The main functions of the nervous system

the main functions of the nervous system The peripheral nervous system is divided into two major parts: the somatic nervous system and the autonomic nervous system somatic nervous system the somatic nervous system consists of peripheral nerve fibers that send sensory information to the central nervous system and motor nerve fibers that project to skeletal muscle.

Nervous systems are of two general types, diffuse and centralized in the diffuse type of system, found in lower invertebrates, there is no brain, and neurons are distributed throughout the organism in a netlike patternin the centralized systems of higher invertebrates and vertebrates, a portion of the nervous system has a dominant role in coordinating information and directing responses. The main divisions of the peripheral nervous system are: the autonomic nervous system — which controls the automatic functions of the body: the heart, smooth muscle (organs) and glands it is divided into the “fight-or-flight” system and the “resting and digesting system. The central nervous system is basically the body's command center it gathers information from stimuli all around the body it is the central nervous system's objective to respond to that stimuli, such as pulling a hand away when it touches a hot stove. The central nervous system cns is responsible for integrating sensory information and responding accordingly it consists of two main components: the spinal cord serves as a conduit for signals between the brain and the rest of the body.

The nervous system has 3 main functions: sensory, integration, and motor sensory the sensory function of the nervous system involves collecting information from sensory receptors that monitor the body’s internal and external conditions. The autonomic nervous system has two divisions: the sympathetic and parasympathetic nervous systems the sympathetic part of the autonomic system (or the thoracolumbar division) prepares the body for emergency situations, also known as fight-or-flight reactions. The autonomic nervous system (ans, or visceral nervous system, or involuntary nervous system) is the part of the peripheral nervous system that acts as a control system, functioning largely below the level of consciousness and controlling visceral functions. The central nervous system is made up of the brain and spinal cord it gathers information from all over the body and coordinates activity we explore the types of cells involved, the regions of.

The functions of nervous system listed in this article helps in understanding the role of the central nervous system, peripheral nervous system and autonomous nervous system in the functioning of the body. The nervous system has three basic functions: sensory neurons receive information from the sensory receptors, interneurons transfer and interpret impulses, and motor neurons send appropriate impulses/instructions to the muscles and glandsif i had to give a main function it would be to control nerves. The functions that i just described are all controlled by the somatic nervous system, which is the part of the nervous system that voluntarily responds to external stimuli all of the different.

Components of the central nervous system this page summarises basic information about the main parts of the central nervous system, sometimes called the cns. The nervous system is the main controlling and communicating system of the body every thing we do, feel and think consciously or unconsciously is directed by the nervous system. Functional divisions of the nervous system the nervous system can also be divided on the basis of its functions, but anatomical divisions and functional divisions are different the cns and the pns both contribute to the same functions, but those functions can be attributed to different regions of the brain (such as the cerebral cortex or the. What is the nervous system the nervous system is a control system of the body and is a bit like a computer the brain is similar to the software and is responsible for making decisions and the nerves are like the hardware or wiring that communicates those decisions with the rest of the body. The nervous system is formed of two parts that are integrally linked with each other the brain and the nervous system has multiple functions that are vital for normal functioning of the body a.

Overview of the entire nervous system [] the nervous system has three main functions: sensory input, integration of data and motor output sensory input is when the body gathers information or data, by way of neurons, glia and synapses. Chapter 23 nervous system study play functions of the nervous system are emotional responsiveness there are 2 basic divisions of the nervous system central and peripheral nervous system central nervous system (cns) functions cns major components are brain, spinal cord, meninges, cerebrospinal fluid all of these are surrounded. Parts of the nervous system, the system of the body that oversees the function of all other systems, include its main organ, the brain its vessels, the spinal cord and peripheral nerves and its cells, known as neurons, which transmit the electrical signals that are nerve impulses. The nervous system is a complex, highly coordinated network of tissues that communicate via electro chemical signals it is responsible for receiving and processing information in the body and is divided into two main branches: the central nervous system and the peripheral 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 nervous system involves the central nervous system (cns) and the peripheral nervous system (pns) cns involves brain and spinal cord, while the pns involves the peripheral sensory and motor nervesall parts are important in their own functions but the brain and spinal cord are more important on a survival and continuity of life basis.

In this lesson we'll learn the definition of 'autonomic nervous system' the lesson explores the system's function and gives an overview of the divisions that comprise the system. The first major function of the nervous system is sensation—receiving information about the environment to gain input about what is happening outside the body (or, sometimes, within the body. It has two systems, the sympathetic nervous system and the parasympathetic system the autonomic nervous system controls muscles in the heart, the smooth muscle of the intestine, bladder, and uterus the sympathetic nervous system is involved in the fight or running away response.
