I think you mean the 'Autonomic' nervous system. It is responsible for regulating internal organs, among other things.
The peripheral nervous system is made up of the sensory (afferent) and motor (efferent) divisions. The motor division is furthermore split into the somatic and autonomic nervous systems. Lastly, the autonomic nervous system is split into the sympathetic (fight or flight) and parasympathetic (rest and digest) nervous systems.
The autonomic nervous system is always on automatic. You don't have to think about it. When it needs to speed up, it speeds up. when it needs to slow down, it slows down. It is all automatic.
neurons
The spinal cord and the brain make up part of the nervous system called the central nervous system. The rest of the system is made up of the peripheral nervous system.
The nervous system is named that way because it is made up of mostly nerves.
brain and spinal cord :)
neuron
The neuron is the nervous cell that makes up about 90 percent of the nervous system. Neurons are the basic building blocks of the nervous system and are responsible for transmitting electrical and chemical signals throughout the body.
Nervous tissue is made up of different cells working together to perform a given function -- in this case, to carry messages from one part of the body to another. Different nervous tissues working together make up nervous system organs, such as nerves, the spinal cord, or the brain. These organs work together in the nervous system, a collection of organs performing a body function. So, in sum, the difference between nervous tissue and the nervous system is one of size and scope: nervous tissue makes up nervous organs, which make up the nervous system.

I'm unable to display pictures or diagrams. However, 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. It is divided into the central nervous system (including the brain and spinal cord) and the peripheral nervous system (consisting of nerves outside the central nervous system).
neuron. Neurons are specialized cells that process and transmit information through electrical and chemical signals in the nervous system. They have a unique structure that allows them to efficiently communicate with other neurons, facilitating the functioning of the nervous system.
