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 control system of the nervous system?
The central nervous system includes the spinal cord and the brain. The brain is the body’s main control center. The main function of the CNS is the integration and processing of sensory information.
Which part of the nervous system controls the?
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 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 system controls all the system of the body?
Think of the brain as a central computer that controls all the body’s functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back.
What are the 5 main parts of the 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. Together, these organs are responsible for the control of the body and communication among its parts.

- Efferent neurons. …
What are the three main parts of the 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 are parts of nervous system?
The nervous system is made up of the central nervous system and the peripheral nervous system: The brain and the spinal cord are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.
Which of the following is the main function of the 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.
How does the nervous system control homeostasis?
When a body system leaves a set point and falls outside its normal range, signals are sent through the nervous system which trigger responses to bring the system back into the normal range of functioning. This is the process of homeostasis.
Which part of body is not controlled by nervous system?
The organs that are not controlled by the autonomic nervous system are the skeletal muscles.
Why is the nervous system called the control center of the body?
After the brain has processed the information, impulses are then conducted from the brain and spinal cord to muscles and glands, which is called motor output. … The brain is the body’s “control center.” The CNS has various centers located within it that carry out the sensory, motor and integration of data.
