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.
Less than 1 percent of the population has been diagnosed with Long QT syndrome – a rare heart condition that can cause chaotic, sometimes fatal, heart rhythms.
Researchers at Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center have identified a previously unrecognized form of hormone therapy-resistant prostate cancer, as well as a set of molecules that drive its growth.
A new study from The University of Toledo College of Medicine and Life Sciences has shown gut bacteria can reduce the effectiveness of certain blood pressure drugs.
When something goes wrong in mitochondria, the tiny organelles that power cells, it can cause a bewildering variety of symptoms such as poor growth, fatigue and weakness, seizures, developmental and cognitive disabilities, and vision problems.
DNA mutations are essential to the rapid development of an array of antibody-producing immune cells called B cells that collectively can recognize a vast number of specific targets.
Researchers at the Francis Crick Institute have developed an imaging technique to capture information about the structure and function of brain tissue at subcellular level – a few billionth of a metre, while also capturing information about the surrounding environment.
Cystic fibrosis is a rare genetic disease which can cause very serious symptoms. In particular, patients suffer from chronic bacterial infections that can lead to respiratory failure.
Are women who have twins more fertile? While previous studies concluded they are, a detailed analysis of more than 100,000 births from pre-industrial Europe by an international team of scientists shows they are not.
An FDA-approved drug to lower blood sugar in adults with Type 2 diabetes also may decrease blood vessel dysfunction associated with aging, according to a new study from the University of Missouri School of Medicine.
When administered soon after the onset of acute ischemic stroke, current approved treatments for the condition can dramatically improve patient outcomes.
Scientists at Yale Cancer Center have found that patients with breast cancer and high levels of insulin in the blood may be responsive to metabolism-targeting treatments, which in turn may improve the effectiveness of subsequent chemotherapy treatments.
The chronic nutritional and metabolic disease of obesity is characterized by an excessive increase in body fat and its accumulation in tissues.
When it comes to avian influenza, more commonly known as bird flu, all birds are not created equal.
A new study authored by Sambhawa Priya and other researchers offers a detailed look at the interactions between the gut microbiome of humans in health and disease.
Yeasts have been evolving and diversifying for more than 400 million years. Likely, symbiotic relationships between humans and yeasts started already at the origin of our species (200-300 thousand years ago).
Human beings, like most organisms, are constantly exposed to alternating colder or warmer temperatures.
In a recent study published in the Proceedings of the National Academy of Sciences journal, researchers assessed the efficiency of a novel intranasal and injectable therapy in improving life expectancy.
In a recent study published in the journal Science, researchers created an atlas termed the Tabula sapiens for over 400 distinct cell types of humans. Several aspects of human physiology were revealed by the atlas, such as how different types of cells splice genes differently.
Exercise increases levels of a chemical involved in brain cell growth, which bolsters the release of the "feel good" hormone dopamine, a new study shows. Dopamine is known to play a key role in movement, motivation, and learning.
People with Parkinson's disease and their doctors confront many unknowns, including the answer to exactly how deep brain stimulation (DBS) relieves some of the motor symptoms patients experience.
