The Nervous System The Nervous System is responsible for all the processes that make human life possible. It’s responsible for thinking, dreaming, holding memories 2 separate systems: 1.Central Nervous System (CNS) 2. Peripheral Nervous System (PNS) CNS: includes the brain and the spinal cord PNS: everything else (nerves)

Interesting Facts The brain has about 100 billion neurons. Spinal Cord: carries impulses 43 cm/17 in women 45 cm/18 in men 31 pairs of nerves

Other facts about Nervous System The most important part of the body is the nervous system, more specific, the brain. The nervous system is responsible for everything we do.
