The Central and Peripheral Nervous Systems
The human body is a complex organism, it is comprised of numerous individual systems that all work together to maintain the living body. Working as the chief system in the body is the Nervous System. The Nervous System as defined by ( Miriam Webster, 2014) is “a system of nerves in the body that send and receive messages for controlling movement and feeling between the brain and the rest of the body.” The Nervous System is further complex and divided into 2 systems that work together to process and perform all voluntary and involuntary functions.
Much like a computer the body has a central processor unit called the Central Nervous System or CNS. This system is comprised of 2 core units; the Brain and the Spinal Cord. According to the (U.S National Library of Medicine, 2014) “they work together and serve as the main "processing center" for the entire nervous system, and control all the workings of the body.” The Brain receives information from a variety of stimuli and uses the spinal cord to send and relay messages to the Peripheral Nervous System or PNS.
The Peripheral Nervous System’s main purpose is to connect the central nervous system to the limbs and organs to execute commands. The PNS is further divided into 2 systems; the somatic (voluntary) nervous system and the autonomic (involuntary) nervous system. These 2 systems process and execute voluntary commands like walking or speaking and involuntary commands such as breathing and sweating. The PNS also works as a pathway to relay sensations or stimuli back to the CNS.
Both the CNS and PNS communicate via neurons. Neurons are nerve cells that consist of den...

...ance. TBI can also have adverse effects on cognitive task such as speaking, memory and processing information. A person with this type of injury may find it difficult or impossible to communicate the want for ice cream. Lastly psychological injuries can drastically change or affect a person’s personality. The Nervous System plays a crucial role in our everyday life and we often take for granted all of its task and funtions.

Unless it is extreme, you would not guess it. When most people met with the McKays, they said that they had no idea they suffered from disabilities. These injuries can affect a person in different ways that we do not understand. Sometimes even doctors struggle to understand brain injury, which can cause a lot of trouble for people who are suffering from TBI.
The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from the CNS, to transmit information to your limbs and organs, for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain. Nerve cells generate electrical signals to transmit information.
The body is controlled down to its core by the central nervous system. The central nervous system consists of the brain and the spinal cord. Both of these are made up by white and gray matter. The brain which has gray matter on the outside and white matter on the inside is responsible for processing the information that it receives from the nerves and spinal cord, sending out responses, and coordinating motor functions. The spinal cord is opposite of the brain and has gray matter on the inside and white on the out. The spinal cord conducts the information or messages it receives from the brain to the body and sends its “research” back to the brain for processing.
The ANS is part of the peripheral nervous system, being split into sympathetic pathways, which prepare the body for action and parasympathetic pathways which prepare the body for rest. This regulates the functions of the body and some of the muscles automatically.

The nervous system is the most complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells that sends information to the brain to be analyzed.
The nervous system and the important sensory organs play a key role in the day-to-day
The brain consists of both neurons and glia cells. The neurons, which are cells housed in a cell body called a Soma, have branches which extend from them, referred to as dendrites. From these dendrites extend axons which send and receive impulses, ending at junction points called synapses. It is at these synapse points that the transfer of information takes place.
It is the idea that the mind and body are not separate entities. Rather, they are intricately connected, interacting with each other in many ways. The body's three main regulatory systems are the central nervous system (which includes the brain), the endocrine system (which produces hormones), and the immune system. These three systems work together and affect one another. Researchers who study the mind-body connection examine these interactions, and are particularly interested in the effects of emotions and thoughts on physical health.
The brain is the control center of the human body. It sends and receives millions of signals every second, day and night, in the form of hormones, nerve impulses, and chemical messengers. This exchange of information makes us move, eat, sleep, and think.
The brain and spinal cord make up the central nervous system. The brain doesn't just control your organs, but also can think and remember. That part of the brain is called the mind.
The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!
This arc belongs to the autonomic nervous system (ANS). The ANS is the part of the peripheral nervous system that is responsible for controlling involuntary body functions. This system helps us maintain a steady heartbeat while we are sleeping, and anything else that is necessary to keep us alive during low levels of consciousness. This system affects the body functions that are not consciously managed, such as breathing, digestion, heart rate, pupillary dilation, and urination. However, there are some ANS actions that we are able to control with our mind to a certain extent, such as swallowing.
Nervous system is one of the major organ systems that is responsible for the coordination of biological activities inside the body through cells called neurons. It is composed of the brain and spinal cord which are surrounded by protective layers of bone and membrane tissues called meninges. There are two major divisions in the nervous system; first one is the central nervous system (CNS) and the other being the peripheral nervous system (PNS). The CNS is composed of the brain, spinal cord, and retina while the PNS includes the sensory neurons, ganglia, and connecting neurons. The nervous system applies control using nerves; almost as if sending a message by a telephone. The nervous system is fast due to its electrical nature. The nerve cells in this system are connected with each other in a complex manner where the neural pathways would be possible. Neural
