74) An older friend of yours who has been a dedicated jogger for many years has been having mild knee pain recently when jogging longer distances. He tells you his doctor recommended better-cushioned running shoes. He wonders why better shoes on his feet will help his knees. Using the material you learned about the skeletal system, what can you say to help your friend understand his doctor's recommendation?
Answer: The knee joint has shock-absorbing cartilage that can wear with age (part of the story of osteoarthritis). Anything that helps reduce impact will help prevent further damage.

75) An auto mechanic friend expresses interest in changing his career to nursing. He sees that anatomy and physiology is one of the courses he needs to take. He asks you what such a course would be like. You decide to explain it to him by comparing the human body to a car. How would you explain the course to him?
Answer: Anatomy is the study of the structure of the body, so it would be similar to learning the parts of a car and how they fit together. Being able to assemble (and disassemble without damaging) car parts such as a transmission or engine would be anatomy. Dissection of specimens used in anatomy would be similar to that auto part disassembly process he knows so well. However, physiology would be the study of how things function, so the fact that your friend knows how the engine and transmission work to move a car would be similar to physiology. He needs to know how those automobile parts work so that he can figure out what's wrong and how to fix the parts when they are malfunctioning–just as a medical professional must do when body parts aren't working properly.
Topic: Section 26.1
Skill: Synthesis/Evaluation
76) What is the evolutionary significance of tissues, organs, and organ systems in animals?
Answer: Tissues allowed a specialization or division of labor amongst the growing number of cells in the animals. Because a single cell no longer had to do all life functions itself and instead could cooperate with neighbors, larger size was also a by-product of specialization. As organisms evolved larger body size, they had more cells that were further from the surface where nutrients and wastes could be exchanged. Systems such as the cardiovascular and respiratory systems developed to bring nutrients to these deeper cells and remove wastes from them. Large, complex animals would not be possible without such specialization.

77) A biology classmate seems confused by something he read at the professor's website about calcium imbalances and neurotoxins interfering with proper functioning of the muscular system–even to the point of causing death by suffocation. He states the professor probably goofed up and meant the skeletal, nervous, and respiratory systems were adversely affected. Defend your professor's statements.
Answer: Your classmate would have learned from the chapter and/or lecture that muscle cell function is dependent on calcium and messages delivered by neurotransmitters. Calcium ions play the critical role of allowing myosin heads to bind to the actin filaments, pulling them toward the center of the sarcomeres and contracting the muscle. Neurotransmitters "ferry" the message to the muscle cell that it's time to release calcium and start the contraction process. Without them, muscles such as the diaphragm, which helps us breathe, would malfunction.
