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.
- Center: This is the starting point of the ANS. From this part, ANS develops. Depending upon the type or division of ANS, it can be developed from a different area. Like one type is starting from the Thoracic & Lumber region of the Spinal Cord. And another part is coming from the Sacral Region of the Spinal Cord & Brainstem.
- Ganglia: This is the connecting part of the ANS. The neurons which are coming from CNS or PNS area will be left here. From here onwards there will be Autonomic Fibers which will conduct the messages. This acts as the junction of the neurons. Two different neurons joined here to have better communication. Sometimes in some cases, the neurons which are coming from the CNS or PNS don’t stop at the ganglia. Sometimes they travel to the target organ. There they end their journey.
- Autonomic Fibers: These are the neurons that are starting from the Ganglia. After ending the neurons that are coming from the CNS or ONS will end at the Ganglia. Instead of that, Autonomic Fiber will take their position. There are two types of fiber. One is Efferent & another is Afferent fiber. Efferent Fibers will transport the messages from the CNS or PNS to the muscles. Whereas the Afferent Fibers transport the messages from the muscles or organs. This will help to make a two-sided communication.
Autonomic Nervous System
The nervous system is a very complicated structure in the human body. There are millions of neurons are present in a body of a human. The nervous system is the most important component of our body. Human being walks, talk, eat food, etc. all these things are related to the nerves. If there are no nerves present, then there a communication gap will arise. Sometimes, it is thought that the brain is the main component of our body. The brain is controlling the body. But this is not fully a correct statement. The nervous system is a large system where different component plays an important role. The autonomic nervous system is part of the nervous system.
