Identify if the statement is True or False. If the statement is false, identify what is incorrect and correct it.  Cellular adaptation often refer to reversible changes in size, number, phenotype or appearance, metabolic activity or functions of cells in response to adverse environmental conditions or internal bodily stresses Pathologic Hyperplasia refers to an abnormal increase in the number of cells, which are in a normal component of that tissue and are arranged in a normal fashion with subsequent enlargement of the affected part.

. The character (s) is fictional. The description of the disease/disorder is based on information from Mulvihill, M.L.; Zelman, M.; Holdaway, P.; Tompary, E.; Turchany, J. (2000) Human Diseases. A Systemic Approach. Prentice Hall, New Jersey.  Nerve Tissue Diseases: Tetanus1 While visiting his aunt that lives on a horse farm, Milo fell and injured his knee. His aunt cleaned the wound and covered the area with bandage. A week later, Milo was taken to the hospital because he could not open his jaws or swallow food. The doctor explained that a bacteria called tetanus bacillus that lives in animals’ intestines had entered the wound on Milo’s knee. The bacterium produced a strong toxin that stimulated Milo’s motor nerves innervating his jaws causing severe spasm of the muscles. Help Milo understand his condition by completing the following tasks: A. Draw and label the parts of amotor neuron.  B.  Draw a diagramto explain how myelin sheaths speed up the conductionof impulses through the…
