A Brief History of Animal Physiology
Hippocrates (father of medicine): treatment of diseases
Aristotle determined the structure and function
Claudius Galenus had experiments to find out about bodily functions
o He had experiments that involved dissecting organisms
o Ex. He experimented with the vocal cords of a pig
Ibn al-Nafis was the 1st to describe the anatomy of the heart, lungs and pulmonary circulation
Francois Fernal outlined knowledge about human disease
Andreas Vesalius created the 1st anatomy textbook
William Harvey identified the path of blood through the body
Before the 18th century physiologists can be divided into two groups
Iatrochemists: believed the body function only involving chemical reactions
Iatrophysicists: believed that there were only physical processes involved
Hermann boerhaave and Albercht von Haller proposed that both chemical and physical
processes are at work
In the 19th century Mattias schleiden and Theodor Schwann proposed that created the cell
theory
Bernard came up with the theory that there is milieu interior (internal environment for cells
Per Scholander: responses of vertebrates and warm blooded organisms
C. Ladd Prosser: central pattern generators: groups of neurons that regulate rhythmic
behaviour
Knut Scmidt-Nielsen devoted his career to understanding how organisms live in harsh
environments
George Bartholomew combined animal physiology with ecology
Peter Hochchka and George Somero founded combing biochemistry and physiology
Subdisciplines in Physiological Research
Modern physiology is multidisciplinary
Physiological subdisciplines can be distinguished by the biological level of organization
Cell and molecular physiologists: study the phenomena that occurs at the cellular level; study
molecular genetics, signal transduction and metabolic biochemistry
System physiologist: concerned about how interact and carry out specific responsibilities; study
sensory systems
Organismal physiologist: concerned with the way an intact animal undertakes a specific process
or behaviour; study metabolic rate; focus on a particular group of organisms
Ecological physiologist: studies how physiological properties about how the distribution and
abundance of species
Integrative physiologist understand physiological processes at a variety levels
