Autonomic Nervous System

Autonomic Nervous System

The autonomic nervous system is an integral part of the nervous system. They can’t differentiate between the Central Nervous System & Peripheral Nervous System. CNS & PNS are both different things. They are not related to the Autonomic Nervous System or ANS. They come from both CNS & ONS. But their working field is completely different. From the structural purpose, they belong to the CNS & PNS. But they only act upon the smooth muscles & organs....

Anatomy of the Autonomic Nervous System

There is not typically no anatomical structure present. As Autonomic Nervous System is developed with only the help of neurons. There are no other cells present. But still, the Autonomic Nervous System can be divided into three parts....

Types of Autonomic Nervous Systems

As per the function of the ANS, scientists have divided them into two parts. These two parts work simultaneously to provide a better communication bridge. All of these divisions have their equal contribution to human actions....

Sympathetic Nervous System

This is the first component of the ANS. This nervous system is also known as the Thoracolumbar. As this nervous system developed from the Thoracic & Lumber region of the Spinal Cord. They are also often termed Fight or Flight Nervous Systems. As this nervous system only acts when there is a sudden excitement in the body. It regulates the body component in a very unique way....

Parasympathetic Nervous System

This is another component of the ANS. This nervous system is also known as the Craniosacral. As this nervous system is developed from the Sacral Region of the Spinal Cord & Brainstem. Also, this has another name. It is often called the Rest or Digest. This means this nervous system can only able to work when there is no excitement. When the human body is at complete rest, it starts working....

Importance of Autonomic Nervous System

Autonomic Nervous System is very important to the human body. It helps to provide reflex action of the human body while in unconsciousness. If a human body feels excited for any reason the ANS will start acting. Without it, a human can’t able to regulate the body’s functions properly. It doesn’t provide necessary actions to the organs. Rather, it helps to demonstrate an internal change in the mechanism. The organs will act differently under different conditions. When there is no excitement, then there is a need to reduce the pressure. For that purpose, ANS reduces heartbeat to make a normal situation. In absence of ANS, the human body will not show proper behavior. In the absence or disorder of the ANS will be a life-threatening issue. So, there is no proper word to state the importance of ANS in the human body....

Functions of the Autonomic Nervous System

The function of the Autonomic Nervous System is to maintain proper balance in the human body. SNS helps to contract the smooth muscle cells & PNS dilutes the smooth muscle cells. The same thing goes for the heart muscles also. Mainly SNS & PNS works as contradictory to each other....

Clinical Significance

Autonomic Nervous System connects every part of the body. So, damage to this nervous system will create severe problems. Most of the time, the symptoms can be shown at a very late stage. At those times, it will be hard to repair the damages. But still, there is some problem that occurred due to malfunction of the Autonomic Nervous System....

Autonomic Disorders

Autonomic Neuropathy: This is a special type of disorder of themic Autonomic Nervous System. In this disease, when nerve cells get damaged. This affects the autonomic body functions. In this disease blood pressure, and digestion might get affected. Multiple System Atrophy: This is a very rare case. In this case, the motor neurons get affected with time. Individuals who are in their 50s might get affected. In this disease, the motor neurons are damaged. And with time, they need to use wheelchairs. Pure Autonomic Failure: This is a serious disease when the total Autonomic Nervous System gets collapsed. This is the final stage of any nervous system disease. In this disease, an individual losses ability to sweat, sudden changes in blood pressure, etc. Dysautonomia: This is a disease that gets from genetic inheritance. In this disease, there is a problem with the development of the nerve cells in the Autonomic Nervous system. In this disease, individual losses the ability to sense pain. Also, in this disease, there is no tear production. Baroreflex Failure: In this disease, the Afferent Nerves get affected. So, in this disease, blood pressure can’t be measured. Also, in this disease, the blood pressure changes rapidly....
