1. A female volleyball player enters the athletic training room following practice and complains of pain on the outside of her right ankle. She tells the athletic trainer that it has been progressively getting worse over the last 3 weeks. Identify the classification of this injury (e.g., acute, chronic, macro trauma, micro trauma).
2. You begin your observation and determine that she has mild edema over the peroneal tendons by the lateral malleolus. She states she has pain with passive stretching and pain with active and resisted motion. Explain the injury you suspect.
3. Using the information in question 2, describe how you would treat this injury.

We stay healthy because our bodies keep everything in balance. Which system, that we studied this semester, do you think is the most important in maintaining homeostasis? In your discussion be sure to include the main function of the system, cells and tissues that are involved, and how it maintains homeostasis. You can also include how it helps regulate other systems if you think that is important

1. Dr.W is trying to explain the concepts of resting membrane potential, equilibrium potential, and membrane potential to the students in her laboratory. To do this, she uses a dish of cultured motor neurons so that she can alter the solution covering the cells and she can use a recording electrode to pierce one of the cells and determine its membrane potential relative to the extracellular fluid. She asks you a number of questions before and after she alters the conditions around the cell.
