The end result is the simplest form of etching. There are more complicated ways to create more intricate etchings by using a number of different plates and colors. There is also a process to add different tones to the image that involves adding resin dust to the plate and heating it.
Nerves carry electrochemical signals to and from different areas of the nervous system as well as between the nervous system and other tissues and organs. Nerves are divided into four classes: Cranial nerves connect your sense organs (eyes, ears, nose, mouth) to your brain.
The nervous system is made up of the brain, the spinal cord, and a large network of nerves that covers all parts of the body. Together the nervous system helps different parts of our body communicate and allows our brain to control what is going on.he Nervous System. 1  Motor nerves-Motor nerves allow the brain to control our muscles. 2  Sensory nerves-The second type of nerves are called sensory nerves. 3  Autonomic nervous system-This set of nerves works automatically. 4  Somatic nervous system-These are the nerves that we actively control, like jumping with our legs or moving our arms.
