Gap junction

(myelinated). The myelin sheath is an insulator that helps increase the velocity at which an action potential is propagated along an axon. The myelin sheath is commonly made of a type of glial cell known as the Schwann cell. The Schwann cells have small gaps between them termed nodes of Ranvier. Kendal and colleagues state that the action potential moves faster along the internode (myelin sheath) because of the low capacitance of the myelin sheath. Its speed decreases as it reaches a node of…

Carolyn Wehner CEE 1440 Water Resources Engineering Take-Home Final Exam Due: 12/14/16 Introduction: With changing climates, ice caps melting more rapidly therefore causing the water levels of the world to rise rapidly. With this increase of fluid water on the earth water resources engineers are concerned how the excess water will affect infrastructure pertaining to water designs such as dams and reservoirs. Also future engineering designs will have to consider the change in water levels and…

Cells Interacting: Astrocytoma in its cancerous form is a situation in which a malignant tumor starts in Astrocyte cells, which have the purpose of protecting nerve cells. As the tumor grows invasively into these cells, it presses on the nerve cells and other parts of the brain. Cancerous astrocytoma will grow very quickly, spreading into other sections of brain tissue. As it does this, it will start to push on the brain itself and stop it from functioning properly. …. Function: The…

taking care of her children, she decides to present a “Man’s Excuse” instead of telling the truth. She tells her male senior manager an excuse he would be content with and that he would be able to relate to: “You should have seen the mess at Dalston Junction… some maniac in a white van. Traffic lights out of sync. Unbelievable. Must have been stuck there—oh, twenty minutes” (Pearson 16). Her excuse works as her manager accepts it and moves on with his day. Another example relates to Maushart’s…

their competitors women in computing is a great resource. Hence maybe why google is starting their initiative. The article I read was titled “The Trouble with ‘women in computing’: a critical examination of the deployment of research on the gender gap in computer science”. As the title describes that article establishes a known issue but doesn’t offer a solution or remedy to the problem we face. Instead it just present facts, such as trends about women in computing. One trend they established is…

Overview of The Myocyte The myocyte is composed of various protein filaments that comprise the contractile apparatus of the cardiac cell. Myofibrils, a collection of individual sarcomeres, enable contraction and relaxation of the myocyte. The sarcomere is the chief contractile unit of the cell. It is made up of two main proteins, myosin (thick filament) and actin (thin filament), as well as two regulatory proteins, tropomyosin and troponin. In order for the myocyte to contract and shorten it…

PATH2201 Processes in Disease Media Assignment – Can Probiotics Aid in the Treatment of Coeliac Disease? Elissa Jennifer Watt (z3463000) 21/09/14 Tutor: Melanie Walker Introduction Advances in medical diagnosis and screening have revealed that coeliac disease (CD) is a major health issue across the world, affecting all ages. In Australia, the rate of CD was previously estimated to be around 0.4% (Hovell, et al., 2001). More recent estimates suggest that around 1.2% in men and 1.9% in…

hinge of the Antwerp–Meuse defensive line that the Germans were now preparing. The British were to attack the Hindenburg Line between Cambrai and Saint-Quentin on September 27 and to try to reach the key rail junction of Maubeuge, so as to threaten the Germans’ line of retreat through the Liège gap. The Belgians, with Allied support, were to begin a drive from Ypres toward Ghent on September…

Genetic Engineering in Humans: When Should We Stop? Societies debate against each other if genetic engineering in humans should be used in humans. What using this type of research and technology in humans means, modifying the type of organism(in this case humans) by manipulating the genes to standards society thinks is the best. Scientists think humans should use genetic engineering towards curing diseases while other scientists think humans should use this new technology towards creating new…

The light touch of the setter’s hands on the ball grabs my attention. As the ball comes flying toward the hitter I can see their body is aimed toward me. I focus on watching the ball, attempting to get as much information as I can by watching its arced path. I can see that the ball was set inside, and my eyes integrate this information causing my body moves to the left without my direct mental input. Automatically my heartbeat becomes faster, as I throw my hands together to pass the volleyball.…
