ELETROPHYSIOLOGY FUNDAMENTALS: MEMBRANE POTENTIALS

Abstract

Electrophysiology is of fundamental importance for the professionals in the medical field. However, there are difficulties in its understanding by students.Based in our teaching experience, we feel the need to help the student who is getting started in this subject or that wants to review it. Thus, we have prepared an easy, useable auto-instructional tool of teaching-learning, where the sequential mastery of the contents favors new cognitive acquisitions. The current tool aims at handling the chemical-physical principle of bioelectrogenesis supplying the basis to study neurophysiology, endocrinology and cardiac electrophysiology inter alia. Preceded by a theoretical introduction and objectives it presents a logical, articulated and hierarchical sequence of seventy objective, multi-choice questions, being fifty nine in the basic domain and eleven in the applied domain. They aim to stimulate the student to discover, by means of a logical-deductive reasoning, bioelectrical fundamentals of the generation and maintainance of the membranane potential. Parallel with the proposition contents, several reinforcing insets are placed about the essential concepts, or that are considered relevant or special applications of the subject. At the end an answer list is presented. The tool was used in student group activities with the biology area students with satisfactory results.
