CELL SIGNALING AND CELL TRANSDUCTION INTRODUCTION: In this lecture, we will study about cell signaling and signal transduction. Each cell in a multicellular animal is bombarded with chemical signals that are made by other cells and this is how communication occurs at cells level by different signaling molecule. Signals that regulate cell metabolism, alter or maintain its differentiated state, determine whether it should divide, and dictate whether it will live or die. The word “signals” in…
Systems thinking (ST) is a concept to understand how a complex system (e.g. health management) functions as a whole by examining how the components (subsystems) of the entire system are connected and interact dynamically instead of as individual stakeholders. Historically, ST was developed and used by various disciplines in the twentieth century to transfer methods across disciplines known as interdisciplinary (Peters, 2014). Multiple disciplines can collaborate about methods and conceptual…
Our body as we know it is a complex system as well as the class room environment where skill learning takes place. This is due to the multiple moving parts inside the systems. Complex systems also have other facets to them such as having multiple levels to them, having attractor states to do things in certain ways, having self-emergent discovery, affordances constraints, as well as things working together independently but together as a whole. Our bodies being complex as well as the class room…
Since it is the first time she has her own classes, it is sometimes quite stressful for her even if she likes her job. The past few years, she reported numerous neurological complaints which came and went affecting several different neurological systems. She experienced stumbling gait preceded by heat intolerance which led to a tendency to fall. She also experienced a periodically change in her visual acuity. Two months ago she had a real stressful time: preparing the upcoming exams for her…
Helen Keller essay By:Tiarra Sorey It is often said that the human body system is very complex, all of the many different structures has its normality just as much as it has its disorders. The eye is the organ of vision, the process in which vision is produced can be affected by things such as increased pressure, exposure, or just simply age. When this process is affected eye disorders such as glaucoma, cataracts, myopia, astigmatism, and many more, come into place. The ear…
Introduction Systems thinking, as defined by today’s scholars, has been around for decades and continues to grow as researchers turn to the past, present, and future to gain a better understanding. In fact, concepts found in systems thinking go back to the time of Aristotle (Mele, Pels, & Polses, 2010; Ing, 2013). This method points out how systems have no ends, are all interconnected, and that it is impossible to completely comprehend anything (Senge, 2014). Since humans tend to want to…
Many wonder if vaccinations are really necessary or if they are even safe. Vaccinations are what allow people the American Dream because it saves lives which enables an individual to achieve happiness. While vaccinations help prevent diseases in America, some believe the potential harmful effects carry too high a risk. Limiting vaccinations would cause an outbreak in diseases because vaccines prevent the disease from forming. Vaccinations have lowered the risk of getting a disease, but the…
My History As A Writer Throughout my lifetime I have come to love and absolutely hate writing. The reasoning of the assignment or topic has a lot to do with my affinity and disgust. Although learning new things, like writing, was something that I loved doing in elementary school, that all changed when it was daily implemented. As an art form I recently come to love writing down my thoughts, ideas, opinions and stories. A struggle for me while attempting to write an essay or report is grammar.…
Introduction “More delicate than the historians’ are the map-makers’ colors (Bishop 1).” Gerrymandering is when a district’s boundaries are redrawn to benefit particular political parties’ agendas (Ingraham 1). Gerrymandering promotes the statistical concept of Simpson’s paradox. Simpson’s paradox describes the phenomenon of having a higher percentage of votes; however not having more votes numerically (Simpson’s 1). Gerrymandering is similar because it also gives the possibility of winning the…
that may come from them being dysfunctional, as well as how scientists use them in medicine. Unlike a normal cell, stem cells have several possible, special tasks assigned to them at their time of creation, making them useful as an internal repair system for several different parts of the body, including muscles themselves. Stem cells, also called somatic cells or vegetative cells, are remarkable for the field of medicine because they are known to be some of the basic building blocks of…
