Abstract:
Physiology teaching began with Claudius Galenus (c. 126-199 AD), known as Galen, who is considered the initiator of experimental physiology. This discipline was consolidated in the XIX century with the discoveries of Claude Bernard, which influenced the way of teaching this discipline in universities, independently from Anatomy. In Mexico, physiology teaching started in 1580. It was at the beginning of the XIX century when Valentín Gómez Farías created the professorship in Medical Sciences and Daniel Vergara Lope carried out its consolidation when he implemented a lab course. Doctor José Joaquín Izquierdo established that this subject ought to be taught by teachers with experience in research. Undoubtedly, formative physiology teaching carried out in labs must strengthen the application of method and scientific methodology in students. In this symposium, we put forward that the change in physiology teaching must promote multidisciplinary research in students, who will formulate a research question and develop an experimental model that will let them integrate their basic knowledge of physiology, pharmacology, biochemistry, and functional anatomy under the supervision of a research teacher.

When the switch connecting the RL circuit is closed, a brief muscle contraction is observed. This is because, at a steady state, the inductor acts like a short...
The Scientific Method
Steps in the Modeling Process
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...

Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.
Liver Physiology
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
