The [[Developmental Biology - Neurogenesis - Anatomy & Physiology|nervous system]] develops from ectoderm in the anterior part of the embryo, beginning with the formation of the neural plate. Some of the ectoderm will also develop into the epidermis in response to signalling factors from elsewhere in the embryo; formation of the neural ectoderm is the default pathway.

The neural plate develops into the neural tube, which is the precursor to the brain and spinal chord.
