Central nervous system

Abstract Background: Hydrocephalus is an abnormal CSF collection in brain cavities, within the cerebral ventricles caused by a blockage in the drainage or insufficient absorption of the fluid [1]. It is categorized either congenital or acquired [1]. Hydrocephalus can be diagnosed by detailed history, physical examination and radiological examination [1]. MRI is considered the method of choice because It allows us to evaluate various parts of the brain and certain associated conditions that may…

A. THE NERVOUS SYSTEM 1. What are the central and peripheral nervous systems? What structures are part of each? The central nervous system is made up of two parts, the brain, and the spinal cord. The peripheral nervous system is made up of two parts as well, the somatic nervous system and the autonomic nervous system. 2. What are Neurons? Describe the key parts of Neurons, including: Dendrites, Myelin, Axons, and Synapse. To keep it simple, a neuron is a nerve cell. Most neurons are very…

most common form of this condition. Type 1 Gaucher’s disease doesn’t really affect the brain or the spinal cord (central nervous system) that’s why it’s also called non-neuropathic. Type 2 Gaucher’s disease is neuropathic it affects the central nervous system. This disease causes life threating medical problems in the start of nativity. Type 3 Gaucher’s disease also affects the nervous…

In this episode of The Nature of Things, multiple techniques are explained by Dr. Norman Doidge, that help to improve the function of brain; allowing for better injury recovery. This study includes treatments for, severe causes of autism, traumatic brain injury recovery, Parkinson’s, and a girl missing one-third of her cerebellum. Specifically, these treatments include light treatment, sound treatment, using other brain regions to complete everyday tasks, and passing electrical currents through…

Creutzfeldt – Jakob disease known as (CJD) is a rare neurodegenerative disease that breaks down the brain only infecting about one million people worldwide. CJD belongs to a family of human animal diseases known as transmissible spongiform encephalopathies (TSEs). Infected brains become filled with holes looking like sponges. There are also other TSEs Kuru, fatal familial, insomnia FFI, and Gerstmann-Staussler-Scheinker disease (GSS). CJD is caused by glycoprotein called a prion. Prion…

Polio is a viral sickness that is contagious, and it is caused by one of the polioviruses. In most cases, polio is mild but some do have paralytic polio. Polio has likely been around for thousands of years. There is an Egyptian carving dating back to 1400 B.C., depicting of a boy with a leg deformity like the one someone with Polio would have. Polio was low level until the 1900s. Polio started being epidemic when other illness like typhoid and tuberculous started declining. Scientist believe…

According to Centers for Disease Control and Prevention (CDC), spina bifida is a condition that is obvious at birth and disturbs the spine (“Spina Bifida,” 2017). It is a type of neural tube defect. “Spina bifida can happen anywhere along the spine if the neural tube does not close all the way.” If/when the neural tube does not close all of the way, the backbone that protects the spina cord does not shape and close as it should. When this happens, it can lead to damage to the nerves and spinal…

Falling at number eight on the thirteen steps of complexity are organ systems. These organ systems are extremely important in the makeup of organisms. Two very important organ systems are the muscular and nervous systems. Both have separate functions and organs and also have their own fair share of problems. The muscular system composes of the tissues and organs that are used to exert a force, whether under voluntary or involuntary control. Muscles are composed of long, slender cells called…

different processes to return the body back to normal and stable. The body is complex with multiple organ systems, but this essay will explain how the different parts of the nervous system and its relationship with other organ systems maintain homeostasis. The nervous system has three parts that work together, the central nervous system (CNS), peripheral nervous system (PNS), and autonomic nervous system (ANS), which are further divided and each division…

Micheal Merzenich was one of the world leading researcher on brain plasticity and famous for his innovation and practical inventions in Neuroplasticity. His works mostly involve brain mapping, where brain is trained to think and process information differently. He believed doing the brain exercise is similar to taking drugs to treat brain diseases. He cured some disorder that once thought incurable. He is the first one to design the cochlear implant that allow deaf children to hear. He designed…
