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.
Ludwig-Maximilians-Universitaet in Munich neurobiologists present a new theory for the origin of the grid cells required for spatial orientation in the mammalian brain, which assigns a vital role to the timing of trains of signals they receive from neurons called place cells.
Scientists may be able to minimize the failure rate of drugs for diseases linked to high-calorie diets, such as colon cancer and type 2 diabetes, if they test treatments using a pig model, according to an international team of researchers.
Would you say that you are physically more active, less active, or about equally active as other people your age? Your answer might be linked to your risk of premature death decades from now - no matter how physically active you actually are, according to research by Stanford scholars Octavia Zahrt and Alia Crum.
It's like the Superman of viruses, astonishingly tough and able to survive in an environment that would dissolve flesh and bone. And now scientists have unlocked the secrets of its indestructibility, potentially allowing them to harness its remarkable properties to create super-durable materials and better treat disease.
Researchers at University of Massachusetts Medical School and Auburn University College of Veterinary Medicine are nearing human clinical trials on a genetic therapy for two rare neurological diseases that are fatal to children.
A new report by the National Academies of Sciences, Engineering, and Medicine proposes a strategy that the U.S. Environmental Protection Agency should use to evaluate the evidence of adverse human health effects from low doses of exposure to chemicals that can disrupt the endocrine system.
Healthcare practitioners regularly prescribe diet and exercise as a method for patients to lose weight. But exercise might not be equally effective in males and females, according to new research conducted at the University of Colorado, Anschutz Medical Campus.
Researchers have found that mice fed a palatable high-fat diet experience stress responses that resemble drug withdrawal when their food is switched to a low-fat diet.
Popular muscle building supplements, known as branched-chain amino acids (BCAA) are ineffective when taken in isolation, according to new research from the University of Stirling.
Stroke survivors may experience delayed recovery of limb function up to decades after injury, according to a new case study. The article, published ahead of print in the Journal of Neurophysiology, was chosen as an APSselect article for July.
A new study finds that moderate exercise does not impair kidney function in some people with chronic kidney disease (CKD).
A study by researchers at the University of Chicago Medicine shows that when mice that are genetically susceptible to developing inflammatory bowel disease (IBD) were given antibiotics during late pregnancy and the early nursing period, their offspring were more likely to develop an inflammatory condition of the colon that resembles human IBD.
Sure, you know how old you are, but what about your cells? Are they the same age? Are they older, younger? Why does it matter?
Men and women react differently to compounds associated with immune system response to bipolar disorder, according to Penn State College of Medicine researchers.
Doctors can't predict who will develop Type 1 diabetes, a chronic autoimmune disease in which one's own immune system destroys the cells needed to control blood-sugar levels, requiring daily insulin injections and continual monitoring.
Cell cannibalism in tumor samples has been observed for over a century, yet this unusual behavior is not well studied.
Do overweight children have more breathing limitations, intolerance for exercise, and breathlessness when exercising than normal weight children, leading to possible misdiagnosis for conditions such as asthma?
Many scientists are paying new attention to prebiotics, that is, molecules we eat but cannot digest, because some may promote the growth and health of beneficial microorganisms in our intestines, says nutritional microbiologist David Sela at the University of Massachusetts Amherst.
A recent study from the University of Nebraska-Lincoln has given new meaning to the concept of brain power by suggesting that physical strength might stem as much from exercising the nervous system as the muscles it controls.
Researchers from the Department of Nutrition, Exercise and Sports at the University of Copenhagen today announced the findings from a weight loss biomarker study published in the American Journal of Clinical Nutrition.
