The Nervous System is a complex, highly coordinated network of tissues thatcommunicate via electro chemical signals. It is responsible for receiving and processing
information in the body and is divided into two main branches: the central nervous
system and the peripheral nervous system.
The Central Nervous System
The Central Nervous System receives and processes information from the senses. The
brain and the spinal cord make up the central nervous system. Both organs lie in a fluid
called the Cerebrospinal Fluid, which cushions and nourishes the brain. The
Blood-Brain Barrier protects the cerebrospinal fluid by blocking many drugs and toxins.
This barrier is a membrane that lets some substances from the blood into the brain but
keeps out others.
The Spinal Cord connects the brain to the rest of the body. It runs from the brain down
to the small of the back and is responsible for Spinal Reflexes, which are automatic
behaviors that require no input from the brain. The spinal cord also sends messages
from the brain to the other parts of the body and from those parts back to the brain.
