Source: bing.comThe spinal cord is an essential part of the central nervous system, which plays a vital role in regulating the body’s functions. It is the pathway that sends messages from the brain to the rest of the body, controlling our movements, sensation, and organ function. The development of the spinal cord starts early during prenatal development, and it is a complex process that involves different stages. In this blog post, we will discuss when does baby spinal cord develop, the stages of development, and the importance of proper spinal cord development.

When does baby spinal cord develop?
The development of the spinal cord starts around the third week of pregnancy, shortly after the fertilization of the egg. The neural tube, which eventually becomes the brain and spinal cord, is formed during this period. The neural tube grows and eventually fuses together, forming the spinal cord. By the end of the fourth week of pregnancy, the spinal cord’s basic structure is established, and it starts to differentiate into three primary regions: the cervical, thoracic, and lumbar.
The development of the spinal cord continues throughout the pregnancy, with the spinal cord’s different regions and segments developing in a specific order. The spinal cord’s upper segments, including the cervical and thoracic regions, develop first, followed by the lower segments, including the lumbar and sacral regions. By the end of the third month of pregnancy, the spinal cord’s development is complete, and it is fully functional.
Stages of spinal cord development
Spinal cord development is a complex process that involves different stages. Here are the stages of spinal cord development:
Neural Plate Stage
The neural plate stage is the first stage of spinal cord development, which starts around the third week of pregnancy. During this stage, the neural plate, a flat structure that eventually becomes the brain and spinal cord, forms from the ectoderm, the outermost layer of the embryo.
Neural Fold Stage
During the neural fold stage, the neural plate folds in on itself, forming a groove in the middle. The groove eventually fuses, forming the neural tube, which becomes the brain and spinal cord.
Neurulation
Neurulation is the process of forming the neural tube, which occurs during the neural fold stage. The neural tube eventually becomes the brain and spinal cord, and it starts to differentiate into different regions and segments.
Ganglionic Emminence Stage
The ganglionic eminence stage is the stage where the spinal cord starts to differentiate into different regions and segments, which occurs around the seventh week of pregnancy. The spinal cord’s upper segments, including the cervical and thoracic regions, develop first, followed by the lower segments, including the lumbar and sacral regions.
The importance of proper spinal cord development
Proper spinal cord development is essential for the overall health and well-being of the baby. A healthy spine and spinal cord are necessary for proper movement, sensation, and organ function. Any disruption in spinal cord development can lead to a wide range of problems, including spinal cord defects, paralysis, and other neurological disorders.
The most common spinal cord defect is spina bifida, which occurs when the neural tube does not close properly during early pregnancy. This condition can cause severe physical and neurological problems, including paralysis, bladder and bowel dysfunction, and learning disabilities.
Frequently asked questions
What can affect spinal cord development?
Several factors can affect spinal cord development, including genetics, environmental factors, and maternal health. Some environmental factors, such as exposure to certain chemicals and radiation, can increase the risk of spinal cord defects.
Can spinal cord defects be detected during pregnancy?
Yes, spinal cord defects can be detected during pregnancy through ultrasound and other imaging tests. Early detection and proper medical care can help reduce the risk of complications and improve the baby’s outcome.
What can be done to promote healthy spinal cord development?
Maintaining proper maternal health, including getting regular prenatal care, eating a healthy diet, and avoiding harmful substances, can help promote healthy spinal cord development. Additionally, taking folic acid supplements before and during pregnancy can reduce the risk of spinal cord defects.
What are the symptoms of spinal cord defects?
The symptoms of spinal cord defects depend on the severity and location of the defect. Common symptoms include paralysis, weakness, numbness, bladder and bowel dysfunction, and learning disabilities.
Can spinal cord defects be treated?
Treatment for spinal cord defects depends on the severity and location of the defect. In some cases, surgery can correct the defect or alleviate the symptoms. In other cases, lifelong medical care and rehabilitation may be necessary.
In conclusion, spinal cord development is a complex process that starts early during prenatal development. Proper spinal cord development is essential for the baby’s overall health and well-being, and any disruption in spinal cord development can lead to a wide range of problems. Maintaining proper maternal health and getting regular prenatal care can help promote healthy spinal cord development and reduce the risk of complications.
