Document Summary
What is the definition of physiology according to. Physiology is the study of how animals work. Development, environment, random processes, natural selection, reproduction: physiology is integrative, physiology obeys physical and chemical laws, physiological processes are shaped by evolution, physiological processes are regulated to maintain homeostasis (feedback loops) When a physiologist interested in a phenomenon at one level will study it at a lower level. Physiology makes the assumption that we can learn about a system by studying the function of its parts. Emergent properties are due to the interactions of the component parts of the system. A model animal has features that are conducive to experimentation and understanding. It has to be phylogenetically relevant (not too far on the phylogenetic tree) Has to have the right anatomical features (has to be the right size to be studied: ex: squid giant axon (can be easily seen and readily manipulated, ex: oocytes of xenopus easy to microinject foreign genes.
