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 at Weill Cornell Medicine have developed a computational technique that greatly increases the resolution of atomic force microscopy, a specialized type of microscope that "feels" the atoms at a surface.
Stimulation of the nervous system with neurotechnology has opened up new avenues for treating human disorders, such as prosthetic arms and legs that restore the sense of touch in amputees, prosthetic fingertips that provide detailed sensory feedback with varying touch resolution, and intraneural stimulation to help the blind by giving sensations of sight.
In a new publication from Cardiovascular Innovations and Applications; Sharen Lee, Gary Tse, Xin Wang, Adrian Baranchuk and Tong Liu from Laboratory of Cardiovascular Physiology, Hong Kong, China, Second Hospital of Tianjin Medical University, Tianjin, China and Queen's University, Kingston, Ontario, Canada consider ST-segment depression in leads I and aVL.
Getting energy and nutrients from the environment - that is, eating - is such an important function that it has been regulated through sophisticated mechanisms over hundreds of millions of years. Some of these mechanisms are only now beginning to be unraveled.
Spectacular images of a molecule that shuttles omega-3 fatty acids into the brain may open a doorway for delivering neurological therapeutics to the brain.
How does human life begin, which processes influence the human gut microbiome, and what do researchers know about the collective intelligence of honeybees? Members of the German National Academy of Sciences Leopoldina will answer these and other questions at the virtual symposium of Class II - Life Sciences.
The Southwest National Primate Research Center at Texas Biomedical Research Institute has been awarded more than $37 million from the National Institutes of Health to continue operations into 2026.
Changes to gut microbiome are known to impact metabolic health. Physiologists at Laval University in Canada have discovered that diets containing low fiber and high fat cause significant shifts in the gut microbiome-;the collection of bacteria, viruses, fungi and other multicellular microorganisms that live in the gastrointestinal system.
Women exposed to higher levels of air pollution during pregnancy have babies who grow unusually fast in the first months after birth, putting on excess fat that puts them at risk of obesity and related diseases later in life, new CU Boulder research shows.
Nearly 12,000 people in Sweden received sickness benefit from the Swedish Social Insurance Agency for COVID-19 during the first wave of the pandemic.
Like amyloid plaque, the genetic variant APOE4 has long been associated with Alzheimer's disease, but still little is known about the role the gene plays in the disease process.
A plant-based diet appears to afford significant protection to rats bred to become hypertensive on a high-salt diet, scientists report. When the rats become pregnant, the whole grain diet also protects the mothers and their offspring from deadly preeclampsia.
Calcified Tissue International and Musculoskeletal Research is among the leading peer-reviewed journals publishing original preclinical, translational, and clinical research as well as expert reviews in the bone and musculoskeletal field.
The 30,000 or so genes making up the human genome contain the instructions vital to life. Yet each of our cells expresses only a subset of these genes in their daily functioning. The difference between a heart cell and a liver cell, for example, is determined by which genes are expressed--and the correct expression of genes can mean the difference between health and disease.
Journal of Cell Biology (JCB), Journal of Experimental Medicine (JEM), and Journal of General Physiology (JGP) announce an editorial policy allowing swift and confidential updates to author names at any time and for any reason including changes to gender identity, marriage, divorce, religion, or other personal circumstances.
Most people listen to music throughout their day and often near bedtime to wind down. But can that actually cause your sleep to suffer? When sleep researcher Michael Scullin, Ph.D., associate professor of psychology and neuroscience at Baylor University, realized he was waking in the middle of the night with a song stuck in his head, he saw an opportunity to study how music -- and particularly stuck songs -- might affect sleep patterns.
New findings from the University of Minnesota Medical School are helping uncover why some people are more likely to be overweight and develop Type 2 diabetes -- and it starts in the womb.
Bedfont presents its new Hydrogen and Methane Breath Testing Home Kits in association with GI Cognition.
A cell-penetrating peptide developed by researchers at Vanderbilt University Medical Center can prevent, in an animal model, the often-fatal septic shock that can result from bacterial and viral infections.
Women who will develop potentially life-threatening disorders during pregnancy can be identified early when hormone levels in the placenta are tested, a new study has shown.
