Main Parts Of The Central Nervous System – Understand the nervous system. Learn about the central and peripheral nervous system, somatic and autonomic, sympathetic and parasympathetic nervous systems. Updated: 11/21/2023
The three main parts of the nervous system are the brain, the spinal cord and the nerves. The brain is the main processing center of the nervous system. The spinal cord acts as a highway that sends messages between the mind and body. Nerves are extensions of neurons that travel throughout the body and send messages.

Main Parts Of The Central Nervous System
The nervous system is a collection of cells, organs and tissues that control thoughts, feelings and actions. The nervous system uses electrochemical communication to send messages through the body.

What is the nervous system? The nervous system is a collection of cells, tissues and organs in the body that facilitate electrochemical communication throughout the body. The function of the nervous system is to allow communication around the body and to help the body maintain homeostasis, or a state of balance. The nervous system is made up of specialized cells called neurons that can send electrochemical signals. Neurons send messages between the mind and body and allow the control of thoughts, feelings and actions.
There are two main parts of the nervous system: the central nervous system and the peripheral nervous system. Both of these have different parts and functions in the body.
The central nervous system is important for processing information and making decisions. The parts of the central nervous system include the brain and the spinal cord.
The mind is the most important part of the body. All sensory information about the internal and external environment is brought to the brain, where it is processed. The brain then sends signals to cause the appropriate response in the body. The brain is made up of three main parts: the cerebrum, the cerebellum and the brainstem.

The brainstem is the central part of the brain and is responsible for important functions related to homeostasis, such as breathing and heart rate. The cerebellum is involved in fine motor coordination, motor learning, and more. The cerebrum is the main part of the brain. It is divided into sections called lobes, all of which have different functions. For example, the occipital lobe deals with visual information, while the frontal lobe controls our executive functions, emotional regulation, pleasure, speech, and more.
The spine is like the highway of the body. It carries information from the body to the mind and from the mind to the body. The spinal cord is important for sending messages from the brain. When there is damage to the spinal cord, there can be issues with sensing and controlling motor functions in the body. There are many conditions that can affect the function of the central nervous system. Some examples include:
Symptoms of diseases of the central nervous system depend on which part of the brain is affected. Other common symptoms may include changes in mood, changes in motility or tremors, headaches, changes in vision, and more.
The peripheral nervous system is all the nerves in the body except the central nervous system. Nerves are extensions of nerves called axons that send electrochemical signals. The components of the peripheral nervous system include the afferent and efferent nervous system. The efferent nervous system can be further divided into the somatic and autonomic nervous systems.

The afferent nervous system is the sensory system, which sends information from the body to the brain. The efferent system is the motor system, which sends messages about movement from the brain to the body parts it controls, such as the glands and muscles.
The somatic nervous system is the part of the nervous system that is under human control, while the autonomic nervous system is the part of the nervous system that is not under human control.
The peripheral nervous system can be divided into the autonomic and somatic nervous systems. The autonomic nervous system deals with processes that are not under human control, such as heart rate, breathing, digestion, performance and more. The autonomic nervous system innervates the internal organs, allowing them to function automatically. The somatic nervous system controls the systems under the control of the person. This includes things like talking, walking, and typing. The somatic nervous system includes the skeletal muscles that control these processes.
The autonomic nervous system can be further divided into two parts, the sympathetic and parasympathetic nervous system. The sympathetic nervous system controls the “fight or flight” response and is activated during stress. For example, if a person were to trip and fall on the street, this would stimulate a sympathetic nervous system response. That person’s pupils would dilate, their heart would race, and their breathing would increase. This is the body’s response to the presentation of a threat (like the threat of being run over by a car for example) and allows the survival instinct to kick in and take over.

The parasympathetic nervous system is known as the “rest and digest” part of the nervous system. This part of the nervous system controls our digestion and relaxation responses and generally counteracts the effects of the sympathetic nervous system. For example, if a person were to eat a large meal and feel drowsy afterwards, this is the effect of the parasympathetic nervous system which slows down the body and promotes digestion.
The ball comes to you and you swing your bat. A big dog jumps in front of you and you start sweating. You walk past the bakery and the aroma makes your mouth water. All these activities are possible because you have a functioning nervous system. Your nervous system is a complex collection of nerves and cells that carry messages and control actions.
It has three main functions. First, it detects changes going on inside and outside of your body. This is possible because of the sensory receptors found throughout your body and concentrated in your sensory organs, such as your eyes, ears, tongue, nose and skin. Your nervous system reinterprets the information from the sensory receptors, and then responds by sending a command to your muscles or joints. For example, when the pitcher picks up the ball and throws it toward you, your eyes see the ball, your mind swings, and your arms move.

Nervous System Structure & Function
I would definitely recommend to my colleagues. It’s like the teacher waved a stick at me and gave me a task. I feel like it’s a way of life.
The nervous system is a collection of cells, tissues and organs that process information, assess the environment, and control thoughts, feelings and actions. The nervous system is made up of cells called neurons, which send electrochemical signals. The nervous system is divided into two parts:
The peripheral nervous system is divided into the afferent division, which sends information from the body to the brain, and the efferent division, which divides the motor and sends motor information from the brain to the glands and muscles. The efferent division is further divided into the autonomic nervous system, which controls involuntary processes, such as digestion and breathing, and the somatic nervous system, which controls consciously controlled processes, such as walking and speaking. The autonomic nervous system is divided into two additional parts. The sympathetic nervous system controls the body’s “fight or flight” response and the parasympathetic nervous system controls the “rest and digest” response.
This is a nice, neat way to look at the nervous system, but it’s actually an intricate system made up of billions of cells that perform countless tasks every minute of the day. To better understand how the whole system works, we will consider two main parts: the central nervous system and the peripheral nervous system. The central nervous system, or CNS, consists of the brain and spinal cord. It’s the part that interprets incoming sensory information and then issues commands, so I like to think of it as a manager.
Peripheral Nervous System
The peripheral nervous system, or PNS, is made up of nerves that travel to and from the central nervous system. It reports any emotional changes in the brain and spinal cord, and then carries out instructions. So, you can say that PNS is like workers.
The peripheral nervous system is further divided, giving us two main divisions. This is easy to understand if you remember that some of the PNS nerves travel toward the brain, while others travel away from it. Nerves that travel to the brain form sensory divisions or separate divisions. Nerves in this division take information from sensory receptors and deliver it to the CNS, such as the startling sound of a barking dog or the wonderful smell of freshly baked bread. In other words, sensory separation allows you to feel the word around you.
Nerves traveling away from the CNS form the motor division, or efferent division,
