Saltatory conduction propagates action potential more rapidly than contiguous conduction. Introduction: An action potential is a short, quick, large (100 mV) membrane potential change, during which the potential is reversed to make the inner cell more positive than the exterior. The axon hillock is the trigger area for the neuron because it is the site where the action potential is activated or initiated by a sufficiently large graded potential. When the axon hillock initiates an action potential, the rest of the nerve fiber is not activated by any more triggering effect. The impulse is carried out automatically throughout the neuron by one of two modes of transmission: adjacent conduction and saltatory conduction, without further stimulus.

Discussion entries must be at least 250 words to fulfill the assignment requirements. You must complete your entry before you will be able to see the responses of other students. Responses to other students are encouraged but not required. Grading for discussion entries will be based on application of course concepts, proper grammar, and correct punctuation. Read one the attached article and explore the Human Development Index (https://hdr.undp.org/data-center/human-development-index#/indicies/HDI). In your opinion, is the Human Development Index a good measure of the well- being of the people of a nation? Are the items measured in the HDI valid and relevant in the modern global economy? How are they related to the political economy of a nation? The attached articles propose some alternative measures of well-being. In your opinion, are there other measures of well-being that might be better alternatives to the items in the current HDI?
