nervous system

nervous system pain: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. The nervous system guides everything a person thinks, says or feels. It also plays an important role in the things the body does without thinking such as breathing, blushing and blinking.

The nervous system affects every aspect of health including the following

  • Thoughts, memory, learning and feelings
  • Movements, such as balance and coordination
  • Senses of brain such as hear, taste, touch and feel
  • Sleep, healing and aging
  • Heartbeat and breathing patterns
  • Response to stressful situation
  • Digestion, as well as control the feelings of hunger and thirsty
  • Puberty and body sexual desire.

The complex system is the command center for the body. It regulates the body’s systems and allows the individual to experience the environment. 

The nervous system pain works in such a way that a vast network of nerves sends electrical signals to and from other cells, glands and muscles all over the body. These nerves receive information from the surroundings. Afterwards, the nerves interpret the information and control the person’s response. It works like an enormous information highway or chain expanded throughout the body.

Introduction

The nervous system is the part of a person’s body that coordinates its behavior and transmits signals between different body areas. At the cellular level, the nervous system is defined by the presence of a special type of cell, called the neuron, known as a nerve cell. Neurons have special properties that allow them to send signals rapidly and precisely to other cells. They send these signals in the form of electrochemical waves traveling along thin fibers called axons, which cause chemicals called neurotransmitters to be released at junctions to other neurons called synapses.

A cell that receives a synaptic signal from a neuron (a postsynaptic neuron) may be excited, inhibited or other modulated. The connections between Neurons from neural circuits that can generate very complex patterns of dynamical activity. Along with neurons, the nervous system also contains other specialized cells called glial cells (or simply glia), which provide structural and metabolic support. Recent evidence suggests that glia may also have a substantial signaling role.

In vertebrates, it consists of two parts. Each part contains billions of neurons or nerve cells. These special cells send and receive electrical signals through the body.

These components of the nervous system are given below.

Central nervous system (CNS)

Central nervous system (CNS) is made up through the brain and spinal cord. The brain functions the nerve to send messages to the rest of the body. Each nerve has a protective outer layer called myelin. Myelin insulates the nerve and helps the messages get through the whole nervous system (CNS).

Peripheral nervous system

The peripheral nervous system pain consists of many nerves that branch out from the central nervous system (CNS) all over the body. This system relays information from the brain and spinal cord to the body organs, arms, legs, fingers and toes. The peripheral nervous system contains its two components.

  • Somatic nervous system
  • Autonomic nervous system

Somatic nervous system

Somatic nervous system commended the voluntary movement of the body.

Autonomic nervous system

Autonomic nervous system controls the activities which occur suddenly on the friction of time before the reaction time of the brain and do without thinking about them.

The nervous system along with the endocrine (hormonal) system works to control all activities within the human body.  It does this by communicating messages between the brain and the body very quickly using nerve impulses (action potentials). 

The four main functions of the nervous system are given below

  • Control of body’s internal environment to maintain ‘homeostasis’
  • Programming of spinal cord reflexes
  • Memory and learning
  • Voluntary control of movement

Control of body’s internal environment to maintain ‘homeostasis’

Nervous system works to regulate the body temperature. When the person practices  exercises. In order to maintain a relatively constant core temperature the nervous system sends messages to the blood vessels to dilate (expand), increasing blood flow to the skin, and increasing sweating to help disperse the accumulating heat.

Programming of spinal cord reflexes

Programming of the spinal cord is the stretch reflex. This reflex functions to protect us from injury. If there is any case of accidental injury to any of the body parts. The stretch reflex would instantly sense the stretch in the muscles around the injured place and send messages to those muscles telling them to contract and resist the stretch.  This reflex serves to protect the ankle from breaking and results in a minor sprain rather than a severe break.

Memory and learning

The nervous system components are spinal cord and brain. It works as the storage of all the knowledge and learning. A certain amount of repetition was required to learn and memorize these key functions.  The same applies with exercise.  New movements, especially complex ones, take time for the nervous system to learn. 

Voluntary control of movement

Every voluntary movement that a person performs is under the direct control of the nervous system as the nervous system sends the messages to the particular body parts to move.  If the movement has been repeated numerous times, the movement will be very efficient.  If however the movement is new and still requires some repetition then it is expected the movement to be less efficient and in some cases look awkward and ungainly.

How does the nervous system detect and interpret pain

Nervous system works miraculously to detect and interpret the nervous system pain. The two main parts that form the nervous system, the brain and spinal cord, which in combination forms the central nervous system, including the motor and sensory nerves which make up the peripheral nervous system. 

In the case of nervous system pain the brain and spinal cord receive signals from the nerves while sending out large patterns of signals to the muscles controlling the arms, legs and spinal movements. The spinal cord consistently receives updates to the sensors that detect the muscle flexibility, endurance and strength.

So in a nutshell, sensory nerves send impulse updates to the brain through the spinal cord. The brain then sends updates to the motor nerves, which is the reason the person feels pains at the particular part of the body.

Moreover, in the case of a sudden accident, the Autonomic nervous system controls the activities which occur suddenly on the friction of time before the reaction time of the brain and do without thinking about them.

 Conclusion

The nervous system works in such a way that a vast network of nerves sends electrical signals to and from other cells, glands and muscles all over the body. These nerves receive information from the surroundings. Afterwards, the nerves interpret the information and control the person’s response. It works like an enormous information highway or chain expanded throughout the body. In the case of nervous system pain the brain and spinal cord receive signals from the nerves while sending out large patterns of signals to the muscles controlling the arms, legs and spinal movements. The spinal cord consistently receives updates to the sensors that detect the muscle flexibility, endurance and strength.
