An Introduction to Your Nervous System

Scroll down to explore a learning path based on this topic.
Playlist Description

Your nervous system is the sum of many parts. At the center of it all sits your brain, a powerhouse containing billions of nerve cells that fire off complex electrical messages to keep your body safe and healthy as best they can. Your spinal cord runs the length of your back, and connects your peripheral nervous system—the collections of nerve cells around your body—to your brain, ensuring that your entire nervous network is hooked up to the grid.

It’s incredibly important, and incredibly complex. Without a functioning nervous system, you would struggle to do most things—which is why injuries to the spinal cord or brain can be so serious. From the photoreceptors in your eyes, to the neurons in your prefrontal cortex, every day your nervous system does everything it can to help you survive and thrive.

The Anatomy of the Central Nervous System The nervous system is a complex network of nerve cells and nerve fibers spread throughout the body. Its function is to interpret, store, and respond to information received from inside and outside. The central nervous system or CNS, consists of the brain and spinal cord and is responsible for processing information gathered from the rest of the nerves and transmitting instructions to the body. Messages passing to and from the CNS are carried by the nerves of the peripheral nervous system. This system includes twelve pairs of cranial nerves and thirty-one pairs of spinal nerves. The cranial nerves and the spinal nerves control voluntary movements and sensations. The autonomic nervous system, consisting of sympathetic and parasympathetic nerve fibers, controls such involuntary body functions as the heartbeat.

Wherever you go, whatever you do, the world stirs your senses. It is there in the sparkle of fireworks, the flavor of watermelon, the crack of a baseball bat and the scent of summer rain. Sensations like these may seem to come to you automatically. But you only perceive them thanks to an intricate chain reaction of signals inside your brain. The exhibition, Brain: The Inside Story, which is on view at the American Museum of Natural History from Saturday, November 20, until August 14, 2011, brings visitors up to date on the latest in neuroscience, highlighting the brain's surprising ability to rewire itself in response to experience, disability, or trauma, and showcases new technologies that researchers use to study the brain and treat conditions such as Alzheimer's and Parkinson's.
