous system is beginning to function. At this stage, the fetus is about the size of a grape and weighs about one gram.

What Happens After the Nervous System Develops?

After the nervous system develops, it continues to grow and mature throughout pregnancy and after birth. By the end of the first trimester, the fetus can move its arms and legs, and its fingers and toes are fully formed.

By the end of the second trimester, the fetus can hear and respond to sounds, and its eyes can open and close. The brain is also developing rapidly at this stage, and the fetus can think and feel emotions.

By the end of the third trimester, the fetus is fully developed and ready for birth. The nervous system is functioning correctly, and the fetus can breathe, swallow, and suckle.

What Can Affect the Development of the Nervous System?

Several factors can affect the development of the nervous system. These include genetics, environmental factors, and maternal health. Exposure to toxins such as alcohol, drugs, and certain chemicals can also affect the development of the nervous system.
