Problem 13
Although cells have differences that reflect their special functions in the body, what functional abilities do all cells exhibit?
Problem 14
Describe the four structural components of the plasma membrane and the function of each.
Problem 15
Name the cellular organelles, and explain the function of each.
Problem 17
Describe the general characteristics of epithelial tissue. List the most important functions of epithelial tissues, and give examples of each.
Problem 18
What are the general structural characteristics of connective tissues? What are the functions of connective tissues? How are their functions reflected in their structures?
Problem 19
Tell where each of the three types of muscle tissue would be found in the body. What is meant by the statement, 'Smooth muscles are involuntary in action'?
Problem 20
Contrast cytokinesis, interphase, and mitosis.
Problem 21
Hydrocortisone is an anti-inflammatory drug that stabilizes lysosomal membranes. Explain how this effect reduces cell damage and inflammation.
Problem 22
Michael had a nervous habit of chewing on the inner lining of his lip with his front teeth. The lip grew thicker and thicker from years of continual irritation. Michael's dentist noticed his greatly thickened lip, then told him to have it checked to see if the thickening was a tumor. A biopsy revealed hyperplasia, but no evidence of neoplasia. What do these terms mean? Did Michael have cancer of the mouth?
Problem 23
Think carefully about the chemistry of the plasma membrane, and then answer this question: Why is minor damage to the membrane usually not a problem?
Problem 24
Jeanie was taken to the ER for heat stroke and dehydration. Should she be given IV fluids that are hypertonic, isotonic, or hypotonic to cytosol? Explain your answer.
