Informative Speech Outline YOUR NAME Donna Smith Topic: Multiple Sclerosis (commonly referred to as MS) General Purpose: To inform. Specific Purpose: At the end of my speech my audience will be able to describe the effects of Multiple Sclerosis. Thesis Statement: Multiple Sclerosis is an incurable, painful disease, but with the proper treatment it is manageable. Organizational Pattern: Cause and Effect, Problem and Solution Visual Aids: Power Point Presentation, Pictures Introduction…

room. SUDDENLY -- the door is flung open, and her mother dashes in. SARAH (whispering) Under the bed! SUDDENLY -- Stephanie is under the bed, peering out as her mother rises. She sees only feet, and hears the angry animal noise again. Then, she hears what sounds like a struggle, and in an instant, her mother falls to the floor, her face bloodied, as though it has been chewed on. Blood seeps toward Stephanie, under the bed. The creature strokes her face. It is a QALLUPILUK. It has…

Multiple Sclerosis is an autoimmune disease and claims the lives of an estimated 2.5 million people in the world. In Australia, it has been researched that the further away a person is from the equator, the more likely is the person is to develop multiple sclerosis. For instance, in the far north of Queensland the disease occurs 12 in every 100000 people, while in New South Wales, it rises to 36 people out of 100000, and even higher in Tasmania with 76 people out of 100000. Although multiple…

The pathophysiology’s associated with polyneuropathy are symmetrical involvement of multiple nerve fibers, which results in stocking/glove distribution of sensation. In addition, demyelination of distal part long axons because of the increase in myelin. Moreover, degeneration of the distal part of long axon because inadequate axonal transport to distal ends of axons. The pathology of polyneuropathy will lead to several sensory, motor, and autonomic function changes. Primarily, demyelination…

Comparing with other disabilities, diseases, spinal cord injury is a critical disorder in worldwide. Physiology and anatomy The spinal cord(SC) is a grayish-white structure that begins superiorly at the foramen magnum in the skull, where it is continuous with the medulla obolongata of the brain. It terminates at the level of the lower border of the first lumbar vertebra. The spinal cord is located within the vertebral canal of the vertebral column, which is surrounded by three meninges: the…

loss and depression. There is no current cure for MS, but there are promising interventions to assist those diagnosed lead a healthier, more productive life. Definition Nerves in the human body are coated with a protective covering called myelin. The myelin sheath on the nerve fibers speeds the transmission of impulses…

The movie Lorenzo’s Oil is about a young boy named Lorenzo who gets a genetic disorder from his mother called ALD. Adrenoleukodystrophy is a genetic disorder characterized by the loss of myelin. In the film Lorenzo's family the Odones faith leads to the cure that saves their boy and makes medical history. It’s a based on a true story film with a family who battled against the odds to save their son's life. The family's courage and persistence for Lorenzo did inspire me because they never gave…

Describing the Roles of Sensory Receptors, Sensory Neurons and Specialized Sensory Receptors Sensory neurons are nerve cells within the nervous system that convert external stimuli from an individual’s environment into internal electrical impulses that can be transmitted from one neuron to another. For example, taste buds located in our mouth are sensory neurons that work with olfactory receptors in order to determine the flavour of the food. They are able to do this, in simple terms, because a…

million people around the world suffer from Multiple Sclerosis (“Definition of MS,” n.d.). According to the National Multiple Sclerosis Society, the exact antigen whic targets the immune cells to attack remains unknown to this day. Damage to the myelin coating around the nerve fibers in the Central Nervous System and to the nerve fibers themselves interferes with the transmission of nerve signals between the brain, spinal cord and the rest of the body.…

Oligodendrocyte cells wrap around the spinal cord and form the myelin. This insulates the spinal cord and helps the pules to flow quickly and efficiently down the axons. Spinal cord injuries affect both the myelin and the neurons. Spinal cord injuries are very serious as they are debilitating to the individual. As the nervous system is such an important system the impacts are physical…
