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.
Physicians monitoring patients who have undergone gastric bypass surgery should be on the alert for a new, potentially dangerous hypoglycemia (low blood glucose) complication that, while rare, may require quick treatment, according to a new study
Technology that more closely mirrors the natural fertilization process is showing promise as a new method of in-vitro fertilization, researchers at the University of Michigan Health System have found.
Researchers at UT Southwestern Medical Center have discovered that the small intestine communicates with the liver to control the production of bile acids - a finding that has great medical implications in treating people at risk for certain types of liver disease.
The centre, based at the UCL (University College London) Department of Human Communication Science, will see ESRC inject £4.5 million over an initial 5 year period into a study of deafness, linguistic systems and communication that will run over a 10 year programme.
A research team led by scientists at The University of Texas Medical School at Houston has determined the structure of an enzyme that when defective causes an inherited disease that afflicts sufferers with severe abdominal pain, psychiatric symptoms, skin fragility, and light sensitivity.
The babies of women with diabetes are two to five times more likely to develop birth defects than offspring of women without the disease.
Multi-vitamin products, nutritional supplements and parents tout the need for such mineral elements as calcium, zinc, phosphorus, iron and others.
It's often said that the key to Bill Bradley's basketball success was summed up in the title of the 1965 book by John McPhee, "A sense of where you are." Bradley always seemed to know where all nine other players were, where Bradley himself was in relation to the basket – and where the open spot was to be found for his stylized jump shot.
Night-time hemodialysis patients may have a greater capacity to repair their hearts and blood vessels compared to those on conventional dialysis three times a week, according to a study in the October issue of the American Journal of Physiology - Renal Physiology, published by the American Physiological Society.
Since the discovery of the structure of DNA by James Watson and Francis Crick in 1953, the paradigm for DNA replication has stated that the DNA itself codes for the appropriate pairings for replication.
Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction.
Even though there are definitive guidelines to diagnose IBS through simple blood tests, many IBS patients have additional procedures and surgeries that rarely result in relief or any additional diagnostic findings.
A pulsing heart cell is giving Oregon Health & Science University researchers insight into how it sends and receives signals, and that's providing clues into how heart disease and other disorders develop.
Immune system cells are connected to each other by an extensive network of tiny tunnels that, like a building's hidden pneumatic tube system, are used to shoot signals to distant cells.
Neuroscientists at Washington University School of Medicine in St. Louis have assembled a first-of-its kind atlas of the folds of the cerebral cortex, the wrinkled surface layer of the brain credited with many of the higher cognitive functions that make us human.
A University of California - San Francisco (UCSF) study has revealed new information about how the brain directs the body to make movements. The key factor is "noise" in the brain's signaling, and it helps explain why all movement is not carried out with the same level of precision.
Some people call it "the dark time," the period between when a person is diagnosed with Parkinson's disease and when treatment with medication begins.
Chris Wyatt is a Virginia Tech electrical engineer who is attempting to provide the medical community with better, quicker, and more relevant images of the human body. The side effects are not bad either - lower medical costs, new treatments, and earlier disease detection.
Neuroscientists at the University at Buffalo have shown in two recently published papers that destabilization of structures called microtubules, intracellular highways that transport receptors to their working sites in the brain, likely underlie many mental disorders and could be promising targets for intervention.
Researchers at the University of Illinois at Urbana-Champaign say it may be because estrogen virtually eliminates levels of a vitally important regulatory protein.
