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.
New research published in the international journal Neurobiology of Aging by Marc Poulin, PhD, DPhil, finds that being physically fit helps the brain function at the top of its game.
Researchers at Oregon Health & Science University's School of Dentistry have discovered a novel function of the peptide known as Nerve Growth Factor (NGF) in the development of the trigeminal nerve.
Researchers at Oregon Health & Science University's School of Dentistry have discovered that the nerve cells controlling heart rate and blood pressure synthesize a molecule known to be critically important for proper nervous system growth.
Ten years ago, the Chinese National Human Genome Center at Shanghai (South Center, hereafter) was established in the Zhangjiang HiTech Park of Pudong District in Shanghai.
Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society.
When there is a threat of disease during pregnancy, mothers produce less aggressive sons with more efficient immune systems, researchers at The University of Nottingham have discovered.
The study, which appears in the December 18 online version of Cell Stem Cell and the January 2009 print edition of the journal, provides proof of principle that alternative sources of stem cells can be created.
Although irritable bowel syndrome (IBS) is the most common disease diagnosed by gastroenterologists, it's also one of the most misunderstood.
The naturally high levels of leptin in diabetic patients may reduce the effectiveness of drug-eluting stents used to treat heart blockages, but using a chemical that differs from the one commonly used to coat stents could counteract this effect.
Vanderbilt University Medical Center investigators have now discovered a functional link between reward and stress. They found that dopamine - the brain's chief reward signal - works through corticotrophin-releasing factor (CRF) - the brain's main stress signal - to increase the activity of a brain region involved in addiction relapse.
Van Andel Institute (VAI) researchers are the first to apply a new technology to measure on a large scale the presence of genes in blood spots - the blood drawn from newborn infants to screen for health-threatening conditions.
While radiation treatments deliver precise doses of high-energy X-rays to stop cancer cells from spreading or to shrink tumors, oncologists have become increasingly concerned about inadvertent exposures during head and neck cancer treatments to nerves responsible for upper body mobility.
Anyone will tell you that stress is bad for the heart. Many people also know about the toxic effects of anxiety and depression.
You probably know that poor diet and lack of exercise can lead to dangerous deposits of fatty plaques in arteries.
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have identified a potential new avenue for altering lung development in the embryo which may help to improve the outcome for very premature babies.
People who use weight training to ease their lower back pain are better off than those who choose other forms of exercise such as jogging, according to a University of Alberta study.
A University of Iowa study provides insight into a calcium-sensing enzyme already known to play a role in irregular heartbeats and other critical functions.
A vigorous 60-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while 90 minutes of weight lifting affects the level of only ghrelin, according to a new study.
Children who are overweight or obese are over two and a half times more likely to suffer injuries to their upper and lower extremities following a motor vehicle crash compared with normal weight children, according to a new report from the Johns Hopkins Bloomberg School of Public Health's Center for Injury Research and Policy.
Reducing the activity of a gene called FKBP12 in the brains of mice affected neuron-to-neuron communication (synapse) and increased both fearful memory and obsessive behavior, indicating the gene could provide a target for drugs to treat diseases such as autism spectrum disorder, obsessive-compulsive disease and others, said researchers from Baylor College of Medicine in Houston in a report in the current issue of the journal Neuron.
