Myelin

the lower spine.6 One to two tablespoons of the fluid is withdrawn through the syringe. People with MS usually Their CSF contains a specific group of proteins called oligoclonal bands, and there are also proteins that are the breakdown products of myelin.6 These results show an abnormal immune response within the central nervous system. This means that the body is generating an immune response against itself. The abnormal immune response in CSF is found in other diseases, so this test is not…

1. There are 3 types of neurons. Motor, sensory, and Interneurons. The main parts of the neuron are dendrites, the soma, the axon, the axon terminal, the synapse, and the myelin sheath. The dendrites are branch like bushy extensions that receive the information and conduct impulses towards the cell body. The soma, or cell body, makes sense of the information and works It out. It also triggers the action potential and all or nothing response. The axon is a neuron’s extension that sends messages…

Concussions In Sports Concussions are the most popular type of head trauma in children and adults, yet it has only been within the last few years that the understanding of what concussions are and how easily they can occur in sports and other accidents, such as a fall or a car crash, has come to the attention of coaches, parents, and medical professionals.

1.) Susan is postmenopausal, so there is a higher risk for osteoporosis. She is also not on hormone replacement therapy. Estrogen helps preserve bone mass by inhibiting bone dissolving action of the osteoclast. However, Susan is also active and exercises regularly, so she is less likely to have osteoporosis. Other factors such as bone cancer could have led to the weakening of her bones. 2.) If Susan had bone cancer, the CT scan would reveal the presence of a tumor. The densitometry scan would…

activation of the complement system and release of its components is well-known to trigger inflammatory response in many body organs, including the brain itself, experimental evidence reveals a potential role of some of these molecules in enhancing myelin and oligodendrocytes function, such as terminal C5b-9 complexes (11). Other complement proteins were also proven to maintain a neuroprotective function through supporting development and maturation of glia and neurons, and preventing CNS…

In the science field, a lot of the time research can be portrayed differently in popular press articles, for example newspaper or magazine articles, compared to the scientific article published from a peer-reviewed journal. Sometimes newspaper or magazine articles can forget or exaggerate certain results. This is why it is always important to read not only the popular press literature but also to read the material from which the popular press got its information. The journal article I chose to…

Diseases of the Cell Assignment: Heart-Hand syndrome & X-linked Adrenoleukodystrophy Heart-Hand Syndrome is also known as Holt-Oram Syndrome, where individuals are born with skeletal abnormalities of hand and arms (upper limbs) and heart problems due to the mutation of HOS1into the TBX gene. TBX gene plays a role in controlling growth of bone in the hand and arm. Also, TBX is present in chromosome 12. The symptoms include: missing thumbs, long thumb that looks a like a finger, partial or…

correction of hyponatremia (defined as < 135 mEq/L).1 Current guidelines1,2,3 dictate a slow correction of sodium, generally not exceeding 8-10 mEq/24 hrs to prevent CPM.1 CPM is a non-inflammatory demyelinating disease characterized by the loss of myelin in the base of the pons and carries a poor prognosis, often times resulting in death. We present a case in which an elderly gentleman was admitted for generalized weakness, and was found to have moderate hyponatremia. Despite a gentle…
