Choose two of the following essays. (5 pts. each – total 10 pts). Choose an extra as your bonus and mark with a * or write bonus, or do the extra case study (only ONE extra essay for the bonus). 1.) Despite bone strength, fractures are fairly common occurrences. Briefly describe each step in the healing/repair of a fractured bone. (4 pts). List and describe any 2 types of fractures. (1 pt). 2.) List and briefly describe the function of the four components of synovial joints (2 pts). List one specific type and example of each classification of synovial joints (nonaxial, uniaxial, biaxial, multiaxial) (3 points). 3.) You completed a virtual muscle physiology lab. Think about that lab and lecture material to answer the following. The muscle in the experiment did not contract until the voltage of 0.5 mv. Why did this occur? (1) How are treppe and wave summation different (what specifically causes each?) (1) How is tetany different from wave summation? (describe specific causes of each) (1.5) What are three causes of muscle fatigue?(1.5) 4.) Describe the function of the following chemicals for muscle contraction (all events from the neuromuscular junction to relaxation): Na+ (.5), K+ (.5), Ca++ (1.5), ATP (1.5), ACh (.5), and AChase (.5). 5.) Compare and contrast the three types of muscle fibers. Include 1 similarity all three share (1) and 4 specific differences (cellular such as type of metabolism, myoglobin, mitochondria, size, activities best suited for, etc. ) between them (4).
