  • Three Types Of Glial Cells And Neurons

    Neurons are not the only cells that occupied the central nervous system (CNS). In fact, neurons are outnumbered by supportive non-excitable cells, collectively called neuroglia (a.k.a. glia). The term glia was coined by Rudolph Virchow in 1859 to indicate the “connective tissue” surrounding the neurons (glia came from Greek meaning glue). However, the combination of the activities of glial cells and neurons is crucial for brain functions (Steward 2000). There are three types of glial cells in the CNS that can be distinguished by size and embryonic origin: oligodendrocytes (a.k.a. oligodendroglia), astrocytes (a.k.a. astroglia) and microglia (Fig. 1.1). In the peripheral nervous system (PNS) Schwann cells can be found. Astrocytes and oligodendrocytes…

  • Glial Cell Essay

    Glial Cells are supporting cells in the nervous system (central nervous system [CNS] and peripheral nervous system [PNS]) which aid in the efficiency of neural operations in the nervous system, (Carlson, 2013). Carlson (2013, p.36) indicates the general functions of the glial cells as: keeping neurons in place; supplying neurons with nutrients and the chemicals needed to communicate with each other; protecting neurons from each other to promote coherent messages; and “destroying and removing the…

  • Animal Cell Structure

    For the purpose of this report we will be focusing mainly on the base level of cells, and those of an animal. Within all organisms we find cells, they form the life blood of their being. Cells contain the blue prints for all life forms known as D.N.A. Cellular structure While complex, cellular structures can also be relatively simplistic in design. Each component of the cell plays a vital role, working together in harmony to provide life. Initially we must look at the cell membrane. The cell…

  • Mitosis And Meiosis Case Study

    1. What is the difference between mitosis and meiosis? Define each term, and then explain how each process contributes differently to the conception and growth of a zygote. The two ways cell division can occur are through mitosis and meiosis. In mitosis, a cell produces two clones of itself, each with the same number of chromosomes. In meiosis, a cell will produce four cells called gametes through the process of spermatogenesis and oogenesis. Gametes are most commonly known as sperm cells in…

  • Allometric Growth

    brain, thymus (lymphoid tissue), reproductive system, and absolute growth curve of the whole body are the main things to be focused on allometric growth of human (Refer to Figure 1, Appendix 1). From the stage of newborn until 5 years old, brain will grow and develop with its highest rate and at the age of 2 years old will reach about 80% of the adult size. 250,000 neurons will be added every minute during the brain development since a baby is born. At this stage, young children’s brain will be…

  • Analysis Of Your Inner Fish By Neil Shubin

    Neil Shubin’s documentary series “Your Inner Fish” explores the relationship between humans and all other living organisms. Shubin delves into human evolution to uncover similarities that connect humans with the world around them. The anatomist studies fossils, embryos, and various other parts to compare humans to fish, reptiles, and primates. Shubin challenges the common beliefs about evolution by recognizing the corresponding features between humans and seemingly unrelated organisms. The…

  • Human Cloning: The Characteristics Of Humans?

    the chromosomes. Clones come from a scientific process called the somatic cell nuclear transfer or SCNT. During this process, scientists remove the chromosomes from the egg cell and replace them with the nucleus of a somatic cell which contains two sets of chromosomes. Since the nucleus of the somatic cell comes from a human who already displays genetic variation from their mother and father, the clone will receive both of their sets of chromosomes from one cell, and not from both the egg and…

  • Animal Testing In Medicine

    studies that can contradict predetermined concepts. Therefore, researchers can be studying a peculiarity of some specie that can be resulted by many different factors. Trying to apply this new discovery in humans can be catastrophic as these new concepts cannot be applicable to human beings. For example in 1960’s, experimentation on animals showed that the tobacco did not cause lung cancer, although it caused some minor issues. This research was used for years as an argument to delay the…

  • Animal Cell Process Lab Report

    headquarters, and with that our micro-V96 craft was propelled towards the cell membrane for the first leg of our journey to investigate the process of Protein Synthesis in a eukaryotic animal cell. The cell membrane is a delicate wall of phospholipid molecules, consisting of hydrophilic heads and hydrophobic tails that swayed and looked like a mosaic. Our craft could not enter the cell directly through the semi-permeable membrane as it consisted of a negatively charged polysaccharide which was…

  • Persuasive Essay On Gm Foods

    they are developed because there is some perceived advantage either for the producer or consumer of these foods. This is meant to translate into a product with a lower price, greater benefit in terms of durability or nutritional value. How can DNA be moved from one organism to another? • Find an organism with the desired trait • Isolate the gene sequence that codes for the desired trait • Insert the gene sequence into the genome of the plant cell • Allow the genetically altered cell to grow…
