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.
Your knees take the brunt of the increased demands on your lower body in terms of the amount of muscle mass used and joint flexion when you compare walking to running. By a lot. Why? Because you’re human.
University of Toronto researchers have identified individual cells in the adult mouse pancreas capable of generating insulin-producing beta cells.
Despite improvements in earlier diagnosis and treatment, cardiovascular disease is far and away the leading cause of death in the U.S. and the world.
Penn State College of Medicine researchers recently were awarded a five-year, $7 million grant from the National Heart, Lung and Blood Institute of the National Institutes of Health to conduct a series of studies on human circulation.
As her PhD defended at the Public University of Navarre, telecommunications engineer Ixone Arroabarren has analysed the vibrato, one of the most important tools of classical singers.
Researchers at the NIH's National Institute of Mental Health (NIMH) have identified a relationship between a small section of one gene, the brain chemical messenger glutamate, and a collection of traits known to be associated with schizophrenia.

Oregon Health & Science University researchers will more quickly move benchtop discoveries toward drug discoveries with the help of a new, service-oriented laboratory focused on bioanalysis and pharmacokinetics.
Cyntellect a privately-held biotechnology company, has announced the issuance of U.S. Patent No. 6,753,161 covering the Company's LaserFect(TM) technology.
Scientists have produced a prion protein that can trigger the development of a neurological disorder in mice that is similar to "mad cow" disease, according to a new study supported by the National Institute on Aging, a part of the National Institutes of Health.
The DNA of rare and endangered species is to be preserved for future generations, thanks to a groundbreaking new project involving scientists at The University of Nottingham, the Institute of Zoology and London’s Natural History Museum.
Feeling sick can be "all in the head" for people with inflammatory disorders or for those receiving immunotherapy, say Robert Dantzer and Keith Kelley, professors in the department of animal sciences at the University of Illinois at Urbana-Champaign.
For most of us, hot weather leads to elevated internal and skin temperatures, which increase sweat rates and skin blood flow. How much we sweat can also depend on nonthermal factors such as exercise, baroreceptor loading status, and body fluid status.
Every morning, millions of adults consume voluminous cups of coffee, seeking the jolting effect of caffeine. As these adults consume their coffee, they do so unaware that some of the youngest Americans are also getting a treatment of caffeine - not to stay awake, but to assist in treating a major sleep disorder found in some neonates.
Russian scientists are currently creating a pleasant and harmless vaccine, and edible one at that. So far, they managed to incorporate the protein gene – HIV antigen in tomatoes. The research is supported by International Science and Technology Center.
A protein responsible for regulating acid levels within cells - and pumping out acid accumulated in cardiac cells after a heart attack - activates in direct response to changes in a cell's volume, according to a new study by researchers at UT Southwestern Medical Center at Dallas.
Researchers from the University of Iowa have have shown for the first time that gene therapy delivered to the brains of living mice can prevent the physical symptoms and neurological damage caused by an inherited neurodegenerative disease that is similar to Huntington's disease (HD).
Scientists at the University of North Carolina at Chapel Hill have discovered key steps involved in regulating nerve growth and regeneration that may have implications for spinal cord research.
The Children's Digestive Health and Nutrition Foundation (CDHNF) with the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) today announced the launch of a new educational campaign on celiac disease
New findings about a protein that keeps cells alive by opening and closing pores within a cell's membrane may open the door to the development of new antibiotics.
