Physiology News and Research

RSS

Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.

Summary of the latest research into how blood pressure is controlled

The problem of high blood pressure has reached pandemic proportions, causing premature death through heart attacks, strokes and kidney disease in a third of the UK population. For decades, scientists have battled at length over its cause yet still cannot agree; is the kidney or the brain to blame?

Forgotten and lost -- when proteins 'shut down' our brain

Which modules of the tau protein, in neurons of Alzheimer disease patients, may act in a destructive manner were investigated by researchers from the Max Planck Institute for Biophysical Chemistry (Göttingen) and the Max Planck Unit for Structural Molecular Biology (Hamburg) with the help of Nuclear Magnetic Resonance Spectroscopy ( PLoS Biology , February 17, 2009).
