Are nerves the same as neurons: a bundle of a bunch of different neurons, nerves can sometimes be seen with the naked eye, neurons are too small. Gives you enough energy to survive to save yourself. Rest and digest systems shut down to give energy to other places so you can survive. Dry mouth when in panic because glands are slowed down. Bringing you back to normal level after fright or flight: neurons and neurotransmitters. Carry sensory information to neurons in the brain. Others carry the brain s output to motor neurons to activate muscles and glands. Network of 100 trillion connections amongst neurons. Negative electrical charge of about -70 millivolts.
