Nervous system

It may seem as if your brain is always on the go and it is the brain not only controls what you think and feel, how you learn and remember, and the way you move and talk, but also many things you're less aware of — such as the beating of your heart, the digestion of your food, and yes, even the amount of stress you feel. The brain controls everything we do, and is often likened to the central computer within a vast, complicated communication network, working at lightning speed. Fibers called nerves carry important messages back and forth between your body and your brainthat network -- your nervous system -- has two parts: your brain and spinal cord make up your central.

nervous system Nervous systems are of two general types, diffuse and centralized in the diffuse type of system, found in lower invertebrates, there is no brain, and neurons are distributed throughout the organism in a netlike patternin the centralized systems of higher invertebrates and vertebrates, a portion of the nervous system has a dominant role in coordinating information and directing responses.

The human nervous system – interact with diagrams and descriptions of the nervous system anatomy of the human body, everything from the brain to nerve endings.

The nervous system is made up of all the nerve cells in your body it is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled.

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.

Nervous system, organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors through a network to the site at which a response occurs nervous system: movement of nerve impulsesthe movement of impulses through the nerve cell, involving both chemical and. The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.
