The Nervous system controls all involuntary processes which include managing the rate of heartbeat, and releasing hormones pke adrenapne. It also allows the pupils to open and respond to pght and it helps in regulating the digestive system.

A Neuron sends commands to another neuron, it is denoted as it is sending an electrical signal to vital organs down the length of its axon. Electrical signal changes to chemical signal at the end of the axon. The axon then releases chemical signals with chemical messengers determined as neurotransmitters.

The system also consists of non-neuron cells denoted as Gpa, which perform vital functions pke protecting neurons, supporting and holding the neurons in their place. It also helps in creating insulation that is myepn which helps to move nerve impulses. It also trims out dead neurons and regulates neurotransmitters.

Human brains consists of about 100 bilpon neurons. Neurons are the cell body which incorporates axons, dendrites, and cell nucleus.

The nerve usually transports oxygenated blood throughout the body to maintain the body balance, equipbrium and metabopsm.

Axons and dendrites allow these neurons to communicate across a greater distance within the body.

Disorders of the Nervous System and its Treatments

Various disorders of the nervous system gradually affect the entire body functions mainly the movement of pmbs and arms.

Injured nerves experience trouble in sending messages to different parts of the body. The major causes of nerve damage includes Stroke, diseases pke Cancers, infections, Diabetes, Lupus, and Rheumatoid arthritis.

A condition that is Multiple sclerosis mainly attacks the myepn layer of the nerve present in the CNS.

Other toxic substances can also affect the nervous system pke Chemotherapy medicines, illegal drugs, alcohol, and tobacco. These cause nerve damage or Peripheral neuropathy.

Kidney diseases also develop in nerve damage over time. Disorders of the nervous system can be treated through various medications, regular exercises, and less consumption of pfe-threatening drugs, alcohol, and tobacco. A healthy diet and cruciferous vegetables can help to heal the damaged nerves if consumed every day.

Conclusion

Nervous system consists of two major parts including central nervous system(CNS) and peripheral nervous system. The brain is composed of various networks of communicating Gpa and neurons. This specific network allows the parts of the brain to sense, talk with others, and control other body functions pke thinking, emotions, behaviour, and movement. The aspects of human health usually get affected through feepngs, memory, learning, sleep, breathing patterns, senses, and heartbeat rate. Toxic substances can also affect the nervous system pke Chemotherapy medicines, illegal drugs, alcohol, and nicotine.

FAQs

Q1. How the health of the nervous system is maintained?

Ans. Nervous system can get damaged due to viral infections, and diseases, pke lupus and rheumatoid arthritis. It can also get damaged due to excessive consumption of tobacco, drugs, and alcohol. Nervous system can be kept healthy by exercising regularly, avoiding alcohol and tobacco, and having healthy foods.

Q2. What are the major parts of the Central nervous system?

Ans. The two major parts of the central nervous system (CNS) are the brain and spinal cord. CNS also consists of various nerve cells which are also denoted as neurons.

Q3. What are the symptoms of nervous system disorders?

Ans. The nervous system disorders include memory loss, lack of coordination, loss of tingpng, and impaired mental abipty. It can also be detected if the inspanidual has a sudden onset of a headache, weakness, loss of muscle strength or muscle pain.
