Myelin

When the disease’s systems are seen before, a treatment called Stem Cell Transplantation or HSCT can help stimulates normal development of myelin and reduces neurological symptoms. But after the disease is onset, it's a matter of making the child comfortable until the disease has taken over. Though our next disease only connects by the facts that it and Krabbe Leukodystrophy are both genetic…

across the membrane instigating electrical potential to fall (Multiple sclerosis, 2013). Once action potential reaches its end, neurotransmitters are released in the synapse. The myelin coating around nerve fibers affect the speed of the action potential by increasing it. Multiple sclerosis evolves from a lack of myelin coating around the never, without this coating the axon is slowed down, which is slowing the signals being sent and received (Multiple sclerosis, 2013). Because of the lack of…

There are many factors that can affect a person’s development. One of which is isolation. There have been many tests to determine the effects of isolation on children and the makeup of their brain compared to a normal child. Isolation can lead to many mental illnesses over time, some of which can be fixed through therapy and medication. Boo Radley suffered one of these mental illnesses because of his living conditions; however, it is difficult to determine an exact diagnosis with the information…

Abstract The Multiple sclerosis (MS) disease of the central nervous system containing the brain and spinal cord is potentially disabling. With Multiple Sclerosis (MS) the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes a disruption in communication between the brain and the rest of the body. At some point in time, the disease can cause the nerves themselves to deteriorate or become permanently damaged. The signs and symptoms of Multiple Sclerosis (MS) are…

axon, Na+ flow in and cause adjacent areas to depolarize to threshold, sending the action potential slowly down the axon. Conversely, the conduction rate of an action potential is much faster in a myelinated axon. Since ions will not travel across myelin, a separate area must be utilized to permit the conduction of the action potential. At the Nodes of Ranvier,…

There are many types of progressive diseases that do not currently have a known cure. These can be devastating to the patient, family members, friends, and everyone they come in contact with. Three of the most well-known progressive diseases are Amyotrophic Lateral Sclerosis (ALS), Parkinson's disease, and Multiple Sclerosis (MS). ALS, or Lou Gehrig's disease, is a neurological disease that causes nerves to decompose and cause disability. The beginning signs of ALS are often muscle twitching or…

Reaction time is the period that it takes for the body to respond to an action (“Stimulus”) that is often causing a disruption in homeostasis or being a change in the environment (Bradshaw). The system responsible for its function is the nervous system. The nervous system is the answer in how we communicate, move, feel, sense and control ourselves. There are two main parts in the nervous system that are significant because humans depend so much on them. The two parts are the Central nervous…

structure cells that is a barrier for the brain through blood. (2.) Microglial cells are cells that remove dirt and attack microbes. (3.) Ependymal cells are cells that covers and lines the surfaces and cavities. (4.) Oligodendrocytes are cells that makes myelin that holds the nerve fibers in place. What doe the term meninges mean? What are the 3 distinct layers of the meninges? Discuss this in detail. Meninges is membrane…

Everyday our bodies undergo amazing processes, which allow us to complete our daily activities without a thought. The ability for our heart to pump, our nerves to transmit signals, and our bodies to ambulate, are processes that we may take for granted or better yet, not even think about. But the interruption of these “normal” processes can give their victims way more than they bargained for, or even imagined. Daily life no longer becomes the simple task of getting dressed and going to…

to rewards, and is extremely sensitive to, and easily manipulated by social situations. The prefrontal cortex is fully matured around the mid-twenties for a majority of people. The part of the cortex, which hasn’t fully matured is the layer of myelin. Myelin is a layer of fat that insulates the nerves in the brain, this fatty insulation allows electrical impulses to have a faster reaction time, which in turn speeds up…
