STEM CELL RESEARCH AND THERAPYAND ITS IMPACTS ON SOCIETY Abstract There are several types of stem cells being used in stem cell research and therapy today. They are embryonic‚ adult and induced pluripotent stem cells. Each will be discussed further. This topic has stirred much moral‚ ethical and political debate as whether cells from fetuses should be used in this research. This impacts governmental policies on laws and funding. Another issue that must be analyzed is the

Optic nerve sheath diameter (ONSD) The anatomy of the optic nerve sheath : The intraorbital section of the optic nerve extends from the globe‚ where it inserts medially‚ to the optic canal located in the lesser wing of the sphenoid bone. It is encased by a meningeal sheath consisting of dura mater‚ arachnoid mater and pia mater. Cerebrospinal fluid is contained in the trabeculated subarachnoid space and is continuously and slowly filtered. As a result the optic nerve sheath is in direct

Cells of the body are organized into four fundamental tissues; epithelial‚ connective‚ muscle and nerve. Epithelial tissues line all surfaces of the body: the skin‚ cavities‚ ducts‚ vessels. They are named according to the cell shape on the free surface. Cells of a tissue are held together by the basement membrane and intercellular fibbers. These tissues receive their nutrition by diffusion‚ for they are without blood vessels. Simple squamous epithelium lines all blood and lymphatic vessel‚ including

Recent studies of stem cells have played are very important because they show promise in helping man solve or at least grasp the solution to the diseases that have haunted him since his early days of conscious. The idea of stem cells is kind of a simple idea. This brings us to the first promise‚ not only are stem cells able to be taken from the human body‚ but scientists are now able to grow these cells in labs. The most worried over part is that when obtaining the cells‚ it doesn’t always

SPECIALIZED CELL ANIMAL Sperm cells PLANT Xylem cells are specialised to find a female cell (egg cells) and join with it. They have tails‚ that makes them move in water to find and fertilize the female cell. They can move because they have many mitochondria located between the tail and the head‚ which gives them energy. In the head‚ there is a vacuole filled with acrosome‚ which is a specialized Lysosome that releases enzymes in order for the Sperm Cell to break into the Egg Cell‚ through the

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized

The History of the Roy Adaptation Model The Roy Adaptation Model for Nursing had it’s beginning with Sister Callista Roy entered the masters program in pediatric nursing at the University of California in Los Angeles in 1964. Dorothy E. Johnson‚ Roy’s advisor and seminar faculty‚ was speaking at the time on the need to define the goal of nursing as a way of focusing the development of knowledge for practice. During Roy’s first seminar in pediatric nursing‚ she proposed that the goal of nursing

The Effects of Disrupted Visual Fields on Perception: Perception Adaptation Submitted in Partial Fulfillment of requirements for Psychology 1100E Abstract Kornheiser and Stratton are responsible for much of the modern day understanding of perception and adaptation. The purpose of this experiment was to examine the affects of sensory changes on perception adaptation. In this particular experiment‚ 105 Huron University College students completed a simple task

Being exposed to so many different challenging scenarios I realized my biggest strength or skill would have to be my ability to adapt. In 1st grade I was moved from my neighborhood elementary school which had my family and neighbors to a magnet school that fostered more successful students but was much farther from the security of familiarity‚ which in this case was my neighborhood and my family. In the face of adversity I was able to adapt to my circumstances and succeed. This same ability showed
