What is the functional relationship of the peripheral nervous system to the central nervous system?

The peripheral nervous system’s main job is to send information gathered by the body’s sensory receptors to the CNS as quickly as possible. Once the CNS has understood the information, the PNS will relay the specific orders back out the body.

What is the relationship between CNS and PNS?

If the central nervous system is the command centre of the body, the peripheral nervous system (PNS) represents the front line. The PNS links the CNS to the body’s sense receptors, muscles, and glands.

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 is the relationship between the two parts of the nervous system?

The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

What does the peripheral nervous system do how does it connect the CNS to the rest of the body?

The PNS consists of the nerves and ganglia outside the brain and spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.

What is the main difference between the CNS and PNS?

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.

What is the main difference between the central nervous system and the peripheral nervous system quizlet?

the CNS is the control center, brain and spinal cord. The PNS is nerve fibers that carry information to and from the CNS. White matter is myelinated fibers and is in the inside of the brain and outside of spinal cord. You just studied 85 terms!

What are the 3 functions of the central nervous system?

The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.

What is the main function of CNS?

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 is the main function of nervous system?

The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.

What is nervous system parts and functions?

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.

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).

Which of the following is the best example of the function of the peripheral nervous system?

The best example of the peripheral nervous system is that it connects the central nervous system to the rest of the body. Explanation: The ‘peripheral nervous system’ connects the ‘central nervous system’ to the various organs of the human body and to the limbs and skin.

What does the peripheral nervous system do when scared?

When a person is frightened, for example, sympathetic motor neurons trigger adrenaline release, increase the heartbeat and blood pressure, close off blood vessels to the gut and open them to the skeletal muscles, dilate the pupils, and open the airways.

Which part of the peripheral nervous system is most important in helping you to walk?

Explanation: Somatic peripheral nervous system is most important in helping you to walk. The somatic nervous system also called a voluntary nervous system and it is the part of the motor nervous system in which motor neurons are present that help in the voluntary movements of the organs and the muscles.

What are the two parts of the peripheral nervous system?

The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system. The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities.
