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.
Many of your nerves are covered by a protective myelin sheath. Motor nerves transmit messages from your brain to your muscles. They carry messages to your hand muscles to make your hand move. Sensory nerves carry information about pain, pressure, and temperature. They carry messages from your hand to your brain. The main nerves in the hand are the radial nerve, median nerve, and ulnar nerve.
