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.
Scientists from Russia and Switzerland have probed into nanostructures covering the corneas of the eyes of small fruit flies. Investigating them the team learned how to produce the safe biodegradable nanocoating with antimicrobial, anti-reflective, and self-cleaning properties in a cost-effective and eco-friendly way.
In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals -; dopamine and serotonin -; are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.
Scientists at Wake Forest School of Medicine have recorded real time changes in dopamine and serotonin levels in the human brain that are involved with perception and decision-making.
With a nearly $2.6 million grant from the National Institutes of Health, Michigan State University researchers are using nanoscopic particles to turn the body's own cells into weapons that cancer won't see coming.
Human spaceflight has been fascinating man for centuries, representing the intangible need to explore the unknown, challenge new frontiers, advance technology and push scientific boundaries further.
Researchers might be able to treat a troublesome cough in disease without disrupting the protective cough we need for optimal lung health, by targeting the different brain circuits involved. That's according to new research published this week in The Journal of Physiology.
N-acetylglucosamine, a simple sugar found in human breast milk and sold as an over-the-counter dietary supplement in the United States, promotes myelin repair in mouse models and correlates with myelination levels in multiple sclerosis patients according to a new University of California, Irvine-led study.
A novel study shows that facemask use does not affect indicators of cognitive performance when the wearers are resting or performing moderate physical work in hot environments.
Since the outset of the COVID-19 pandemic, there has been much debate about the danger to hospital staff from anaesthetic procedures. Concerns include that placing a tube in the patient's airway (intubation) before surgery or removing it at the end (extubation) may produce a fine mist of small particles (called aerosols) and spread the COVID-19 virus to nearby staff.
Researchers from the University of Iowa may have discovered a safe new way to manage blood sugar non-invasively. Exposing diabetic mice to a combination of static electric and magnetic fields for a few hours per day normalizes two major hallmarks of type 2 diabetes, according to new findings published Oct. 6 in Cell Metabolism.
Oni Basu, PhD, an assistant professor of genetic medicine at the University of Chicago, has received the prestigious National Institutes of Health Director's New Innovator Award.
A University of Houston biomedical researcher is developing new technology that will measure the stiffness of the lens in the eye, which is likely associated with presbyopia, or farsightedness, the inevitable and age-related loss of the ability to focus on nearby objects.
A Purdue University team has developed a novel testing platform to evaluate how breast cancer cells respond to the recurrent stretching that occurs in the lungs during breathing.
Requirements for electronic health records are greater now than ever, and that burden is exacerbating the problem of physician burnout. However, there might be a solution: the medical scribe.
Tissues and cells in the human body are subjected to a constant push and pull - strained by other cells, blood pressure and fluid flow, to name a few.
A recent publication in the Journal of Neuroscience by a group of researchers at the University of Kentucky looks at Encoding the Odor of Cigarette Smoke. Tim McClintock, a physiology professor at UK, says their work lays a foundation for two things.
In a new study, published in Current Biology, researchers from the University of California, Irvine School of Medicine reveal how subanesthetic ketamine, which is used for pain management and as an antidepressant in humans, is effective in treating adult amblyopia, a brain disorder commonly known as "lazy eye."
The use of isokinetic dynamometers with older adults extends far beyond orthopedics, but the reliability and responsiveness of isokinetic measures in conditions like COPD and stroke are still being evaluated, report experts in Isokinetics and Exercise Science.
Cancer chemotherapy changes the function of cells that repair heart injury, researchers at The University of Texas Health Science Center at San Antonio (UT Health San Antonio) discovered.
Our ability to regulate body temperature and keep our bodies from becoming dehydrated declines as we get older. New research published today in The Journal of Physiology improves our understanding of the relation between temperature regulation and dehydration.
