What are the three 3 main parts of the nervous system?
The human nervous system is made up of three basic parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system. Without a doubt, it is the most complex part of the human body, a masterpiece of nature.
What are the major 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 are the functions of central nervous system?
Most systems and organs of the body control just one function, but the central nervous system does many jobs at the same time. It controls all voluntary movement, such as speech and walking, and involuntary movements, such as blinking and breathing. It is also the core of our thoughts, perceptions, and emotions.
What is the function of the PNS and CNS?
The primary role of the PNS is to connect the CNS to the organs, limbs, and skin. These nerves extend from the central nervous system to the outermost areas of the body.
What are the main functions of the nervous system?
Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).
What are the functions of the nervous system?
The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
What is the main function of the central nervous system?
What does the central and peripheral nervous system do?
These nerves extend from the central nervous system to the outermost areas of the body. The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment.
What are the 4 main functions of the nervous system?
The four main functions of the nervous system are:
- Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature.
- Programming of spinal cord reflexes. An example of this is the stretch reflex.
- Memory and learning.
- Voluntary control of movement.
What is the function of the ganglia?
Ganglia are clusters of nerve cell bodies found throughout the body. They are part of the peripheral nervous system and carry nerve signals to and from the central nervous system.
What is function of peripheral nervous system?
The PNS has three basic functions: (1) conveying motor commands to all voluntary striated muscles in the body; (2) carrying sensory information about the external world and the body to the brain and spinal cord (except visual information: the optic nerves, which convey information from the retina to the brain, are in …
What are the three functions of the nervous system quizlet?
Terms in this set (6) The three general functions of the nervous system—receiving information, deciding what to do, and acting on those decisions—are termed sensory, integrative, and motor.

What are the 4 major functions of the nervous system?
What is the function of the somatic nervous system?
The somatic nervous system is a component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles.
What are the main functions of the central nervous system?
What are three functions of the nervous system quizlet?
What is Postganglionic and Preganglionic?
The main difference between preganglionic and postganglionic neurons is that preganglionic neurons are the neurons that arise from the central nervous system and supply the ganglia whereas postganglionic neurons are the neurons that arise from the ganglia and supply the tissues.
What is the function of spinal nerves?
Your spinal nerves send electrical signals between your brain, spinal cord and the rest of your body. These electrical nerve signals help you feel sensations (sensory nerve) and move your body (motor nerves).
