Nervous System

The Nervous System is followed by a regulator reformation of nerves that controls the entire human body's function from the very centre.

In the human nervous system, nerves are the bunch of axons that are perceptually conducting The Nervous System. The human nervous system is acting out as a communicative and informative system carrying out the overall signals. This has been identified as the core function of the central nervous system followed by cooperation in communicating information. The following description has been included by the human nervous system alongside the function of nerves and the central nervous system. 

What are nerves in the human body?

According to body function, it has been identified that there are almost 7 trillion nerves located in an adult human body. There are some major nerves such as the cranial nerve, spinal nerve, facial nerve, accessory nerve, vagus nerve, oculomotor nerve, trochlear nerve, and many more. Among all of these, the sciatic nerve has been considered to be the main nerve of the entire body.  This particular nerve is responsible for originating and coordinating the entire human function: the baseline of the spinal cord followed by the root of each leg. 

Explain the central nervous system

The central nervous system of the human body consists of the brain and spinal cord that makes up all the peripheral nerves. The central nervous system is the major driver of all the human body functions that control the signals of the brain. The central nervous system transmits signals from the brain to our body parts to make a uniform function of the brain and body. The main component of the central nervous system is the neurons and a human brain contains nearly 100 billion neurons. A neuron refers to the cell body that has a cell nucleus and axons in the extension part. Further, a bundle of axons found in the body is defined as the nerves for controlling signals from the brain.

A brief description of the human nervous system

The human nervous system has two major parts that are the brain and the spinal cord. The peripheral nervous system contains nerves that branch off from the spinal cord and extend to the other parts of the body. The basic component of the central nervous system is the nerve cell that is defined as the neurons. The spinal cord in the central nervous system is the way of communication from the brain to the other parts of the body. A neuron has a cell nucleus, an axon and dendrites to transmit signals from the brain to the other body parts through the spinal cord.

Components of the human nervous system

The main two components of the human nervous system are the brain and spinal cord. The basic unit of the human nervous system is the neurons that make the nerves transmit signals from the brain to the other body parts. The nervous system also consists of non-neuron cells like glia. Glia helps to maintain the normal working condition of the nervous system in any adverse situation. Glia crates myelin that helps to move the nerve impulses in the body.

Effects of the nerves on the nervous system

The bundle of axons in the nervous system called nerves controls the most complicated human body functions: movement, memory and thought. The verve ears affect the human body’s function by creating impulses in the spinal cord to transmit information from the brain to the body. The vast network of nerves helps to transmit information within the cell body to manage body processes. Nerves interpret the information and help to create senses within the body.

Functions of the central nervous system

The central nervous system helps the natural body movement by creating impulses in the spinal cord. The central nervous system uses neurons to send information from the brain to the human body cell. The signals by the nerves help to move the body parts and create a sensation in the body in the time of pain. Different neurons are sending different signals from the brain like motor neurons are responsible for the muscle movement in the body. Sensory neurons are responsible for the sensation in the body.

Conclusion 

The discussion has been provided with the core context of the nervous system. It has been followed by the human nervous system containing multiple nerves and its precise function.  In this context it has been identified that the nerves have the total control of the human nervous system in terms of communication and features. The potential electrical signal of the nerves of the human nervous system allowed them to transmit the overall information quickly to the entire length of the body.
