what are the divisions of the nervous system and their functions?
24480
The anatomical divisions are the central and peripheral nervous systems. The CNS is the brain and spinal cord. The PNS is everything else and includes afferent and efferent branches with further subdivisions for somatic, visceral and autonomic function.

The nervous system has three main functions: To collect sensory input from the body and external environment. To process and interpret the sensory input. To respond appropriately to the sensory input.

Shares. The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system ...

The Human Nervous System: The major organs and nerves of the human nervous system. The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS.

There are two major divisions of the nervous system: the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system is made up of the brain, the spinal cord, and the retina and controls essentially all the functions that keep you alive and allow you to experience life.

Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.

The Autonomic Nervous System (ANS) is divided into two functionally distinct divisions, the Sympathetic and the Parasympathetic Divisions. Each consists of nerves that control the activity of the heart, blood vessels, glands, and other organs containing smooth muscles.

The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).

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.

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.

The two major anatomical divisions of the nervous system. Central nervous system. Consists of the brain an spinal cord. Peripheral nervous system.

The nervous system is made up of the central nervous system and the peripheral nervous system. The central nervous system (CNS) is made up of the brain and spinal cord. The brain controls most body functions, including awareness, movements, sensations, thoughts, speech and memory.

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.
1268886
The somatic nervous system is part of the peripheral nervous system. Major functions of the somatic nervous system include voluntary movement of the muscles and organs and reflex movements. In the process of voluntary movement, sensory neurons carry impulses to the brain and the spinal cord.

The nervous system comprises the central nervous system, consisting of the brain and spinal cord, and the peripheral nervous system, consisting of the cranial, spinal, and peripheral nerves, together with their motor and sensory endings.
