what is the difference between cns and the peripheral 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 1).

The peripheral nervous system is divided into the somatic nervous system, and the autonomic nervous system. The somatic nervous system is under voluntary control, and transmits signals from the brain to end organs such as muscles.

The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord. These nerves form the communication network between the CNS and the body parts. The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.

These nerves extend from the central nervous system to the outermost areas of the body. The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment.

Structure. The peripheral nervous system is itself classified into two systems: the somatic nervous system and the autonomic nervous system. Each system contains afferent and efferent components. The afferent arm consists of sensory (or afferent) neurons running from receptors for stimuli to the CNS.

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. ... The Central nervous system is made up of the brain and spinal cord and The Peripheral nervous system is made up of the Somatic and the Autonomic nervous systems.

The peripheral nervous system includes all of the neurons that sense and communicate data to the central nervous system. The peripheral nervous system can be further divided into the autonomic system, which regulates involuntary actions, and the somatic system, which controls voluntary actions.

The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment. The nerves that make up the peripheral nervous system are actually the axons or bundles of axons from nerve cells or neurons.

The central nervous system is made up of the spinal cord and brain and is the central processing center for all stimuli. Peripheral nervous tissue consists of nerves made up of nerve cells called neurons. Nerves extend all over the body, from the tips of the fingers to internal organs.

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. The nervous system includes both the Central nervous system and Peripheral nervous system.

What is the Peripheral Nervous System (P.N.S.)? ... It's two major functions are to carry information from the sensory organs and internal organs to the CNS, and to convey information between the CNS and all other parts of the body outside the brain and spinal cord.

- The peripheral nervous system includes the cranial nerves (connected to brain innervate the head), spinal nerves (connected to spinal cord innervates the rest of the body), and ganglia (collections of neuron cell bodies in the PNS). ... Inside the ganglia are the cell bodies of the sensory neurons.

Basic Structures The CNS consists of the brain and spinal cord, while the PNS includes all other nervous system tissue. All sensory receptors, sensory neurons and motor neurons are part of the PNS. ... In the CNS, a group of neurons is called a nucleus.

The nervous system has two major divisions: central and peripheral. But the peripheral nervous system is further subdivided into the somatic and autonomic nervous system, and the autonomic nervous system is also divided into sympathetic and parasympathetic fibers.

Peripheral Nervous System. The peripheral nervous system is divided into two major parts: the somatic nervous system and the autonomic nervous system.

the CNS is the control center, brain and spinal cord. The PNS is nerve fibers that carry information to and from the CNS.

Divisions of the Peripheral Nervous System. The PNS is divided into two major systems, called the autonomic nervous system and the somatic (or sensory-somatic) nervous system. Both systems of the PNS interact with the CNS and include sensory and motor neurons, but they use different circuits of nerves and ganglia.
