Myelin

The reason for the increase of microglia cells can be due to the neuronal dysfunction, or that microglia operate as the mediators of the disorder or both (12, 13). The main function of oligodendroglia is the production and maintenance of myelin in the CNS. It also express muscarinic acetylcholine subtypes (14). The last group of glia cells, the astrocytes has numerous functions in the CNS. An important function is the role in synaptic transmission and information processing (15, 16). In…

Marijuana also affects the physical aspects of the human body. Marijuana smoke cause respiratory problems, increased coughing and production of phlegm and acute chest illnesses like bronchitis and lung infection. Marijuana also increases heart rate from 20% to 100% within a short period of smoking. Marijuana smoke is made up of toxic chemicals like ammonia and hydrogen cyanide that may irritate the bronchial passages and lungs. Marijuana would affect the respiratory system. The drug would also…

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide, with approximately 2 million reported TBI events in the US annually. The pathology of TBI is a highly complex process with both initial mechanical injury and delayed mechanisms. Primary injuries directly damage the neurons, axons, dendrites, glia and blood vessels in a focal, multifocal, or diffuse pattern. Primary injuries initiate a secondary, dynamic series of complex cellular, inflammatory, mitochondrial,…

How The Natural Human Learning Process Affects Us The Natural Human Learning Process is very important in our everyday lives; everything we learn during our day is affected by the Natural Human Learning Process. According to Rita Smilkstein there are six steps to the Natural Human Learning Process which affect our learned skills. Our learned skills are stored in our neurons which are easiest to remember if you think of it as a tree in our dendrites. What causes our dendrites to grow is the…

Playgrounds can be found all over neighborhoods, towns, and schools and provide an excellent way for children in early and middle childhood to develop and work on physical growth in a safe way. Children go through a sensitive period which is a point in development when organisms are susceptible to stimuli in their environments (Feldman, 2017). Gross and fine motor skills are able to be developed further through play in an environment such as parks and are different for children in the early and…

an iron sufficient mom whose child was deprived of iron. They tested motor behavior, sensory processing, social and cognitive skills of the monkey’s offspring They then developed 3 hypotheses about iron affecting dopamine (iron dependent enzyme), myelin (glial have a high need for iron), and hippocampal development. They conducted some brain and behavior assays and an impulsivity test and found that their dopamine hypothesis was not supported. Hippocampal development wasn’t brought up again…

can hinder the brain development of children. For instance, on Listland, James Atwater states, “As outlined by neurologist Larry Robbins, children’s brain structure is different to those of adults, lacking both protective covering of nerve cells (myelin) and the foundational support of strong neck muscles.” This indicates that because of the lack of brain development in children, it is much safer to delay playing tackle football until the brain is fully…

MS is a disease that damages the myelin sheath the covers neurons affecting the overall communication of the nervous system. Since similar damage occurs in leukoencephalopathy with neuroaxonal spheroids it easy to understand why symptoms might mimic those of MS. The disruption of communication…

brain, causes severe nerve transmission to be incomplete, there for the body isn’t able to perform properly. The slowing of brain process will cause it to eventually fail and unable to work. The brain disorder of buildup, causes the deterioration of myelin. This layer is a protective coating that surround the brains neurons. Without that barrier, the neurons can’t tell the nerve cells how to operate. Meaning that the loss of activity within the body will seem to deplete leading to serious…

are present along with Na+ and K+ channels, along the length of axon. If a cell is unmyelinated, it can pump Na+ back out into the ECF, causing a loss of conduction and decreasing the frequency of axon potentials. In myelinated cells, however, the myelin blocks these pumps from pumping Na+ out of the cell, and maintains concentrations. If Na/K ATPases are only able to pump Na+ ions out at the nodes of Ranvier, leakage will only occur there. 8. List the types of synapses • Electrical- Very…
