What develops into the brain and spinal cord in humans?

The ectoderm is also sub-specialized to form the (2) neural ectoderm, which gives rise to the neural tube and neural crest, which subsequently give rise to the brain, spinal cord, and peripheral nerves. The endoderm gives rise to the lining of the gastrointestinal and respiratory systems.

What forms the brain and spine?

Together, the brain and spinal cord form the central nervous system. This complex system is part of everything we do.

Where does the spinal cord develop from?

The spinal cord is made from part of the neural tube during development. There are four stages of the spinal cord that arises from the neural tube: The neural plate, neural fold, neural tube, and the spinal cord. Neural differentiation occurs within the spinal cord portion of the tube.

What are the four steps of nervous system development?

Neuronal Development

  • Embryonic Development: The Beginning.
  • Neuronal Development. Stage 1: Neurogenesis. Stage 2: Cell Migration. Stage 3: Differentiation. Stage 4: Outgrowth.
  • Neuronal Development in Adults.
  • Neuronal Development for Memory and Learning. References.

What is the back of the brain responsible for?

The cerebellum is at the back of the brain, below the cerebrum. It’s a lot smaller than the cerebrum. But it’s a very important part of the brain. It controls balance, movement, and coordination (how your muscles work together).

Which spinal nerves affect which parts of the body?

The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.

What stage does the spinal cord develop?

The spinal cord, and with it the Central Nervous System (CNS) , begin its development in the 3rd week of the embryonic period. At approximal 21 days after fertilization, the ectodermal germ layer is pear shaped, and broder in the cephalic (head) than in the caudal region.

What is the development of the nervous system called?

Early development

In a process called neurulation, the neural folds curve upward and fuse to form the neural tube, which will eventually become the CNS. The neural plate also forms the neural crest, cells of which will later migrate to different parts of the body and become most of the cells in the PNS and ANS.
