What Is The Main Function Of The Nervous Tissue – Understanding the nervous system. Learn about central and peripheral nervous systems, somatic and autonomic, sympathetic and parasympathetic nervous systems. Updated: 2022-05-02

The nervous system is the 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 Main Function Of The Nervous Tissue

The three main organs of the nervous system are the brain, spinal cord and nerves. The brain is the main processing center of the nervous system. The spinal cord acts as a highway that sends messages between the brain and the body. Nerves are extensions of neurons that enter the body and send messages.

Major Organs And Divisions Of The Nervous System

What is the nervous system? The nervous system is the collection of cells, tissues and organs in the body that facilitate electrochemical communication throughout the body. The function of the nervous system is to enable communication around the body and to help the body maintain homeostasis, or a state of balance. The nervous system consists of specialized cells called neurons that can send electrochemical signals. Neurons send messages between the brain and the body and allow 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 distinct 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 spinal cord.

The brain is the main processing organ in the body. All sensory information about the internal and external environment is brought to the brain, where it is processed. The brain then sends out signals to cause the appropriate response in the body. The brain consists of three main parts: the cerebrum, the cerebellum and the brainstem.

Peripheral Nervous System (human Anatomy): Picture , Functions, Diseases And Treatments

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, each of which has different functions. For example, the occipital lobe processes visual information, while the frontal lobe controls our executive functions, emotional regulation, pleasure, speech, and more.

The spinal cord is like the body’s highway. It carries information from the body to the brain and from the brain to the body. The spinal cord is essential for sending messages from the brain. When there is damage to the spinal cord, there can be problems with perceiving sensations and controlling the motor function of the body. There are many conditions that can affect the functioning of the central nervous system. Some examples include:

The symptoms of diseases of the central nervous system depend on which part of the brain is affected. Some common symptoms may include changes in sensation, changes in mobility or tremors, headaches, changes in vision, and more.

The peripheral nervous system is all the nerves in the body outside the central nervous system. Nerves are extensions of neurons called axons that send electrochemical signals. The parts of the peripheral nervous system include the afferent and efferent nervous systems. The efferent nervous system can be further divided into the somatic and the autonomic nervous system.

The afferent nervous system is the sensory system, which sends sensory information from the body to the brain. The efferent system is the motor system, which sends messages about movement from the brain out to the parts of the body it controls, such as glands and muscles.

The somatic nervous system is the part of the nervous system that is under a person’s conscious control, while the autonomic nervous system is the part of the nervous system that is not under a person’s conscious control.

The efferent peripheral nervous system can be divided into the autonomic and the somatic nervous system. The autonomic nervous system is responsible for processes that are not in a person’s conscious control, such as heart rate, breathing, digestion, childbirth, and more. The autonomic nervous system innervates the internal organs, allowing them to function automatically. The somatic nervous system controls processes that are in a person’s conscious control. This includes things like talking, walking and writing. The somatic nervous system innervates the skeletal muscles that control these processes.

The autonomic nervous system can further be divided into two parts, the sympathetic and the parasympathetic nervous system. The sympathetic nervous system controls the “fight or flight” response and is activated during times of stress. For example, if someone were to trip and fall in the street, this would activate the sympathetic nervous system response. The person’s pupils dilated, their heart raced and their breathing increased. This is the body’s response to being presented with a threat (like the threat of being hit by a car in the example) and allows survival instincts to kick in and take over.

Functional Divisions Of The Nervous System

The parasympathetic nervous system is known as the “rest and digest” part of the nervous system. This part of the nervous system controls our digestive and relaxation responses and generally counteracts the effects of the sympathetic nervous system. For example, if someone were to eat a large meal and feel sleepy afterwards, this is the effect of the parasympathetic nervous system slowing down the body and promoting digestion.

A ball comes towards you and you swing your bat. A large dog jumps out in front of you and you start to sweat. You walk past a bakery and the wonderful aroma makes your mouth water. All of these functions 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 your body. This is possible thanks to sensory receptors located throughout the body and concentrated in your sense organs, such as your eyes, ears, tongue, nose and skin. Your nervous system also interprets the information from sensory receptors and then provides a response by sending out an order to your muscles or glands. For example, when the pitcher winds up and throws the baseball at you, your eyes see the ball, your brain says swing, and your arms move.

I would definitely recommend to my colleagues. It’s like a teacher waved a magic wand and did the work for me. I feel like it’s a lifeline.

The nervous system is the collection of cells, tissues and organs that process information, sense 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 sensory information from the body to the brain and the efferent division which is the motor division and sends motor information from the brain to glands and muscles. The efferent division is further divided into the autonomic nervous system, which controls processes that are not consciously controlled, such as digestion and breathing, and the somatic nervous system, which controls processes that are consciously controlled, such as walking and talking. The autonomic nervous system is further divided into two parts. The sympathetic nervous system controls the “fight or flight” response in the body and the parasympathetic nervous system controls the “rest and digest” response.

This is a neat and tidy way of looking at the nervous system, but in reality it is a very involved system made up of billions of cells that perform countless functions every minute of the day. To best understand how the entire system works, we will consider the two main divisions: 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 the incoming sensory information and then issues orders, so I like to think of it as the boss.

Autonomic Nervous System: What It Is, Function & Disorders

The peripheral nervous system, or PNS, consists of nerves that travel to and from the central nervous system. It reports any sensory changes in the brain and spinal cord and then carries out orders. So you can say that PNS is like the workers.

The peripheral nervous system divides again, giving us two main divisions. This is easy to understand if you remember that some of the nerves in the PNS travel towards the brain, while others travel away from it. The nerves that travel to the brain make up the sensory division or afferent division. Nerves in this division take information from sensory receptors and bring it to the CNS, such as the terrifying sound of a dog barking or the wonderful smell of freshly baked bread. In other words, the sensory division allows you to sense the word around you.

The nerves that move away from the CNS make up the motor division, or efferent division,
