Neural tissue is formed by neuroblasts, which are specialized cells that differentiate into neurons and glial cells.

Here's a breakdown:

* Neuroblasts are precursor cells that originate from the neural tube during embryonic development.

* Neurons are the fundamental units of the nervous system, responsible for transmitting information through electrical and chemical signals.

* Glial cells provide support and protection for neurons, playing crucial roles in maintaining the neural environment, forming myelin sheaths, and contributing to brain function.

So, the process of neural tissue formation involves the differentiation of neuroblasts into neurons and glial cells, which then interact to form the complex network of the nervous system.
