Human nervous system, system that conducts stimuli from sensory receptors to the brain and spinal cord and conducts impulses back to other parts of the body. As with other higher vertebrates, the human nervous system has two main parts: the central nervous system (the brain and spinal cord) and…

(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 .

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).

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.

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.

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.
