Brain Stem Essay - 750 Words

Brain stem is considered to be one of the most primitive parts of the brain that is crucial to human survival. As thoroughly explicated by most scholars and anatomist throughout the centuries, it regulates the most fundamental physiological activities of the human body which are essential for maintaining and sustaining life. This is how each function is utilized in medical practice to define death through different research and experiments. Brain stem regulates alertness, arousal, breathing, blood pressure, digestion, heart rate and other autonomic functions. (Lawrence, 2006) It also contains most of the 12 cranial nerves responsible for sensory and motor functions of the face and special senses, meaning hearing, vision, taste, smell and†¦show more content†¦Net ( 2010), â€Å"For many years the subventricular zone has been suspected to be the origin of specific malignant brain tumors called gliomas, the most deadly type of which is glioblastoma.† (To Function, Brain Stem Cells May Rely on a Specific Molecule, para. 2). Researchers have shown that brain stem cells in the subvetricular zone have been characterized a certain molecule called Protein Tlx. It is a transcription factor that stimulates the activity of various genes as stated by Stem Cell Digest.Net. They used mice during this experiment and when they tested adult mice; they found out that Tlx was expressed solely in its brain stem cell. When the scientists switched off Tlx, they discovered that there were no hidden stem cells in the brain and the neurons stopped or ceased. In reference to Stem Cell Digest.Net; recent studies by teams headed by Professor Gà ¼nter Schutz, and Professor Peter Lichter in Germany at the German Cancer Research Center tested the opposite of the above mentioned experiment. They did about everything the same except theyShow MoreRelatedCan Stem Cells Help Heal Brain Injuries?1066 Words   |  5 Pages Can Stem Cells Help Heal Brain Injuries? Arfa Musaddaq Ms. Meng Sun Biology 30 January 7, 2016 Introduction: Brain injury is a devastating condition associated with trauma, multiple sclerosis or stroke. Successful therapy must be done to overcome this, the associated loss of neurones and supporting glial cells as complex intercellular connections. This scary challenge can be addressed using stem cells because stem cells can regenerate and repair the delicate injured tissue.

The Central Nervous System integrates and coordinates all bodily functions, process all incoming messages and send commands to different body parts. Sending and receiving messages through the spinal cord and the part of the spinal column called a trunkRead MoreThe Nervous System And Controversy1143 Words   |  5 Pagessystem involves researcher investigate the areas of the brain and spinal cord affected by disorders ,as well as the genetic factors, and environment factors involved in order to synthesize an understanding of the nervous system ‘s function (Gilbert, 2002). Construction of the Nervous System and Its Role in Shaping Behaviors There are two main divisions that comprise the nervous system: the central nervous system consisting of the brain and the spinal cord and the peripheral nervous system consistingRead MoreA Congenital Malformation Commonly Affecting Children Born With Spina Bifida869 Words   |  4 PagesSpina Bifida, the Arnold-Chiari malformation, or Chiari Malformation Type II, involves the irregular extension of both the cerebellar tonsils and the brain stem tissue into the opening to the spinal canal – the foramen magnum (NINDS, 2013). Typically, the brain stem and the cerebellum sit above the opening to the spinal canal, where the brain stem houses most of the cranial nerves that supply the body. Providing the control centres for vital bodily functions such as breathing, regulation of the body’sRead MoreEssay Paranoia825 Words   |  4 PagesParanoia If it has been confirmed that brain equals behavior, then why dont we fear our own thought processes? Persons with paranoia disorder are not aware that they are in fear of their own brains, but in some respect fear of oneself and what ones brain can create is exactly what persons with paranoia disorder experience. Everyone experiences small doses and bouts of paranoia on nearly a daily basis, but not everyone exists on its affects. Those with paranoia disorder deal with a constantRead MoreA Red Shifted Variant Of Channelrhodopsin Allows Deep Transcranial Optogenetic Excitation770 Words   |  4 Pages(2014) Focusing Brain Therapeutic Interventions in Space and Time for Parkinson’s disease. Current Biology 24, 898-909. A good understanding of what Parkinson’s disease is, and what brain mechanism are involved is crucial to try to create a treatment. Three different approaches to create high spatiotemporal targeting are presented, one of them being optogenetics. However, by understanding the others, DSB and pharmogenetics, it will become clearer why optogenetics is used in certain brain areas and whyRead MoreThe Most Complex Organ Of The Body1379 Words   |  6 PagesThe brain is the most complex organ in the body. The brain is made up of a complex network of billions of nerve cells called neurons, as well as other kinds of cells, all protected by the bones of the skull. Every human on Earth uses it every single day, even when you are sleeping the brain is not sleeping, but sending signals all over your body to keep you breathing and alive and allow you to dream.

Adding to the controversy, the idea of a higher being most namely that of God or some alternative deity, modifies the idea of reality. My personal belief centers on the monism standpoint, with there being only the body and the body creating the mind – the two are not separate, and the nature of self is born from the different brain configurations and synapse formation.
