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.
Certain parts of our body, such as the skin or liver, can repair themselves after a damage. Known as cell regeneration, this phenomenon describes how cells that are still functional start to proliferate to compensate for the loss.
Rank in social hierarchy is a condition not solely claimed by humans. In the animal kingdom, male peacocks exhibit brightly colored plumes to illustrate dominance, and underwater, male fish show pops of bright colors to do the same.
Scientists at the University of Virginia School of Medicine have developed a method to understand how HIV and other viruses first begin to infect our cells, and that could help us prevent COVID-19 and other diseases.
Public health agencies across the UK should launch a National Covid-19 Resilience Programme to support older people through the pandemic and to keep them healthy and resilient over the winter - that's the recommendation from a leading group of scientists and clinicians working in the fields of physiology, nutrition and physiotherapy.
Researchers at the University of São Paulo (USP) in Brazil have shown for the first time that stimulating expression of a protein naturally produced by the human body can be a strategy to combat loss of skeletal muscle mass, which happens normally with aging but can intensify in cases of neurodegenerative or inflammatory disease, or in patients who spend long periods in intensive care units (ICUs).
It appears that autophagy protects our neurons in the brain, but evidently for entirely different reasons than previously assumed, as researchers from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) and Charité in Berlin have now shown.
University of Illinois Urbana-Champaign Professor of Molecular and Integrative Physiology Erik Nelson has won a $4.5M Era of Hope Scholar Award from the United States Department of Defense (DoD) Breast Cancer Research Program (BCRP).
Regular training enhances your strength, but recovery is equally important. Elastic bandages and compression garments are widely used in sports to facilitate recovery and prevent injuries.
Before the first Virgin Hyperloop ride takes off, the brains behind pioneering neuroscience research at West Virginia University will help ensure the health and well-being of its passengers and operators.
Researchers discover that a specialized part of the chromosomes, essential for a correct cell division, is smaller and weaker in stem cells, when compared to the ones of differentiated cells.
In the nearly two centuries since German physician Carl Wunderlich established 98.6°F as the standard "normal" body temperature, it has been used by parents and doctors alike as the measure by which fevers -- and often the severity of illness -- have been assessed.
A new observational study by Swedish researchers shows a significant decline in death rates among hospitalized patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Their study titled, "Decline in mortality among hospitalized covid-19 patients in Sweden: a nationwide observational study," was released online as a preprint on the medRxiv* server.
Research at Washington State University sheds new light on one molecule that may be used to treat a heart condition that can lead to stroke, heart attack and other forms of heart disease.
A new study from Lawson Health Research Institute, Western University and University of Alberta suggests that COVID-19 affects the human body's blood concentration levels of specific metabolites - small molecules broken down in the human body through the process of metabolism.
A new study by researchers at UC Santa Cruz shows how a genetic mutation throws off the timing of the biological clock, causing a common sleep syndrome called delayed sleep phase disorder.
MicroRNAs (miRNAs) are evolutionarily conserved small noncoding RNAs - bits of genetic code that serve as critical gene regulators in many aspects of biological processes important for human health.
To identify new potential therapeutic targets for SARS-CoV-2, a team of scientists at the New York Genome Center, New York University, and the Icahn School of Medicine at Mount Sinai, performed a genome-scale, loss-of-function CRISPR screen to systematically knockout all genes in the human genome.
University of North Carolina School of Medicine scientists has made a curious discovery about a well-known human protein that helps the immune system fight viral infections.
Research from Saint Louis University finds that high fat or "ketogenic" diets could completely prevent, or even reverse heart failure caused by a metabolic process.
Exposure to higher air pollution levels and greater population density during the early months of life may be associated with an increase in children's body mass index (BMI).
