PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability

ACTIVITY 5 Exploring Various Breathing Patterns You will establish the baseline respiratory values in the first part of this experiment. 1. If the grid in the data control unit is not empty‚ click Clear Table to discard all previous data. 2. Adjust the radius of the airways to 5.00 mm by clicking the appropriate button next to the Radius window. Now‚ read through steps 3–5 before attempting to execute them. 3. Click Start‚ and notice that it changes to Stop to allow you to stop the respiration. Watch

REVIEW SHEET EXERCISE 12 Serological Testing NAME: LAB TIME/DATE: Positive and Negative Controls 1. Why are there a number of washing steps in serological tests? They are needed in order to remove any non specific binding that may happen. 2. Describe how you would know that you had a “false positive” result. What does this mean for the rest of your results? If it has a negative control then it’s a false positive so the results are invalidated. 3. Describe how you would

Danielle Rollins Cardiovascular Physiology Activity 1 1) Explain why the larger waves seen on the oscilloscope represent ventricular contraction. The ventricular contraction is when the blood is sent through the whole body as opposed to the atrial contraction that sends the blood to the heart and lungs. 2) Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. (Hint: relate your response to the refractory period of the cardiac action
