Nervous system explained simply

Together the nervous system helps different parts of our body communicate and allows our brain to control what is going on. Sensory neurons respond to external stimuli that affect the sensory organ cells.

The nervous system is the bodys main communication system.

Nervous system explained simply. The nervous system is a body system which sends signals around the body. It lets animals respond to what is around them. The central nervous system is the brain the spinal cord and nerves.

It is present in almost all animals. It is there to process the input from the senses and to to coordinate movement. The nervous system is made up of neurons.

A nervous system can be defined as an organized group of cells called neurons specialized for the conduction of an impulsean excited statefrom a sensory receptor through a nerve network to an effector the site at which the response occurs. Following are the two common ways to divide up the nervous system. The central nervous system CNS includes the brain and spinal cord and the peripheral nervous.

The somatic nervous system regulates the movement of skeletal muscles and the. The human nervous system consists of. The central nervous system CNS the brain and spinal cord the peripheral nervous system nerve cells that carry information to or from the CNS.

The nervous system allows us to react to our surroundings very quickly and to coordinate our behavior. It comprises millions of neurones and electrical impulses pass along them very quickly. Definition The nervous system maintains internal order within the body by coordinating the activities of muscles and organs receives input from sense organs trigger reactions generating learning and understanding and providing protection from danger.

This is primarily conducted through electrochemical signaling between nerves and other cells. All nervous systems in all animal species have four basic types of functional cells. These neurons tell the rest of the brain about the external and internal environment.

Motor and other output neurons. Motor neurons contract muscles and mediate behavior and other output. 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 is the highway along which your brain sends and receives information about what is happening in the body and around it. This highway is made up of billions of nerve cells or neurons say new-rons which join together to make nerves. A nerve is a fibre that sends impulses through the body.

The nervous system is made up of the brain the spinal cord and a large network of nerves that covers all parts of the body. Together the nervous system helps different parts of our body communicate and allows our brain to control what is going on. Without the nervous system our brain would be mush.

Neuron can be considered as the basic unit of the nervous system which processes and transmits information by means of electrochemical signals. Sensory neurons respond to external stimuli that affect the sensory organ cells. Motor neurons on receiving signals from the central nervous system bring about responses at the target organs.

Your nervous system is a wild and wonderful network of nerves that act in different key functions to keep your body moving responding sensing and more. This article is going to examine the. The nervous system is the bodys 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 parasympathetic nervous system is part of the autonomic nervous system.

It does the opposite things of the sympathetic nervous system the other part of the autonomic nervous system. This way the parasympathetic and sympathetic nervous systems balance each others effects. The sympathetic nervous system helps a person fight or flight when they are in danger.

When the danger is gone the parasympathetic nervous system lets the person rest and digest feed and breed. The nervous system is defined by the presence of a special type of cellthe neuron sometimes called neurone or nerve cell. Neurons can be distinguished from other cells in a number of ways but their most fundamental property is that they communicate with other cells via synapses which are membrane-to-membrane junctions containing molecular machinery that allows rapid transmission of.

Definition The central nervous system CNS consists of the brain and spinal cord. This body system is responsible for integrating and coordinating the activities of the entire body. Through these physical structures thought emotion and sensation are experienced and body movements are coordinated.

The biological approach believes us to be as a consequence of our genetics and physiology. It is the only approach in psychology that examines thoughts feelings and behaviors from a biological and thus physical point of view. Therefore all that is psychological is first physiological.
