Skeletal muscle has a defined contraction period, causing the full contraction of every stimulated fiber. (8 pts)

Part 1 - What determines the length of time during which the fiber contracts?

Part 2 - What ends the contraction, so relaxation can begin? (not including the termination of the NMJ stimulation)

Part 3 - Taking the previous two parts, and now adding in that the NMJ has stopped inducing depolarizations at the motor end plate, describe the events as the contraction cycle (each single twitch) ends.

Part 4 - Taking the previous three parts, and now adding in that the NMJ continues to induce depolarizations at the motor end plate, explain the generation of increased muscle tension as summation occurs.

Briefly describe the different forms of transport across a cell membrane ie; how a molecule moves across the membrane, and give examples. What is the sodium-potassium pump and why is it important? What is the difference between primary and secondary active transport? What is a secondary messenger and give an example?

Compare a contraceptive's perfect use with its typical use. Discuss factors that may influence each.

3)Despite being well anchored in the pelvic cavity,the uterus can prolapse. how does this happen?
4) Name the body system that is most important in maintaining homeostasis in the body and Briefly explain why ?

Discussion Question

1.  Larraine makes many financial choices that others are critical of: not selling her jewelry, spending her food stamps on lobster, paying for cable TV instead of saving. From Larraine’s perspective, why do these choices make sense?  What do these choices mean to her? What does Matt mean when he says that Larraine spends money because she is poor and not the other way around (i.e. she's poor because of her spending)? Have you ever spent money you didn't really have on something you really didn't need? Why?

1. Interactions of dietary nutrients play an important role in inducing a specific nutrient deficiency.  Provide one (1) example each of a specific interaction between nutrients that occurs only in nonruminant animals and another interaction unique to ruminant animals.  Be sure to define which nutrient(s) are causing the deficiency and the nutrient that becomes deficient.  Explain why the interaction is unique to either nonruminants or ruminants.
   1. Nutrient interaction specifically seen in nonruminant animal:
   2. Nutrient interaction unique to ruminant animals:

EXPERIMENT 11 CASE STUDY: BLOOD

A 52-year old man weighing 60kg is taking 100mg Iron supplement every night due to his mild Anemia. He noticed that the color of his stool became dark brown to black and tarry, with a sudden change in consistency. He decided to stop taking Iron supplements however, his condition is still the same as well as the color of his stool. He then consulted the doctor after a week, as it is accompanied by persistent abdominal discomfort and constipation.
