Nervous and Endocrine Systems: Impulses

The video tutorial explains the concept of networks, comparing communication networks to the body's network of nerve cells. It details how nerve impulses travel through neurons, highlighting their speed of up to 120 meters per second. The tutorial also describes how impulses jump across neuron gaps with the help of chemical signals, providing a simplified view of this complex process.

What happens when a nerve impulse reaches a gap between neurons?

Explain the significance of chemical signals in the transmission of nerve impulses.
