    The Nervous System

    The Nervous System Introduction to the Nervous System

    The nervous system controls bodily function by gathering sensory input, integrating that information internally, and communicating proper motor output.

    LEARNING OBJECTIVES

    Describe the hierarchical structure of the nervous system

    KEY TAKEAWAYS

    Key Points

    The nervous system is the body’s main communication system; it gathers, synthesizes, and uses data from the environment.

    The most basic unit of the nervous system is the neuron, which serves as both a sensor and communicator of internal and external stimuli.

    The nervous system can be broken down into two major parts—the central nervous system and the peripheral nervous system.

    The central nervous system, the main data center of the body, includes the brain and spinal cord.

    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.

    Key Terms

    central nervous system: In vertebrates, the part of the nervous system comprising the brain, brainstem, and spinal cord.peripheral nervous system: The part of the nervous system comprising a large system of nerves that are linked to the brain and spinal cord; this system is divided into the autonomic and somatic nervous systems.neuron: A cell of the nervous system, which conducts nerve impulses; consisting of an axon and several dendrites. Neurons are connected by synapses.innervate: To supply nerves to a tissue.

    The nervous system allows organisms to sense, organize, and react to information in the environment. The basic unit of the nervous system is the neuron. Synapses form between the neurons, allowing them to communicate to other neurons or other systems in the body. The general flow of information is that the peripheral nervous system (PNS) takes in information through sensory neurons, then sends it to the central nervous system (CNS) to be processed. After processing, the CNS “tells” the PNS what to do—what muscles to flex, whether the lungs need more oxygen, which limbs need more blood, any number of biological processes—and the PNS makes it happen through muscle control. The neurons responsible for taking information to the CNS are known as afferent neurons, while the neurons that carry the responses from the CNS to the PNS are known as efferent neurons.

    The human nervous system: The nervous system of the human body, including the brain and spinal cord (central nervous system) and all the nerves of the body (peripheral nervous system).

    The nervous system can be divided into two major parts—the central nervous system (CNS) and the peripheral nervous system (PNS).

    Central Nervous System

    The central nervous system includes the spinal cord and the brain. The brain is the body’s main control center. The main function of the CNS is the integration and processing of sensory information. It synthesizes sensory input to compute an appropriate motor response, or output.

    Peripheral Nervous System

    The peripheral nervous system includes a large system of nerves that are linked to the brain and spinal cord. It is comprised of sensory receptors, which process changes in internal and external stimuli and communicate that information to the CNS. The PNS can be further subdivided into the autonomic nervous system and the somatic nervous system.

    Autonomic Nervous System

    The autonomic nervous system regulates involuntary actions such as internal-organ function and blood-vessel movement. It supplies nerves to (“innervates”) cardiac and smooth muscle tissue. The autonomic nervous system is made of two components, which work in opposition to one another: the sympathetic nervous system, responsible for the body’s “fight-or-flight” response to danger, and the parasympathetic nervous system, which calms the body back down.

    Somatic Nervous System

    The somatic nervous system controls voluntary movements such as those in the skin, bones, joints, and skeletal muscles.

    Both of these systems within the PNS work together with the CNS to regulate bodily function and provide reactions to external stimuli.

    The Central Nervous System (CNS)

    The central nervous system is made up of the brain and spinal cord, which process sensory input and provide instructions to the body.

    LEARNING OBJECTIVES

    Describe the structural elements of the central nervous system

    KEY TAKEAWAYS

    Key Points

    The central nervous system (CNS) and the peripheral nervous system (PNS) comprise the entirety of the body’s nervous system, which regulates and maintains its most basic functions.

    The CNS is the main control center of the body—it takes in sensory information, organizes and synthesizes this input, then provides instructions for motor output to the rest of the body.

    The CNS is made up of the brain and spinal cord.

    The brain is the main data center of the body, consisting of the cerebrum (which regulates higher-level functioning such as thought) and the cerebellum (which maintains coordination).

    The brain stem includes the midbrain, pons, and medulla, and controls lower-level functioning such as respiration and digestion.

    How does the nervous system work?

    The nervous system is made up of all the nerve cells in your body. It takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. The central nervous system (CNS) includes the nerves in the brain and spinal cord. All of the other nerves in the body are part of the peripheral nervous system (PNS).

    How does the nervous system work?

    Created: October 28, 2009; Last Update: August 19, 2016; Next update: 2022.

    The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.

    There are many billions of nerve cells, also called neurons, in the nervous system. The brain alone has about 100 billion neurons in it. Each neuron has a cell body and various extensions. The shorter extensions (called dendrites) act like antennae: they receive signals from, for example, other neurons and pass them on to the cell body. The signals are then passed on via a long extension (the axon), which can be up to a meter long.

    The nervous system has two parts, called the central nervous system and the peripheral nervous system due to their location in the body. The central nervous system (CNS) includes the nerves in the brain and spinal cord. It is safely contained within the skull and vertebral canal of the spine. All of the other nerves in the body are part of the peripheral nervous system (PNS).

    Regardless of where they are in the body, a distinction can also be made between voluntary and involuntary nervous system. The voluntary nervous system (somatic nervous system) controls all the things that we are aware of and can consciously influence, such as moving our arms, legs and other parts of the body.

    The involuntary nervous system (vegetative or autonomic nervous system) regulates the processes in the body that we cannot consciously influence. It is constantly active, regulating things such as breathing, heart beat and metabolic processes. It does this by receiving signals from the brain and passing them on to the body. It can also send signals in the other direction – from the body to the brain – providing your brain with information about how full your bladder is or how quickly your heart is beating, for example. The involuntary nervous system can react quickly to changes, altering processes in the body to adapt. For instance, if your body gets too hot, your involuntary nervous system increases the blood circulation to your skin and makes you sweat more to cool your body down again.

    Both the central and peripheral nervous systems have voluntary and involuntary parts. However, whereas these two parts are closely linked in the central nervous system, they are usually separate in other areas of the body.

    The involuntary nervous system is made up of three parts:

    The sympathetic nervous system

    The parasympathetic nervous system

    The enteric (gastrointestinal) nervous system

    The sympathetic and parasympathetic nervous systems usually do opposite things in the body. The sympathetic nervous system prepares your body for physical and mental activity. It makes your heart beat faster and stronger, opens your airways so you can breathe more easily, and inhibits digestion.

    The parasympathetic nervous system is responsible for bodily functions when we are at rest: it stimulates digestion, activates various metabolic processes and helps us to relax. But the sympathetic and parasympathetic nervous systems do not always work in opposite directions; they sometimes complement each other too.

    The enteric nervous system is a separate nervous system for the bowel, which, to a great extent, autonomously regulates bowel motility in digestion.
