What if we add specific membrane characteristics into the mix? Let's say that you also find a fossil record of a different, related antelope species that apparently had motor neurons with different characteristics. In fact, because you are a magical neuroscientist, you are able to determine the neuron had a resting membrane potential of ?65 mV and a threshold potential of ?40 mV and, when the neuron was stimulated and fired, the action potential brought the membrane potential to 20 mV when the animals were alive. In addition, you determined that the specific membrane resistance was 785 M?cm2 and the internal resistance was 1 x 106 M?/cm in these axons, and you measure the diameter of the axon to be 2 ?m and distance between each node of Ranvier to be 16 mm. A. Given all of this, please tell me whether the action potential will be able to propagate all the way down the axon? Please show all work and explain your answer. B. If the action potential is not able to propagate, then please tell me what is the maximum distance down the axon that the action potential is able to propagate. Again, please show all work and explain your answer.
How does this neurotoxin affect the nervous system's ability to stimulate skeletal muscle contraction? How does it affect the capability of skeletal muscle fibers to respond to stimulation.

In winter, plants exchange the saturated lipids in their membranes for unsaturated lipids. Unsaturated lipids are "bent" and keep the membranes more fluid since they cannot be stacked closely together. Of what benefit would this be for herbaceous pla..
