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.
Researchers from the Uniformed Services University of the Health Sciences (USU) are pursuing efforts to find new ways to prevent and to treat the increasing numbers of combat troops who are suffering from injuries due to traumatic brain injury (TBI).
A research team led by Carole Thivierge, from Universit Laval's Institute of Nutraceutics and Functional Foods, shows that omega-3 fatty acids from fish oil have a positive effect on the metabolism of muscle proteins.
A new study in The American Journal of Gastroenterology suggests that smoking may determine which part of the intestinal tract is attacked in those who suffer from Crohn's disease.
There is renewed hope for treatment of a rare genetic condition that causes rapidly accelerated aging and leads to an average life expectancy of 13 years.
While men and women both get high blood pressure and related kidney disease, the path to get there is shorter, steeper and just different for men, researchers say.
Statin drugs, known primarily for their ability to lower cholesterol, also may reduce the overactive sympathetic nervous system response that contributes to the worsening of heart failure and increases the risk of sudden cardiac death, two University of Missouri-Columbia researchers have found. Heart failure is the leading cause of morbidity and mortality in the United States.
A new study examining the overall and gender-related effects of laparoscopic gastric banding surgery (LGBS) on insulin resistance, body composition, and metabolic risk markers six months post-surgery has found significant improvements in insulin resistance.
A new study finds that exposure to a chemical component of diesel exhaust particles can compromise the ability of resistance arteries to regulate blood flow to bone marrow.
The eye, often called the window to the soul, may become a window to the mysteries of muscular dystrophy, a debilitating muscle disease that often leads to death in early adulthood.
What creates that irresistible urge for a bag of potato chips or a hunk of chocolate cake, as opposed to a nice crisp apple? Can food urges be irresistible?
Medicinal plants are an integral part of African culture, one of the oldest and most diverse in the world.
Drama certainly has the power to entertain, but can it also change behavior? A play about substance abuse was successful at prompting audience members to participate in substance abuse prevention activities, according to Allyn Howlett, Ph.D., from Wake Forest University School of Medicine.
For the first time, scientists have used a laboratory mouse model to mimic the development of human alcohol-induced breast cancer.
For almost one hundred years the brain's ,central command, system , whose charge includes controlling the body's cardiorespiratory response to exercise , has been pursued. Animal experiments and functional imaging studies have provided clues to the location of this system, but the underlying electrophysiological activity has never been measured.
A team of researchers investigating the effects of oxytocin, a peptide produced by the brain that regulates social behavior, has found that it can prevent detrimental cardiac responses in adult female animals exposed to social isolation.
Because of new imaging technology, researchers are getting a better understanding of a physiological paradox: how insects, which have a respiratory system built to provide quick access to a lot of oxygen, can survive for days without it.
A Medical College of Wisconsin and Children's Research Institute team in Milwaukee has created a free, searchable genetic database that will significantly improve diagnostic testing and genetic tracking of human and animal influenza viruses.
Morphine, as little as a single dose, blocks the brain's ability to strengthen connections at inhibitory synapses, according to new Brown University research published in Nature.
Three of America's best known voices in the debate about evolution in the teaching of science will meet to discuss the issue on Sunday, April 29, 2007 in Washington, DC.
In a unique collaborative paper in PLoS Medicine , Georgetown University Medical Center's Adriane Fugh-Berman and a former Eli Lilly drug rep reveal the tactics used by drug reps to manipulate physicians into selling drugs.
