Nervous System In Depth: Nervous. The nervous system has two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The central system is the primary command center for the body, and is comprised of the brain and spinal cord. The peripheral nervous system consists of a network of nerves that connects the rest of the body to the CNS. The two systems work together to collect information from inside the body and from the environment outside it.

The Nervous System The structures that form the nervous system can be divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The organs of the CNS are the brain (cerebrum, brainstem and cerebellum) and spinal cord.The PNS is made of nerves and neural ganglia. In addition to these organs, the meninges (dura-mater, arachnoid and pia-mater) are also a part of the nervous system, since they cover and protect the encephalon and the spinal cord.ost neurons are located within the brain and the spinal cord (the central nervous system) in places known as neural nuclei. Neural ganglia, or simply ganglia, are structures of the peripheral nervous system located beside the spine or near certain organs, in which neuron cell bodies are also located.

Parts of the Nervous System Parts of the Nervous System. The center of the nervous system is the brain. The brain takes in what your eyes see and ears hear, and if you decide that you want to move around, your brain tells your muscles to do it. Your brain makes your muscles move by sending tiny electrical signals to them through your nerves. Peripheral nervous system (PNS): a part of the nervous system which includes all the nerves outside of the brain and spinal cord. 2  Sympathetic nervous system: The part of your nervous system that unconsciously controls your organs and glands when you're excited or frightened.

Parts of the Nervous System The nervous system is really complicated, but it can be divided into two really general parts. One is the Central Nervous System (or CNS). The CNS consists of your brain and spinal cord. The brain and spinal cord are inside your skull and vertebrae (the vertebrae make up your backbone).

Nervous system Dr. William E. Skaggs, Scholarpedia. The nervous system is the part of an animal's body that coordinates its behavior and transmits signals between different body areas. In vertebrates it consists of two main parts, called the central nervous system (CNS) and the peripheral nervous system (PNS).

- The nervous system consists of two main parts: the central nervous system and the peripheral nervous system: 1  The central nervous system is made up of the brain and spinal cord.he peripheral nervous system is made up of the nerve fibers that branch off from the spinal cord and extend to all parts of the body, including the neck and arms, torso, legs, skeletal muscles and internal organs.

Central Nervous System Function The two main organs of the CNS are the brain and spinal cord. Photo Credit: Credit: Dream Designs/ FreeDigitalPhotos.net. The central nervous system (CNS) is the processing center for the nervous system. It receives information from and sends information to the peripheral nervous system. The two main organs of the CNS are the brain and spinal cord. The brain processes and interprets sensory information sent from the spinal cord. Both the brain and spinal cord are protected by three layers of connective tissue called the meninges.

What are the parts of the nervous system? The brain sends messages through the spinal cord and nerves of the peripheral nervous system to control the movement of the muscles and the function of internal organs.The basic working unit of the nervous system is a cell called a neuron.The human brain contains about 100 billion neurons.he peripheral nervous system is made up of the nerve fibers that branch off from the spinal cord and extend to all parts of the body, including the neck and arms, torso, legs, skeletal muscles and internal organs.

Rare-earth element They are not especially rare, but they tend to occur together in nature and are difficult to separate from one another. However, because of their geochemical properties, rare earth elements are typically dispersed and not often found concentrated as rare earth minerals in economically exploitable ore deposits. The first such mineral discovered was gadolinite, a mineral composed of cerium, yttrium, iron, silicon and other elements. This mineral was extracted from a mine in the village of Ytterby in Sweden; four of the rare earth elements bear names derived from this single location.

Nervous system The nervous system of an animal coordinates the activity of the muscles, monitors the organs, constructs and also stops input from the senses, and initiates actions. The nervous system of vertebrate animals is often divided into the central nervous system (CNS) and the peripheral nervous system (PNS).
