This video takes a\u00a0look at the nervous system and all of the things that it is responsible for in the body.\r\n\r\nhttps:\/\/youtu.be\/x4PPZCLnVkA\r\n

Career Connection<\/h2>\r\nThere are a lot of professions that require knowledge of the nervous system, but perhaps the most evident is neurology.\r\n
\r\n

Neurologist<\/h3>\r\nNeurologists are physicians who specialize in disorders of the nervous system. They diagnose and treat disorders such as epilepsy, stroke, dementia, nervous system injuries, Parkinson\u2019s disease, sleep disorders, and multiple sclerosis. Neurologists are medical doctors who have attended college, medical school, and completed three to four years of neurology residency.\r\n\r\nWhen examining a new patient, a neurologist takes a full medical history and performs a complete physical exam. The physical exam contains specific tasks that are used to determine what areas of the brain, spinal cord, or peripheral nervous system may be damaged. For example, to check whether the hypoglossal nerve is functioning correctly, the neurologist will ask the patient to move their tongue in different ways. If the patient does not have full control over tongue movements, then the hypoglossal nerve may be damaged or there may be a lesion in the brainstem where the cell bodies of these neurons reside (or there could be damage to the tongue muscle itself).\r\n\r\nNeurologists have other tools besides a physical exam they can use to diagnose particular problems in the nervous system. If the patient has had a seizure, for example, the neurologist can use electroencephalography (EEG), which involves taping electrodes to the scalp to record brain activity, to try to determine which brain regions are involved in the seizure. In suspected stroke patients, a neurologist can use a computerized tomography (CT) scan, which is a type of X-ray, to look for bleeding in the brain or a possible brain tumor. To treat patients with neurological problems, neurologists can prescribe medications or refer the patient to a neurosurgeon for surgery.\r\n\r\nThis website<\/a> allows you to see the different tests a neurologist might use to see what regions of the nervous system may be damaged in a patient.\r\n\r\n<\/div>\r\n

\r\n\r\nIt is tempting to view different topics as completely separate, but in fact the ideas we cover in this course are often connected to one another. If you don\u2019t retain the vocabulary from module to module, those connections can be missed. As you continue on, remember to come back and review the terms you\u2019ve learned in order to increase your depth of knowledge.\r\n\r\n
