What is the nervous system simple definition?
The nervous system controls everything you do, including breathing, walking, thinking, and feeling. This system is made up of your brain, spinal cord, and all the nerves of your body. The nerves carry the messages to and from the body, so the brain can interpret them and take action.

Why the nervous system is important?
The nervous system plays a role in nearly every aspect of our health and well-being. It guides everyday activities such as waking up; automatic activities such as breathing; and complex processes such as thinking, reading, remembering, and feeling emotions. The nervous system controls: Brain growth and development.
How does central nervous system work?
The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components: The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.
What is nervous system of human body?
The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.
What part of the nervous system is affected by depression?
The main subcortical limbic brain regions implicated in depression are the amygdala, hippocampus, and the dorsomedial thalamus. Both structural and functional abnormalities in these areas have been found in depression. Decreased hippocampal volumes (10, 25) have been noted in subjects with depression.
What is nervous system depression?
Central nervous system — or CNS — depression happens when the body’s normal neurological functions slow down. It can result from substance overdoses, poisoning, or other medical conditions. Depression of the central nervous system or CNS often occurs when a person misuses a substance that slows brain activity.
Can you repair your nervous system?
There is no such repair process in the central nervous system, thus injuries often lead to permanent damage such as paraplegia,” explains Claire Jacob, Head of Cellular Neurobiology at JGU.
What is the most important part of the nervous system?
The brain and the spinal cord make up the central nervous system. The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.
What are the 3 functions of nervous system?
The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.
How does the nervous system control the body?
The nervous system controls: Sight, hearing, taste, smell, and feeling (sensation). Voluntary and involuntary functions, such as movement, balance, and coordination. The nervous system also regulates the actions of most other body systems, such as blood flow and blood pressure.
Which drug causes depression of nervous activity?
Depression of the central nervous system is generally caused by the use of depressant drugs such as ethanol, opioids, barbiturates, benzodiazepines, general anesthetics, and anticonvulsants such as pregabalin used to treat epilepsy.
What is nervous system short answer?
The nervous system is a body system which sends signals around the body. It lets animals respond to what is around them. The central nervous system is the brain, the spinal cord, and nerves. It is present in almost all animals. It is there to process the input from the senses, and to to coordinate movement.
What are 5 facts about the nervous system?
11 Fun Facts About the Nervous System
- The body has billions of nerve cells.
- Neurons are made of three parts.
- Neurons may look different from one another.
- Neurons are programmed to do different things.
- There are two parts of the nervous system.
- There are two types of nervous systems.
- The involuntary system is broken down into three parts.
What materials inside your body protects your nervous system?
The brain and spinal cord are covered by three layers of meninges, or protective coverings: the dura mater, the arachnoid mater, and the pia mater. Cerebrospinal fluid surrounds the brain, cushioning it and providing shock absorption to prevent damage.
What drug relaxes the central nervous system?
Sometimes called “benzos,” benzodiazepines are central nervous system depressants that are prescribed to treat anxiety, sleep disorders, convulsions, and other acute stress reactions. Common benzos include Valium, Xanax, and Ativan.
Can we live without the nervous system?
Without the nervous system our brain would be mush. It wouldn’t know anything that was going on in the outside world and wouldn’t be able to control our body. The brain and the spinal cord make up what is called the central nervous system. The rest of the nerves together are called the peripheral nervous system.
How can I cure my nervous system naturally?
- Exercise regularly.
- Do not smoke or use other tobacco products.
- Get plenty of rest.
- Take care of health conditions that may cause decreased nervous system functioning, such as:
- Eat a balanced diet.
- Drink plenty of water and other fluids.
How do you get a good nervous system?
How to keep your nervous system healthy
- Provide the nerves with the supplies they need to transmit messages.
- Protect the nerves with B vitamins.
- Use yoga and stretching to strengthen the nervous system.
- Pursue well-being to improve the health of the nerves.
How do chemicals affect the nervous system?
As adults, chemicals and pollutants can accelerate the rate at which adult nerve and brain cells degrade and die by increasing oxidative stress in the body. This is thought to increase the risk of Parkinson’s and Alzheimer’s diseases, bipolar disorders and chronic fatigue syndrome.
What is nervous system explain with example?
The nervous system is made up of all the nerve cells in your body. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.
