Congenital Disease Associated with the central nervous system

Question 1

What is the first step in the formation of the CNS and what structures form?

Answer 1

The first step in the formation of the central nervous system is the formation of the neural plate, and its folding to give rise to the neural tube. The neural tube will then differentiate into the following structures:

• the brain
• the spinal cord
• the cranial and spinal nerves
• the eyes and other sensory organs
• the neural crest
