what are the three functions of the nervous system?
14349
The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.

Functions of the nervous system are sensory input, integration, control of muscles and glands, homeostasis, and mental activity. Nerves carry the signals to the brain. Cells comprising the central nervous system and the peripheral nervous system are classified as neural tissue.

Nervous System. 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.

The nervous system is made up of the brain, spinal cord and nerves. It is the body's communication system that controls much of what your body does. It allows you to do things like walk, speak, swallow, breathe and learn, and controls how your body reacts in an emergency.

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.

The nervous system enables humans to react to their surroundings and to coordinate their behaviour. It comprises millions of neurones and uses electrical impulses to communicate very quickly.

The autonomic nervous system is divided into three parts: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body. It does this by extracting information from the environment using sensory receptors.

First, the basic functions of the nervous system are sensation, integration, and response. Secondly, control of the body can be somatic or autonomic—divisions that are largely defined by the structures that are involved in the response.

The nervous system can be functionally divided into 3 actions: sensation, integration, and response. The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses).

The primary function of the somatic nervous system is to connect the central nervous system to the body's muscles and control voluntary movements and reflex arcs.

['Carrying signals from the brain: The spinal cord receives signals from the brain that control movement and autonomic functions.', 'Carrying information to the brain: The spinal cord nerves also transmit messages to the brain from the body, such as sensations of touch, pressure, and pain.']

Integration. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body. It does this by extracting information from the environment using sensory receptors.
