Traumatic brain injuries: long term effects of damaged neuron and glial cells
Concussions due to head or neck injuries are common in athletics, in some instances these type of injuries can be misdiagnosed as post-traumatic stress syndrome, or PTSD in military personnel, due to the similarity of its symptoms. For the most part, many individuals’ means of damaging their cell to cell communication pathways, are due to common accidents. Research shows that damage to neurons, specifically glial cells could possibly be related to the long term effects of traumatic brain injuries or TBI, among other degenerative diseases. Most individuals with mild injuries recover without incident, however a subgroup of people develop persistent post-concussive symptoms which often include headaches. Such post-traumatic headaches vary in proliferation and may progress to become chronic and in some cases debilitating. Leading some individuals to the take their own lives to relieve their symptoms. There is little known of the pathogenesis of post-traumatic headaches, nevertheless shared pathophysiology with that of the brain injury is suspected.
By first visualizing the injury at the molecular level, one can begin to understand how a shocking change of environment in these highly functional cells could likely result in prolonged side effects associated with brain injuries. According to Reece (2014), the brain consists of many neurons, which are supported and outnumbered by glial cells. Neurons carry out integration from the central nervous system or CNS, meanwhile those relaying information in and out of the CNS form the peripheral nervous system PNS. Some of the functions of glial cells include, nourishing neurons, insulating the axons, the signaling ...

...pg.1). According to Schultz and colleagues (2015) sodium selenate is a pharmacological compound that activates the protein phosphatase of PP2A/PR55, which decreases hyper phosphorylated tau, may be a novel therapeutic approach to improve the outcome following TBI (introduction). Another possibility for treatment could be a pioneering method called, low intensity focused ultrasound pulsation which was recently used to reactivate the brain of a comatose patient.
Based on the research conducted I can conclude that brain injuries happen at the cellular level, from there a series of cascading events lead to the degeneration of neurons, partially due to the damage and immune response of glial cells following trauma. However, promising techniques to treat brain injuries and stop the degenerative process gives light to people who often suffer from these invisible injuries.

Essay about Mullelr and Glial Cells

- ... It was hypothesized that the endfoot has the biggest impact on the flow of ions across the membrane, and therefore the cell’s resistance and conductance. So, the resistance of the cell was once again measured, but this time with the endfoot removed from the cell. It was expected that if the endfoot of the Muller cell was the region that had the biggest impact on resistance, with the endfoot removed the resistance of the cell would increase. Scientists also decided to cut a part of the cell above the endfoot, without removing the endfoot....   [tags: Brain, Endfoot, Cells]

The Process Of Memorization Starts At Birth With The Development Of Cells

- The process of memorization starts at birth with the development of cells and extends throughout the lifetime through the effects of life experiences and stimulants. Like the rest of the body, the brain is made up of cells. These brain cells are different, more specialized cells. (Sprenger 1). Two major brain cells are the neurons- the nerve cells- and the glial cells which work as the ‘glue’ of the neurons. At birth, the brain contains approximately 100 billion neurons. Although that number remains constant over time, these cells can lose their function if not exercised properly in a process called “neutral pruning”....   [tags: Neuron, Nervous system, Glial cell, Axon]

The Psychological Effects Of Injuries On Athletes Essay

- Injuries are part of an athlete’s life from the time they decide to train. An athlete is aware of the risks in order to be perform and be the best at what they; however, they cannot afford to think they will be injured. They must adopt a mindset that they are untouchable and the best in order to perform and train and peak efficiency. When an injury is sustained however, the effects are disastrous to an athlete not only physically but mentally. An athlete’s mind is the most important thing to them arguably, because without the will power and determination channeled from their mind they would be unable to perform....   [tags: Psychology, Thought, Mind, Cognition]

Analysis and Description of Photovoltaic Cells Essay

- Photovoltaic cells are found everywhere today: your home, work buildings, schools, and more. There are two types of Photovoltaic Cells: Organic and Inorganic. The type of cell that are most often found and used are inorganic cells. Inorganic cells are known to produce much more energy than organic cells. Although the main element used in these inorganic cells is Silicon, there are many more elements that are used in inorganic photovoltaic cells. There is monocrystalline, polycrystalline, amorphous, and microcrystalline Si, the III-V compounds and alloys, CdTe, and the chalcopyrite compound, copper indium gallium diselenide (CIGS)....   [tags: inorganic cells, chalcopyrite compound]

Functions of Plasmodesmata on Plant Cells Essay

- Introduction Cells communicate by transferring molecules from one to another. When a molecule is transferred it creates a reaction which then causes an effect. Within multicellular organisms there is cell-to-cell communication. Direct communication between cells can occur in two ways. One way is cell-cell recognition via interaction between surface proteins. When there is contact between cell surfaces, the proteins on the surface of the cell interact and create a signal. The other way is through cell junctions between adjacent cells....   [tags: molecules, cells, plasma membrane]
