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.
As the brain develops, each neuron must find its way to precisely the right spot to weave the intricate network of links the brain needs to function. Like the wiring in a computer, a few misplaced connections can throw off functioning for an entire segment of the brain.
Even the very lowest levels of radiation are harmful to life, scientists have concluded in the Cambridge Philosophical Society's journal Biological Reviews.
People with diabetes often develop clogged arteries that cause heart disease, and new research at Washington University School of Medicine in St. Louis suggests that low vitamin D levels are to blame.
Smoke-divers are exposed to high temperatures, physical exhaustion and stress, and they can easily exceed the limits of what good health can tolerate. A new method based on measurements made by a wireless sensor system lets them know when the body has had enough.
Low antioxidant levels contribute to increased blood pressure during exercise for people with peripheral arterial disease, according to researchers at Penn State Hershey Heart and Vascular Institute.
World-renowned scientists are taking what they've learned from their multicenter research collaboration studying the health impact of fatty acids on diverse populations to set up a genetics center in India.
Scientists for the first time have evidence showing how a widely used type of "targeted" cancer drug can be dangerous to the heart.
Excessive turnover of cells in the placenta may trigger an unnatural increase in blood pressure that puts mother and baby at risk, researchers say.
Weight loss, whether it's from dietary changes alone or from diet combined with exercise, can help improve the quality of sleep among people who are overweight or obese, according to a new study by Johns Hopkins researchers.
Katherine L. Knight, PhD, one of the nation's leading immune system researchers, has been named 2012 Senior Scientist of the Year at Loyola University Chicago Stritch School of Medicine. Sakthivel Sadayappan, PhD, FAHA, who is doing groundbreaking research on a protein that is critical for the normal functioning of the heart, has been named 2012 Junior Scientist of the Year.
A new study reveals that black Americans display lower levels of vitamin D and greater pain sensitivity compared to white Americans. Findings published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), indicate that vitamin D deficiency may be one of many factors that account for increased pain in older black Americans with knee osteoarthritis (OA).
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, today reported its consolidated financial results for the third quarter 2012, and company highlights.
Autosomal-dominant polycystic kidney disease (ADPKD) is one of the most common genetic disorders, affecting one in every 1,000 people and responsible for up to ten percent of patients on dialysis worldwide. The disease is characterized by the development of cysts that lead to progressive kidney failure and necessitate dialysis or a kidney transplant in most patients aged around fifty. Moreover, the persistent cyst growth causes high blood pressure and painful complications.
During the early developmental stages of vertebrates-animals that have a backbone and spinal column, including humans-cells undergo extensive rearrangements, and some cells migrate over large distances to populate particular areas and assume novel roles as differentiated cell types.
Weill Cornell Medical College announced today that it is a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation.
The coming crisis for society caused by millions of people who are seriously overweight will be discussed at a University of Greenwich public lecture on 28 November.
A stroke is a sudden interruption of blood flow to the brain which deprives the brain of oxygen and nutrients. Approximately two millions brain cells die each minute during a stroke. This can lead to brain damage, physical and mental disability and death.
A new study conducted by researchers at the University of Cordoba links moderate physical activity in males with better hormone levels and sperm characteristics that favour reproduction compared to sedentary men.
Scientists at The Scripps Research Institute (TSRI) have discovered the first selective inhibitors of an important set of enzymes. The new inhibitors, and chemical probes based on them, now can be used to study the functions of enzymes known as diacylglycerol lipases (DAGL), their products, and the pathways they regulate.
As men and women age, increasing quantities of fat tissue inevitably take up residence in skeletal muscle. A small study of older and younger men conducted at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University suggests that a build-up of a fat molecule known as ceramide might play a leading role in muscle deterioration in older adults.
