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.
Selective publication in reporting results of antidepressant trials exaggerates the effectiveness of the drugs, according to a report in the January 17 issue of the New England Journal of Medicine.
There is a widespread misunderstanding that stance and gait are automatic processes, i.e. not controlled by the human brain. However, the fact that many patients with brain disorders are no longer able to walk and engage in simple conversation at the same time makes it abundantly clear that our consciousness and our thinking do indeed control such apparently simple actions.
Prescription drugs now used to treat human immunodeficiency virus infection in adults may prevent the vaginal transmission of HIV, researchers at UT Southwestern Medical Center have found.
By using a process called whole organ decellularization, scientists from the University of Minnesota Center for Cardiovascular Repair grew functioning heart tissue by taking dead rat and pig hearts and reseeding them with a mixture of live cells. The research will be published online in the January 13 issue of Nature Medicine.
The roundworm C. elegans, a staple of laboratory research, may be key in unlocking one of the central biological mysteries: why we sleep.
Do your ears ring after a loud concert? Nerves that sense touch in your face and neck may be behind the racket in your brain, University of Michigan researchers say.
Overweight people who lose a moderate amount of weight get an immediate benefit in the form of better heart health, according to a study conducted at Washington University School of Medicine in St. Louis.
Scientists at Washington University School of Medicine in St. Louis have used yeast cells to better understand a collection of proteins associated with the formation of actin networks, which are essential to cell movement.
UCLA researchers found that women with IBS cannot effectively turn-off a pain modulation mechanism in the brain, which causes them to be more sensitive to abdominal pain, compared to women without IBS.
People who experience brief periods of blocked blood flow may be better conditioned to survive a full-blown heart attack later, according to new research from the University of Cincinnati (UC).
In the 21st century, human tissue can be generated from stem cells and severed limbs are successfully reattached, while the physiological processes governing life's most fundamental event, childbirth labor, remain a medical mystery.
The number of overweight and obese Americans continues to grow rapidly. Today, 50 percent of adults are overweight and up to 20 percent are obese. While the number of overweight/obese children is at an all time high, the steady increase of overweight infants -- individuals under 11 months old -- is alarming.
A recent study by University of Virginia researchers demonstrates that the use of an acute, localized static magnetic field of moderate strength can result in significant reduction of swelling when applied immediately after an inflammatory injury.
A new study finds that a chemical found in the body is capable of promoting weight loss, improving insulin resistance and reversing diabetes in an animal model.
Researchers at Johns Hopkins and Ohio State University have found that the number of copies of a particular gene can affect the severity of colon cancer in a mouse model. Publishing in the Jan. 3 issue of Nature, the research team describes how trisomy 21, or Down syndrome in humans, can repress tumor growth.
Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago.
Researchers from Boston University School of Medicine (BUSM) have found that vitamin D2 is equally as effective as vitamin D3 in maintaining 25-hydroxyvitamin D status.
Researchers at Wake Forest University School of Medicine have shown that the effects of sleep deprivation on cognitive performance can be reversed when the naturally occurring brain peptide, orexin-A, is administered in monkeys.
Current regulatory policies should be strengthened to ensure acceptable cardiovascular safety of drugs developed primarily for non-cardiovascular medical problems, according to a recent presentation made by Dr. Jeffrey Borer, an authority in cardiovascular medicine and surgery at NewYork-Presbyterian Hospital/Weill Cornell Medical Center in New York City.
The research field has grown from grapheme-colour synaesthesia to include other forms of synaesthesia in which flavours are evoked by music or words (lexical-gustatory synaesthesia), space structures by time units, colours by music, etc.
