cord, and can be a result of a viral infection. Similar symptoms are also seen with Multiple sclerosis and Meningitis such as, vision impairments, and a feeling of weakness or fatigue. The two disorders differ because Multiple sclerosis affects the myelin sheath on the central nervous system cells, and Meningitis specifically affects the meninges that cover the brain and spinal cord. Another difference is that Multiple sclerosis can be associated with genetics, and Meningitis is contracted from others

The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain. Nerve cells generate electrical

the body’s own immune system destroys the myelin sheaths of the affected individuals neurons. MS is a disabling disease because it disrupts the flow of information within the brain and the flow of information between the brain and the body. The cause of MS is unknown but it affects women more than men. Scientists believe the disease is triggered by certain environmental factors to individuals who are genetically predisposed. The antigen present in the myelin and nerve fibers that immune cells target

present in the membrane. The function of these are that they are able to detect a change in the environment and they are able to create an action potential with sodium ions. The schwann cell wraps around the axon and is used to insulate it from the myelin sheath. The cell body is in a ganglion which is close to the CNS. There is also the axon, this is short communication route which is between the cell body and the axon terminals, in this there

rudimentary particles of the nervous system, and they are the body’s rapid electrochemical information system. Every single neuron receives signals through its branching dendrites, and conducts signals through its axons. Some of our axons are enclosed in a myelin sheath, which enables faster transmission of the signal. If the combined received signals exceed a certain minimum threshold, the neuron “fires” a signal, transmitting an electrical impulse, also known as the action potential, down its axon by way

The structure of neuromuscular junction consists of a neuron and skeletal muscle cell. The motor neurons, which arise from the spinal cord, supply the skeletal muscle fibers. The neuromuscular junction is un-myelin nerve with a bulb shape at the endings that contract the muscle fiber. The schwann cells form a covering over the postsynaptic membrane and nerve membrane of the fiber that is located under the terminal and is categorized as a post-junction folds

Encephalomyelitis Acute disseminated encephalomyelitis is an immune-mediated inflammatory demyelinating condition that affects the white matter of the brain and spinal cord. ADEM also attacks the nerves of the central nervous system and damages their myelin insulation, which destroys the white matter. It is often triggered after the patient has received a viral infection or sometimes exceedingly rarely specific non-routine vaccinations. It affects children more than adults but can affect anyone. More

neurotransmitters, like a circuit in a computer. Then the whole network puts out a response which becomes your outward behavior. Information travels from neuron by way of their axons and dendrites. To make the connection better the axons wrap themselves in myelin through myelination (Scholastic). Kids spend over seven and a half hours a day in front of a screen, that means their brains will develop differently from other generations. The overuse of technology such as Google might cause us to synaptically prune

As a senior this year, I am looking forward to several endeavors, such as leading my team in my last year of cheerleading, participating in a Senior Engineering Design Project, and continuing to volunteer with VSVS, a program that allows Vanderbilt student to teach science lessons in local elementary schools. Moreover, I spent this past summer working on my research at the Vanderbilt Institute of Imaging Science and will continue my projects throughout the school year. I am excitingly close to finishing

Most children in poverty lack basic needs, such as food which can have numerous lifelong effects. The insecurity of food in a child's life has great impacts on his or her ability to learn and develop, which starts a domino effect of not having a proper education, leading to a job that does not make ends meet, continuing the cycle of poverty. Lack of necessities such a food has immediate consequences on the child that takes place during pregnancy, it later effects the behaviour has as the child gets
