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.
Combining seizure-preventing electrical stimulation with repetitive musical tones improves processing of sounds in the brain, according to new research.
Scientists have developed an automated tool for mapping the movement of particles inside cells that may accelerate research in many fields, a new study in eLife reports.
In the human body the salt content of cells and their surrounding is regulated by sophisticated transport systems.
On average, the human heart beats anywhere from 60 to 80 times per minute - that's almost 42 million times a year. Each beat consists of billions of cells working together, using their protein channels to pass electrical signals across the muscle.
When we race walk, for example, part of our healthy heart muscle may want a little more blood and oxygen, so our tiniest blood vessels send a message upstream to the larger vessels to send more.
Scientists of South Ural State University are studying enzymes that can break down stress hormones. They are also finding a way to regulate the activity of these enzymes. It will help to cure diseases caused by stress.
Researchers at the Max Delbrueck Center for Molecular Medicine have identified an epigenetic mechanism that appears to strongly influence healthy aging.
Lack of sleep can be dangerous; it is thought to play a role in up to 30% of all motor vehicle crashes and even implicated in catastrophic events, such as the Chernobyl nuclear disaster.
Researchers from TARA Biosystems, Inc. and GlaxoSmithKline today published data demonstrating that TARA's engineered heart-on-a-chip system replicated drug responses found in adult humans.
Researchers at Tel Aviv University have developed a novel nano-vaccine for melanoma, the most aggressive type of skin cancer.
Air pollution is made up of both gaseous and particulate matter. Each year almost two million people die as a direct result of air pollution with many more experiencing impaired lung function, developing lung diseases such as asthma and chronic obstructive pulmonary disease.
Neuroscientists at the University of Sussex have revealed that complex movements, such as those that maintain our posture, can be controlled by a simple genetic system, providing a framework to better understand the molecular basis of diseases that affect motor control, like Huntington's and Parkinson's.
The system connects the arteries to the veins. There are 100,000 miles of blood vessels in the adult human body.
An IMAS-led study of seabirds that had ingested plastic debris has revealed a range of non-lethal impacts on their health and physiology.
New research suggests exercise may prevent or lessen artery stiffening associated with heart failure by limiting the buildup of unsafe chemicals around the heart.
Researchers at the Center for BrainHealth, part of The University of Texas at Dallas, in collaboration with a team from UT Southwestern, have developed technology for a novel diagnostic method for multiple sclerosis.
A startling new study shows that cells that are exquisitely sensitive to oxytocin are found in a tiny region in the brains of female but not male mice. This could be of great importance in explaining maternal behavior in females and eventually in treating social disorders like postpartum depression and autism spectrum disorder.
Fatty liver disease is often associated with alcoholism, but more than a third of Americans have fatty livers despite moderate or absent alcohol consumption.
Scientists have uncovered the molecular action through which the herb cilantro delays the onset of certain seizures in epilepsy and other diseases.
Researchers have found that severe malnutrition is associated with lower exposure to the antimalarial drug lumefantrine in children treated with artemether-lumefantrine, the most common treatment, for uncomplicated falciparum malaria.
