Action Potential Depolarization And Repolarization

Where a stimulus is applied to the neuron, the polarity of the ions is disrupted at the same location. Thus, that location is said to be depolarized. The ions in adjacent areas along the neuron then attempt to restore the original polarity at the location of the stimulus. However, as repolarization occurs in the area of the stimulus, the adjacent areas themselves become depolarized. This results in a wavelike progression of depolarization/repolarization along the length of the neuron. By this means, information is transferred along the neuron.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
