so the dose was still too small. Part 3: 8. The normal rat’s BMR increased from the TSH injections. 9. The thyroidectomized rat’s BMR increased by a little but the BMR of the normal rat was still bigger and so the dose was too small. 10. The hypophysectomized rat’s BMR increased from the TSH‚ but yet again‚ the normal rat’s BMR was still more‚ so the TSH dose was again too small. Part 4: 11. The normal rat’s BMR decreased from the PTU injections and it developed the palpable

Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

ACTIVITY 1: THE RESTING MEMBRANE POTENTIAL 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? When the diffusion is greater on one side‚ the other side will slow down. 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? There are two potassium’s for every sodium so the increase of potassium will make it more
