Research Paper On The Nervous System

The nervous system is a multiplexed body system that controls most other body systems directly or indirectly by sending and receiving signals through a complex system of nerves. As a whole, the nervous system can be broken down into the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord while the PNS is composed of peripheral nerves that branch off of the spinal cord and continue to branch to reach the most distal points of the limbs. The PNS can be further broken down into the afferent and efferent division. The afferent division deals with information brought to the CNS from the nerve receptors. Furthermore, the afferent division breaks down into somatic sensory receptors whose

The nervous system is one of the body’s complex functions that contain a network of cells and nerves that transmit signals from the brain and spinal cord to different areas of the body. It is categorized into two groups; the central nervous system which is made up of the brain and spinal cord, and the peripheral nervous system which contains the body’s nervous tissue and is where neurologic responses occur. Homeostasis, which is the process in which thermoregulation is maintained, also happens in this area.

The nervous system is a chain of interconnected nerve fibers which is constructed by the central nervous system and Peripheral nervous system. The job of the nervous system is to send messages from the brain and spinal cord to different parts of the body.

Whereas the spinal cord (often referred to as the brainstem) is the pathways that enables nerve impulses to reach their various destinations in the body. The central nervous system main function is to receive information from the different parts of the body, in which must be analysed and stored in order for it to send out instructions based on those pieces of information. The central nervous system’s main function is to coordinate the numerous organs and muscles required to perform the individual’s desired action(s) (Walker, 2005).

The peripheral nervous system serves the areas in the extremities of the body. The nerves within that system provide a number of functions, depending upon which one is being affected. Typically, nerves can be classified as sensory (receiving sensation), motor (controlling muscle movement) and autonomic (regulating functions such as heart rate and blood pressure). One of the issues that may occur with those nerves is peripheral neuropathy. A number of symptoms of the condition may be experienced.

The components of the nervous system that are involved in physical sensation are Central Nervous system and Peripheral Nervous System. “The Central Nervous System’s role is to integrate, process, and coordinate sensory and motor commands” (Bartholomew). CNS controls only the spinal cord and the brain. The PNS controls the nervous system outside the spinal cord. The function of PNS is to send “sensory division to the central nervous system to be process” (Bartholomew).

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 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.

The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart, stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls many organs and muscles within the body. Rather bizarrely we are unable to determine or feel its presence in our bodies as it is working involuntary, as a reflexive manner. A common example of this involuntary action is best understood when

The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

The nervous system has three main functions: gathering sensory information from external stimuli, synthesizing that information, and responding to those stimuli. The CNS is mainly devoted to the "information synthesizing" function. During this step in the process, the brain and spinal cord decide on appropriate motor output, which is computed based on the type of sensory input. The CNS regulates everything from organ function to high-level thought to purposeful body movement. Thus, the CNS is commonly thought of as the control centre of the body.

There are two parts to the nervous system which are: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord and some nerves, whereas the peripheral nervous system includes all the other nerves and it carries information to the central nervous system and also from it. The central nervous acts as the central control region of the human nervous system. The CNS processes information and issues commands around the body. The autonomic nervous system is the command network the CNS uses to maintain the body 's homeostasis. It regulates heartbeat and controls muscle contractions in the walls of blood vessels, digestive, urinary, and reproductive tracts. It also carries messages that help stimulate glands to secrete tears, mucus, and digestive enzymes.

Everyone is different, we are all built differently, the nervous are the main reason why we are different. so what is the nervous system. 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 and our life.The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc.

The neurons connect to each other to form the neurological circuits. These are information highways that travel by electrical signals. The neurons of the peripheral nervous system combine to form pairs of spinal nerves and cranial nerves. The autonomic nervous system sends axons from the brain stem and spinal cord to various areas of the body such as the heart muscle, the digestive system and the pupils of the eyes.

The central nervous system and the peripheral nervous system work together to collect information from within the body and from the environment outside it. The systems process all the collected information and send instructions to the body; to obtain an appropriate response. Once the data arrives, the brain will sort and file it before sending out any commands on what to do. The central system is the main command center of the body that contains the brain as well as the spinal cord. The peripheral nervous system contains a network of nerves that connect the rest of the body to the central nervous system.

The past, no I’m not talking about the past like in history but actually what we call “now”, the newest moments in time and why we can never be fully aware or live in what we call “now” because it takes time for our brain to process the information about what is happening “now” and it takes that time for that information to get from our body to our brains. In fact the taller you are the further you are from “now”, the further from the past you live. But the deeper questions is how does our brain perceive time? How much time it does it take for the brain to receive the what we see now? Can are brains see into the future? To answer these questions we need to delve into how the human brain and time correlate together.
