Physiology
Adenosine triphosphate (ATP) is the power source of many biochemical reactions. It is produced in the cell structures and system listed at the left to energize the important life processes listed on the right. An abbreviated chemical formula of the structure of ATP is also shown. The two high-energy P―O―P bonds are responsible for its power.
In the 19th century, physiology emerged as a distinct scientific discipline, transitioning from a branch of anatomy to a rigorous field utilizing chemical, physical, and experimental methods. Several key figures are recognized as the founders of modern physiology:12
- Claude Bernard: A French physiologist who pioneered experimental medicine. He is noted for his work on the pancreas, glycogen, and vasomotor nerves. His most seminal contribution was the concept of the internal environment (milieu intérieur), which laid the foundation for the understanding of homeostasis.132
- Johannes Müller: A German professor whose textbook, Handbuch der Physiologie des Menschen, and personal influence were instrumental in establishing physiology as a science in Germany.12
- Carl Ludwig: A founder of the physicochemical school of physiology in Germany. He introduced innovative methods and instruments, such as the kymograph, and established a model research institute in Leipzig.42
- Justus von Liebig: A German chemist who expanded the chemical approach to physiological problems, significantly influencing medical physiology.2
- Sir Michael Foster: A British physiologist who established the first laboratory course in medicine and was instrumental in founding the Physiological Society and the Journal of Physiology.2
