Human Body Nerves Image
Nerves of the body are a part of a very complicated organ system of the human body, known as the nervous system. They basically form a network of signal carriers, that carry signals to and from the brain to various organs. Understanding their working is a little complicated, but here’s an attempt to help you out.
Diagram of the Human Nervous System (Infographic) Find out about the workings of the brain and nerves. The nervous system, essentially the body’s electrical wiring, is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body.
The nerves are the important components of human nervous system. Broadly, the nervous system is divided into two parts; Central Nervous System (CNS): It consists of the brain and the spinal cord.

Spinal Nervous System
(The spinal nerves and the area that they innervate are described in the section The peripheral nervous system: Spinal nerves.) central nervous system: humanThe brain and the spinal cord constitute the central nervous system.Created and produced by QA International.
Nerves – Neural tissue that conducts electrical impulses (messages) from the brain and spinal cord to all other parts of the body; also conveys sensory information from the body to the central nervous system. Nerve root – The initial portion of a spinal nerve as it originates from the spinal cord.
The central nervous system is composed of the spinal cord and the brain , The spinal cord is a cylindrical cord from which the spinal nerves extend , The spinal cord is 40 to 50 cm long and 1 cm to 1.5 cm in diameter .

Picture Of Spine And Nerves
Spinal nerves are the major nerves of the body. A total of 31 pairs of spinal nerves control motor, sensory, and other functions. These nerves are located at the cervical, thoracic, lumbar, sacral, and coccygeal levels.
Spine and Nerves. Many nerves of the peripheral nervous system, which transport signals to and from specific parts of the body, meet the spinal cord at the vertebral column. Other roles for the vertebrae include helping support the body’s weight and providing an anchor for the ribs. The typical adult has 33 total vertebrae,…
The spinal cord does not run through the lumbar spine (lower back). After the spinal cord stops in the lower thoracic spine, the nerve roots from the lumbar and sacral levels come off the bottom of the cord like a “horse’s tail” (named the cauda equina) and exit the spine.

The Nervous System Chart
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands,…
Nervous System. 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.
Structural Divisions of the Nervous System. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 8.2).

Spine And Nerves Illustrations
Spinal nerves are the major nerves of the body. A total of 31 pairs of spinal nerves control motor, sensory, and other functions. These nerves are located at the cervical, thoracic, lumbar, sacral, and coccygeal levels.
Motor messages to the spinal nerves originate in the brain. The motor strip (homunculus) in the brain initiates a command for muscle control. This command is sent to the spine through nerve impulses and then travels through the motor root to the spinal nerve.
These are muscle movement, sensation, and autonomic functions (control of internal organs). Because their function is so well understood, when a particular spinal nerve becomes impaired, the resulting deficit often pinpoints which spinal nerve or nerves are affected. Motor messages to the spinal nerves originate in the brain.

Pictures Of Nervous System
Your Command Central Made up of billions of nerve cells called neurons, your nervous system is what lets you do everything from breathe to walk to dream. It has two main parts: the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system (all the other nerves in your body).
Sympathetic Nervous System. This part of your autonomic system is in charge of your body’s “fight or flight” response. When you come across a threat, your sympathetic nervous system kicks into gear, quickly changing body processes like your breathing and heart rate so that you have extra energy and are ready to face the danger or run away.
Nervous System. 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. Together, these organs are responsible for the control of the body and communication among its parts.

Peripheral Nervous System Pictures
The peripheral nervous system (PNS) is one of the two main parts of the body’s nervous system. The central nervous system (CNS) is comprised of the brain and the spinal cord. The peripheral nervous system branches outside of the central nervous system and is comprised of nerves and neurons that transmit information to and from the brain.
The peripheral nervous system consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves.
This allows the brain and spinal cord to both receive and send information to other areas of the body. In this way, it allows us to react to environmental stimuli. In the peripheral nervous system information is transmitted by bundles of nerve fibers or axons.

What Are The Organs Of The Nervous System
The Main Organs The main organs of the nervous system are, the brain, the spinal cord and the nerves. The brain functions to keep your memory. The spinal cord helps you keep balance. The nerves function for you to be able to feel things.
The anatomy of the nervous system in humans consists of the brain and spinal cord, along with the primary sense organs and all the nerves associated with these organs. The brain and the spinal cord form the central nervous system (CNS). All other neuronal tissue is brought under the umbrella of the peripheral nervous system (PNS).
The central nervous system is made up of the brain, the spinal cord and even the retina, and it is directly responsible for the translation of the messages sent by the peripheral nervous system, which is the network of nerves that run throughout the body.
