Physiology Individual body functions with the nervous system. The nervous system is divided into two parts, central nervous system and the peripheral nervous system. The central nervous system consists of brain and spinal cord whiles the peripheral nervous system consists of the nerves, such as cranial nerves. Cranial nerves job is to connect the central nervous system to the different types of organ in the body. Our neurons consist of cell body which holds the genetic information needed to make protein. Dendrites receive impulses from other cells at the synapses and transmitted them to the cell body. Axon carries outgoing information to its target cell. Neuron has only one axon that includes Axon Hillock. Axon Hillock is the originate place for action potential; Axon collaterals are the branches of axon; Axon terminals which are the sites of neurotransmitter release. The body neuron usually generates an electrical signal and this result in the release of neurotransmitter. The neurotransmitter purpose is to serve as a chemical messenger that enables cell communication among other cells. Myelin sheath is insulation that wraps around the each axon for about 20 to 200 times. Their segments are significantly separated from each other by node of Ranvier, and the Myelin sheath function to increase the conduction velocity of action potentials. Myelin can be produce in either the CNS or the PNS.
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.
Neurons, nerve cells, have three basic parts: the cell body, dendrites, and axon. Neurons transmit signals to other nerve cells and throughout the body. They are simple components in the nervous system. The cell body includes the nucleus, which is the control center of the neuron. The dendrite branches off the cell body and receives information. The axon is attached to the cell body and sends information away from the cell body to other cells. When the axon goes through myelination, the axon part of the neuron becomes covered and insulated with fat cells, myelin sheath. This increases the speed and efficiency of information processing in the nervous system. Synapse are gaps between neurons, this is where connections between the axons and dendrites.
7. Myelin Sheath whitish fatty segmented sheath around most long axons. It protects the axon, electrically insulates fibers from one another , and increases the speed of nerve impulse transmition.
1. Neurons is a basic building block of the nervous system. The sensory nerves carry the message from body tissues to the brain and spinal chord to be processed. The motor neurons are then used to send instructions to the body tissue from the brain and spinal cord. Dendrites, which are connected to the body cell (soma) receive information and pass it through the axon. Myelin sheath covers the axon and helps speed the process. When triggered by a signals from our senses or other neurons, the neuron fires an impulse called the action potential. The resting potential is the neuron’s visual charge of positive
Continuing on we as a class learned about the spinal cord, which is a column of nerves lining our back, as well as the central nervous system, which is the human body’s main processing unit. Chapter two focuses primarily on these two aspects of the body. The central nervous system is the brain and spinal cord, the brain, hindbrain, and midbrain are in charge of the senses. Hearing and sight for example are dealt with in the forebrain. The nervous system includes many different working pieces that control the body. Such as Dendrites; these are the hairs on the neurons. Ions have both negative and positive neurons which each has three, included with the soma in the cell body. Axon is the long tube of it, and the terminal button is the end of the tube.
Multiple Sclerosis, commonly known as MS is an autoimmune disease of the central nervous system. Scientists have been studying MS since the 19th century. In MS, the body’s immune system produces cells and antibodies that attack myelin in your brain which is essential for the nerves in your brain and spinal cord to conduct electricity to perform its function. The attack on myelin results in vison loss, paralysis, numbness, muscle weakness, difficulty walking, stiffness, spasms, and bladder and bowel problems. MS has varying degrees of severity and affects people between the ages of 20-50, mostly women. Although there are treatments, there is no cause and cure yet.
Myelin, found only in vertebrate nervous systems, is a fatty substance that surrounds the axons and long dendrites of nerves in the brain and spinal cord tissue (4). By lowering the rate at which the axonal membrane absorbs nerve impulses, myelin acts as an insulator, allowing NS potentials to travel rapidly through the nervous system and maintain communication between the brain and the rest of the body (2). This communication between the brain and the rest of the CNS and peripheral nerves is a central
Neurons are made up of four parts which are the dendrites, the soma, the axon and the myelin. Dendrites are the branches of the neuron which receive messages and are attached to the soma. The soma contains the nucleus and is mainly responsible for keeping the cell alive and running. Axon is the message carrier of the neuron and it does so as a fiber attached to soma. Lastly, the myelin is a fatty substance made by glial cells that serves as a protecting sheath around the axons. It also speeds up the neural message traveling down the axon.
Multiple sclerosis (MS) is an autoimmune disorder that causes the immune system to attack myelin sheath causing neurological damage to areas of the brain and causes neurological deterioration. In the brain the myelin sheath is involved with what allows for communication between brain and the body. As the disease progresses the sheath deteriorates the neurons where the myelin sheath is found is damaged, causing a break or loss of information when the brain is trying to communicate with the brain. As the central nervous system (CNS) is deteriorating it causes permanent damage that is incurable. The symptoms are not as
The first written report of multiple sclerosis was in 1400, when Lydwina of Schieden was diagnosed. The disease was described clinically by Jean-Martin Charcot in 1877. He recognized that the disease affected the nervous system and tried remedies, with no success. In 1890, suppression of sweat was thought to be the cause of multiple sclerosis, treatment was electrical stimulation and bed rest. By 1910, multiple sclerosis was thought to be caused by toxins in blood. In the 1930s, poor circulation was yet again believed to cause multiple sclerosis. In the 1950s through the 1970s, multiple sclerosis was thought to be causes by allergies. It wasn’t until the 1980s when multiple sclerosis was finally understood and treatment was developed (Campanella and Zawada).

Multiple Sclerosis is a disease that attacks the brain and spinal cord, the central nervous system. Scientists believe that the disease is caused by an environmental factor that certain genetics are predisposed to respond to. Symptoms can vary from person to person but the most common are blurred vision, loss of balance, poor coordination, slurred speech, tremors, numbness, extreme fatigue, memory problems, paralysis, and blindness. In order to be diagnosed with Multiple Sclerosis, a careful history of symptoms is taken, as well as history of birthplace, family, environment, and other illnesses. A variety of tests are run to rule out other conditions that may have similar symptoms. Most of the people who are diagnosed with Multiple Sclerosis are between the ages of twenty and fifty; yet there are people as young as two and as old as seventy-five who have developed the disease. Although the life expectancy for this disease has increased, Multiple Sclerosis
Multiple sclerosis is considered a nervous system disease that affects the brain and spinal cord. The disease remains a mystery to this day since there are no known specific causes. It can be seen that multiple sclerosis is more prevalent in women than in men between the ages of 20-40 (Bethesda 2015). While the disease is typically mild in most cases, some severe cases may result in the loss in the ability to speak, walk, and write. Common symptoms of the disease include “visual disturbances, muscle weakness, trouble with coordination and balance, sensations with numbness and prickling, and thinking and memory problems” (Bethesda 2015). It is important to become more aware and informed on the basics of multiple sclerosis so that in the case if you or someone you know may be experiencing symptoms, an early diagnosis can be made and treatment can start as soon as possible.
Multiple sclerosis (MS) is a degenerative and potentially debilitating disorder that affects the spinal cord and brain, collectively known as the central nervous system. Multiple sclerosis evolves gradually throughout time and is considered to be auto-immune, which means the immune system mistakenly attacks healthy cells and tissues that are supposed to be within the body. According to Medscape, symptoms consist of, but are not limited to, sexual problems, ataxia (the inability to control certain muscle movements as defined by Tortora and Derrickson), fatigue, and optic neuritis. Multiple sclerosis is characterized into four different types: relapsing-remitting MS, secondary-progressive MS, primary-progressive MS, and progressive-relapsing MS. There is currently no cure for multiple sclerosis, but there are many forms of treatments to help suppress the symptoms and hinder the progression. The Patient Education Institute lists of treatments include prescription medication and healthy lifestyle habits, such as exercising. Steroids are also administered to delay the severity of the attacks. The aforementioned details about the treatments, types, and symptoms of multiple sclerosis are merely a superficial analysis. To fully understand this disease, a more in-depth and detailed focus of its impact within the body is needed.
In the article, “Multiple Sclerosis”, a group of medical doctors provided detailed information about clinical course, diagnosis and treatment of MS. According to this article, MS is an autoimmune disease of the central nervous system and spinal cord, which attacks the myelin, the protective covering of the nerves. Signs and symptoms differ from patient to patient. In the early stage, the disease manifests in tingling, impaired sensation, vision problems but as it progresses some of the patients lose the ability to walk independently. Eventually, the disease causes the nerves to deteriorate or become permanently damaged. Neurologists, doctors who care for MS patients, diagnose the disease through a neurological examination and MRI scan. Not
