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.

UVA biologists discover new information about how Ebola virus works

GUMC neuroscientists: Speech perception must have evolved from animals

Neuroscientists at Georgetown University Medical Center (GUMC) have defined, for the first time, three different processing stages that a human brain needs to identify sounds such as speech - and discovered that they are the same as ones identified in non-human primates.

Scientists discover linchpin protein that drives mitochondria's calcium machinery

Mitochondria, those battery-pack organelles that fuel the energy of almost every living cell, have an insatiable appetite for calcium. Whether in a dish or a living organism, the mitochondria of most organisms eagerly absorb this chemical compound.

Endocrine Society honors BUSM professor with The Delbert A. Fisher Research Scholar Award

Michael F. Holick, PhD, MD, director of the General Clinical Research Center and professor of medicine, physiology and biophysics at Boston University School of Medicine, is this year's recipient of The Delbert A. Fisher Research Scholar Award from the Endocrine Society for his scholarly work on the history of endocrinology.

Biomedical engineers analyze and duplicate the neural mechanism of learning in rats

Scientists have developed a way to turn memories on and off-literally with the flip of a switch. Using an electronic system that duplicates the neural signals associated with memory, they managed to replicate the brain function in rats associated with long-term learned behavior, even when the rats had been drugged to forget.
