Textbook Question
Chapter 9, Problem 1AC
Most nerve cells in the adult human central nervous system, as well as heart muscle cells, do not divide. In contrast, cells lining the inside of the small intestine divide frequently. Discuss this difference in terms of why damage to the nervous system and heart muscle (for example, damage caused by a stroke or heart attack) is so dangerous.

Reports in the media about stem cells usually state that they “turn into any kind of cell in the body.” Explain why this statement is only partially correct, including a description of how a stem cell maintains the population of stem cells.
Release of lysosomal enzymes from white blood cells during a local immune attack can contribute to the symptoms of inflammation. Suppose to alleviate inflammation, you develop a drug that destroys all lysosomes. Would this drug have negative side effects? Why or why not? Answer this question in 1-2 sentences.

- Shock (failure of the circulatory system) is an abnormal condition in which blood flow is inadequate. The most common causes of shock are massive blood loss and obstruction of blood flow. As a result of shock, there is a failure to provide cells with oxygen and nutrients. In this circumstance, cells swell and lysosomal membranes rupture, among other effects. Describe how energy is generated during shock and why cell structure becomes destabilized.arrow_forwardRetinoblastoma is a rare cancer in which tumors developin the retina of the eye.
