Spina bifida is a type of defect at birth called a neural tube defect. It occurs when the bones of the spine (vertebrae) do not form correctly around part of the baby's spinal cord, during the first month of pregnancy. This disease usually affects the brain and spinal cord because of incomplete development. There is no scientific explanation of what causes spina bifida, but there are some factors that can result in the disease. Folic acid deficiency, combination of genetic and environmental risk…

Contemporary Biology Article Assignment To Mend a Birth Defect, Surgeons Operate on the Patient Within the Patient Since the 1990s, Spina Bifida has been repaired by Doctors fetal surgery to lessen the degree of disability. Spina Bifida causes children to not be able to walk, as well as fluid buildup in the brain. It affects 1.500 to 2,000 fetuses a year. The backbone and spinal cord never develop completely or properly causing a gap in the fetus’s lower back exposing bone and nerves. In…

on the nervous system, structures of the brain and their functions, genetics and behavior, and more about how the brain works. The nervous system is talked about in this chapter as “the body’s electrochemical communication circuitry”. Within this subtopic, it talks about pathways and divisions in the nervous system. It also talks about neurons in the nervous system, which are the things that handle the information-processing function. Glial cells are the cells found in the nervous system, and…

the drug complicated. It is hard to predict how many users of the drug there will be because it is rare and finding out if insurance companies will approve paying for the treatment is difficult as well. Beyond this, the United States healthcare system is extremely complex which makes selling the product even harder. Data as recent as last week shows that sales of Spinraza is not growing at the rate that Biogen analysts had predicted. The analysts predicted that sales would be about $381.55…

A crippling infectious disease that’s produced by a virus, named polio (poliomyelitis), originally named “infantile paralysis” or “the crippler,” because of its ability to damage nerve cells and control muscles permanently, made its primary epidemic in Canada in1910 (The Story of Polio). This illness can affect humans of any age, however kids who are below the age of five are at higher risk than others. This disease first became known when a young girl had been taken to a hospital in Hamilton,…

5 Spinal Bifida 1. Definition: • A birth defect that affects the neural tube. • The neural tube is the embryonic structure that ends up developing into the brain, spinal cord, and the tissue that surrounds and encloses them. In babies diagnosed with spinal bifida, the neural tube does not form correctly and is left open, causing defects. 2. What are the causes/risk factors: • Experts have not figured out what the exact cause of this disorder. Most think that the link is genetic or…

(The nervous system Louisa Idzal) The nervous system is all connected because it’s a web of nerve cells and fibers that all send nerve impulses throughout and between body parts. The nervous system is really important because it’s in charge of sending messages to the spinal cord and brain to and from all parts of the body. Main organs of the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the…

According to Dr.Gottfried Schlaug, associate professor of neurology and director of the Music and Neuroimaging Laboratory at Beth Israel Deaconess Medical Center and Harvard Medical School, “Neuroplasticity is the term for the brain’s ability to pave new pathways around damaged areas,”(Mossie). Due to this incredible ability that the brain has, Congresswoman Gabby Giffords relearned to talk within ten months of having a bullet wound to the head. Giffords suffered from aphasia- the inability to…

replicates and spreads in throat and gastrointestinal tract. Then potentially gets absorbed and disbursed out into the blood and to the lymphatic system. Incubation period ranges from seven to fourteen days. So about a week or two. Which it can affect the CNS cells, then it will replicate motor neurons in the brain stem. Furthermore, leading to damage in nervous cells and destruction…

One of the most common types of Spina tumors is the Intramedullary Tumor. Spinal Cord Tumors are abnormal mass of cells that grow rapidly, but do not have any real physiological function and are found in and around spinal cord. Most of these spinal tumors are Astrocytomas and Ependymomas. Astrocytomas: Glial cell tumors that are derived from connective tissue cells called astrocytes. Theses cells can be found anywhere in the brain or spinal cord. Ependymomas: Also, glial cell tumors.…
