Teaching Physiology and the World Wide Web: Electrochemistry and Electrophysiology on the Internet.

Presents two examples of laboratory exercises using the World Wide Web for first-year medical students. The first example introduces the physical laws that apply to osmotic, chemical, and electrical gradients and a simulation of the ability of the sodium-potassium pump to establish chemical gradients and maintain cell volume. The second module simulates action according to the Hodgkin-Huxley model. (Author/AIM)
