Nerves They are like enclosed cables that a made up of Axons that transmit impulses to the body. (Nerve Fibers)

2 Main systems PNS:Somatic and Autonomic CNS:The Brain and Spinal Cord

Nerve Cell The Nerve cell is electrically excitable cell that process and transmit information through chemical signals they have specialized connections with other cells the core components are the brain and spinal cord.

Interesting Facts 1.An adults Brain is 3 times as heavy as a newborn babies 2.A male Brain is 100 grams more than a female 3.Nerve cells are able to transmit impulses at the speed of 100 meters per second
