has a smaller diameter and less myelination. Predict Question 2: How will the conduction velocity in the C fiber compare with that in the B Fiber? Your answer : d. The conduction velocity will be the same in both fibers. Stop & Think Questions: 3. Note the difference in time between the action potential recorded at R1 and the action potential recorded at R2. The distance between these sets of recording electrodes is 10 centimeters (0.1 m). Convert the time from milliseconds to seconds‚ enter

through the 20 MWCO membrane? How well did the results compare with your prediction? Since the chemical formula for urea is (NH2)2CO and its molecular weight is about 60. It will not diffuse through the 20 MWCO membrane because it does not ionize. 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? Glucose will diffuse through the 200 MWCO membrane because its MW is 180. The MW of the protein

PhysioEX notes Autorhythmicity- heart’s ability to trigger its own contractions Phase O- a lot like depolarization in neuronal action potentials. Sodium channels open‚ increase of sodium INTO cell. Phase 1- sodium channels close‚ potassium channels close‚ decrease in potassium and sodium. Calcium channels open‚ increase of calcium into cell. Phase 2- Plateau phase‚ membrane still depolarized (contract). Potassium channels closed‚ L-type calcium channels stay open. Lasts 0.2 seconds/200

3-Day Exercise Activity Analysis Starting an exercise plan is easy the problem will be sticking to it. My current exercise habits are walking for about 30 minutes at least three times a week and playing Michael Jackson’s The Experience on the Wii. These exercises allow incorporate aerobics and stretching into my exercise. I stretch before I begin to workout‚ the Wii and walking routine gets my heart rate going. During my workouts I use a waist trimmer. I zip it up around my abdominal area and

3 Day Exercise Activity Analysis Yakini Wisdom Axia College SCI/241 August‚ 15‚ 2013 Ose Martinez The habits that I have developed through the months in reference to exercising are phenomenal I run 4 days out the week and lift the other days. The times that I do miss my run is‚ because of the kids or it’s raining. I substitute the non-run days with cardio. The way my body has adapted to the change is unreal. I am also‚ training to be a personal trainer‚ so the impact of that conditioning is awesome

Glomerular Filtration Activity 1: Effect of Arteriole Diameter on Glomerular Filtration 1. Compare this data with your baseline data. How did increasing the afferent arteriole radius affect glomerular filtration rate? >>Increasing the afferent arteriole radius pushed the glomerular pressure‚ the glomerular filtration rate‚ and the volume of urine to be higher than the baseline data. Increasing the afferent arteriole radius increased the glomerular filtration rate. 2. Under
