Question: What is the basic function of the central nervous system?

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.

What is the function of the central nervous system?

The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.

What are the three main functions of the central nervous system?

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.

The main functions of the central nervous system is to PROCESS information received through sensory systems and other parts of the body and to activate appropriate actions to the external/internal stimuli.

What is the function of CNS and PNS?

The CNS is the brain and spinal cord. The PNS is everything else. Functionally, the nervous system can be divided into those regions that are responsible for sensation, those that are responsible for integration, and those that are responsible for generating responses.

What happens if the central nervous system is damaged?

You may experience the sudden onset of one or more symptoms, such as: Numbness, tingling, weakness, or inability to move a part or all of one side of the body (paralysis). Dimness, blurring, double vision, or loss of vision in one or both eyes. Loss of speech, trouble talking, or trouble understanding speech.

What is nervous system and its function?

The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).

What is an example of the central nervous system?

For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. … 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.

What are the three main functions of a nervous system quizlet?

Terms in this set (3)

  • sensory input. when sensory receptors monitor changes that occur both inside and outside of the body.
  • integration. when sensory information is interpreted and the appropriate response is taken.
  • motor output. response that is performed by effectors- muscles or glands.

What is the main difference between the CNS and PNS?

The CNS consists of the brain and spinal cord, while the PNS includes all other nervous system tissue. All sensory receptors, sensory neurons and motor neurons are part of the PNS.
