Guillain-Barre syndrome (GBS) is an autoimmune disorder of rapid-onset muscle weakness as a result of damage to the peripheral nervous system. The peripheral nervous system is the portion of the nervous system that is outside the brain and spinal cord. Autoimmune means an illness that occurs when the body tissues are attacked by its own immune system. In this case they begin attacking nerve cells which communicate with muscles. They attack the myelin sheaths surrounding the axons of the nerve cells

people with epilepsy loose control over their body through seizures? Well the answer lays in the mechanism of cell communication. Cells communicate in order to perform any activity or work in your system. When an epileptic seizure attack is performed Paracrine and Synaptic signaling in the nervous system in charge of cell communication isn’t working properly. To begin with Paracrine signaling works with a cell that secrets substances by vesicles‚ released to the extracellular fluid where substances

as a nervous system. Neurons like all cells come in different shapes and sizes but are always made up of a cell body attached to a process which is an extension of a neuron; groups of neurons are called neural system and each system having its own special role and function. Neurons are found all over the body although mainly found in the brain and make up to main nervous systems. The central nervous system which is made up of neurons in the brain and spinal cord‚ and the peripheral nervous system

nerve impulses. Myelin is produced by two different types of Glial cells‚ Oligodendrocytes produce myelin in the central nervous system (Brain and Spine) and Schwann cells produce myelin in the peripheral nervous system (Outside Brain and Spine). If myelin is not properly maintained‚ the transmission of nerve impulses could be disrupted and as myelin deteriorates nervous system functions can be impaired. Alexander disease targets the CNS. Causes ALX is caused by a mutation in the GFAP (Glial fibrillary

detected by the body’s nervous system. These changes are detected‚ interpreted and responded to. By sending electrical and chemical impulses the nervous system sets in place reactions to counteract these conditions. An example of this is if you where to place your foot on a sharp object‚ pain is detected by nerves or receptors in your foot and send a message through your foot‚ leg and into your spinal cord and into the brain which forms part of your central nervous system. This signal is interpreted

They are designed to reproduce or substitute for neurological and physiological function that has been lost to injury or disease. Wearable electrical stimulation systems deliver impulses to peripheral nerves. They induce a variety of beneficial effects‚ including muscle building‚ relaxation of spastic muscle‚ improvement

what we are seeing. Our brain then computes to pick up the box. When a message comes into the brain from anywhere in the body‚ the brain tells the body how to react. the brain as a central computer that controls all bodily functions‚ then the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this through the spinal cord‚ which runs from the brain down through the back and contains nerves that branch out to every organ

Heroin is a highly addictive analgesic drug. Heroin‚ which is a popular choice of drug in America‚ is not a new drug that magically popped up in the late 1960’s. In the mid 1800’s opium was a popular drug. Opium was brought to the country by Chinese immigrants who came here to work on railroads. In the old west alcoholism as a big problem and opium was promoted as a cure for alcoholism. Before it was illegal opium was developed as a pain killer in 1810. “It was considered a wonder drug because it
