Nervous tissue helps the body communicate in a few important ways:

1. Neurons:

   • There are about 86 billion neurons in our brains.
   • They send signals quickly, reaching speeds of up to 120 meters per second.

2. Glial Cells:

   • Glial cells make up around 90% of the brain's cells.
   • They support and protect neurons, keeping everything balanced.
   • They also provide insulation, like a protective layer.

3. Synapses:

   • The brain has over 100 trillion synapses.
   • These tiny connections help with the fast sharing of messages between neurons.

By working together, these parts of nervous tissue keep our bodies and minds in touch and functioning smoothly.
