Here's why:
* Nerve tissue is specialized tissue composed of neurons (nerve cells) and glial cells.
* The brain is the control center of the nervous system. It's made up of billions of neurons that communicate with each other and with the rest of the body. These neurons are responsible for processing information, controlling movement, regulating emotions, and much more.
* Glial cells support and protect neurons, providing them with nutrients and insulation.
Other examples of nerve tissue include:
* Spinal cord: The central communication pathway between the brain and the rest of the body.
* Nerves: Bundles of axons (the long, thin extensions of neurons) that carry signals throughout the body.
* Ganglia: Clusters of neurons that act as relay stations for nerve impulses.
So, while the brain is a prominent example, nerve tissue is found throughout the body, enabling communication and control.
