The nervous system is the main component that makes us who we are. Just like how a computer needs the hard drive, humans need the nervous system in order to live. The nervous system is a network of nerves (the brain, the spinal cord, and other organs) who work together to allow us to perform daily tasks. It is the humans electrical chemical control center. It is the hub for the body’s functions; it receives, and then generates the transmitted functions through electric signals on what functions the body will perform: communications, coordinating, controls, and regulate (Adam). In order for us to function properly, the system must have all components connected properly.
The nervous system is made of glial cells and billions of nerve cells called neurons. The neurons are the basic fibers of the main signaling unit. The nervous system collects information through the sensory cells and then responds to external stimulants. With the electrical signals sent to the stimulus and then they transmit them to the spinal cord or the brain. The signals are then processed and carried out through the muscles or glands. Each neuron consists of a body cell and extensions. The short extensions (dendrites) are the antennae or the signal receivers. They receive signals and transmit them on to the cell body. Then there are the long extensions (the axon) they are the transmitters. Next is the nerve impulse, which releases the chemical substance, this is the chemical neurotransmitter. The neurons job is to help direct axons to the target. They form an outer fatty layer and wrap around the axon to provide electrical insulation to assist in transmitting signals.
The nervous system has two parts: central nervous system and peripheral nervo...

These are just a few of the known disease that are associated with a nervous system that is not properly connected. In order for us as human beings to have the ability to function properly on a daily basis, the system must have all components connected properly.

The nerves are made of neurons which are the cells that receive, process and transmit messages from one neuron to another. The nervous system is separated into two main parts; the central nervous system and the peripheral nervous system. The central nervous system is made up of the brain and the spinal cord. The second part of the nervous system is the peripheral nervous system which allows the central nervous system to communicate with the muscles, joints, glands and organs.
Neurons dispatch signals to other cells through thin fibers called axons, that cause chemicals acknowledged as neurotransmitters to be released at junctions identified as synapses. A synapse gives a command to the cell and the entire communication process typically takes only a fraction of a millisecond.
A bunch of nerves put together is called the Nervous system. The Nervous system helps with body coordination and provides sensory information about external problems. The nervous system controls the brain, spinal cord, sense organs, etc. Without our nervous system, we would not be able to function, since
...ives to treating Epilepsy and its effects. Typically most doctors will prefer to keep the medicinal treatment as natural as possible. Although not many people have seizure alert dogs, they are out there and available as an alternative. However, if one’s Epileptic seizures are interrupting one’s normal day to day life activities that one partakes in, antiepileptic drugs may be the next step towards Epilepsy management. I have found through research that a corpus colostomy surgical procedure is only performed in severe cases of Epileptic seizures, and is only done as a last step towards treatment. All in all, I have come to find that Epilepsy can be treated and or controlled through the use of these resources. Nonetheless, as with many treatments used to treat Epilepsy, there are positive outcomes as well as possible consequences affiliated with these treatments.
When a message comes to the brain from body parts such as the hand, the brain dictates the body on how to respond such as instructing muscles in the hand to pull away from a hot stove. The nerves in one’s skin send a message of pain to the brain. In response, the brain sends a message back dictating the muscles in one’s hand to pull away from the source of pain. Sensory neurons are nerve cells that carry signals from outside of the body to the central nervous system. Neurons form nerve fibers that transmit impulses throughout the body. Neurons consists of three basic parts: the cell body, axon, and dendrites. The axon carries the nerve impulse along the cell. Sensory and motor neurons are insulated by a layer of myelin sheath, the myelin helps
...ts other than medication. If the medication isn't working the doctor may suggest the Ketogenic diet. The diet will consist of foods that are high in fat and low in carbohydrates and protein. How the diet works is still unclear even though people say that the ketone that the diet helps your body produce is similar to antiepileptic effects. Some other approaches could be behavioral therapy such as desensitization, relaxation therapy, biofeedback, positive reinforcement, or cognitive therapy. The final resort would be surgery. The operations usually involve removal of where the seizures are coming from.
Many people with epilepsy usually have more than one type of seizure and may have other symptoms of neurological problems as well. The cause of epilepsy varies by age of the person, but the majority of the time the cause is unknown. Common causes of seizures by age in Elizabeth Otte’s case would be congenital conditions (Down’s syndrome; Angelman's syndrome; tuberous sclerosis and neurofibromatosis), genetics, head trauma, and progressive brain disease which is rare (Schechter & Shafer, Ltd., 2013, p.1). The diagnosis of epilepsy is based on medical history of the patients including family history of seizures. They ask several of questions to figure of what type of seizures the patients could possibly be suffering from. Doctors then preform test such as EEG, take blood, and study images of your brain. Epilepsy is treated by a neurologist specialist that may or may not subscribe medication depending on the severity and frequency of the seizures. Also treatment can be a change in the patients’ diet or
Epilepsy is a condition characterized by recurrent seizures which are unprovoked by any immediately identifiable cause (Hopkins & Shorvon, 1995). It is also known as a seizure disorder. A wide range of links and risk factors are associated with the condition, but most of the time the cause is unknown. Epilepsy is one of the most common neurological disorders, affecting approximately two and half million people in the US and about 50 million worldwide. Though seizures can occur at any age, epilepsy is most commonly seen in children and the elderly. Most respond well to treatment and can control their seizures, but for some it is a chronic illness. A clinical diagnosis is the first step to finding a potential cure for the disorder.
These electrical signals arise from ion fluxes produced by nerve cell membranes that are selectively permeable to different ions. Neurons and glia (cells that support neurons) are specialized cells for electrical signaling over long distances. Understanding neuronal structure is important for understanding neuronal function. The number of synaptic inputs received by each nerve cell in our (human) nervous system varies from 1-100,000! This wide range reflects the fundamental purpose of nerve cells, to integrate information from other neurons.
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.
Our nervous system interacts with every other system in your body. The endocrine system works with our brain and central nervous system, to control the creation of specific hormones and enzymes. The digestive and excretory systems work with the nervous system in a conscious and unconscious ways. We can't tell our stomach where the food goes after we ingested it. The body is programed to function voluntarily and
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.
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.
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
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!
