Nervous system development

Nervous system development is the process by which the brain, spinal cord, and nerves form and grow, beginning early in life. It starts with the creation of neural cells (neurons) that migrate to their proper places. These neurons connect through synapses, forming the complex networks responsible for sensation, movement, and thinking. This process involves cell division, movement, and signaling, guided by genetic instructions and environmental factors. Proper development ensures a functional nervous system, supporting learning, responses, and coordination throughout life.
