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.
Cancer-related fatigue (CRF) is a debilitating yet all-too-common condition, which can severely affect quality of life for patients undergoing treatment.
The human lymphatic system consists of a vast network of vessels that drain protein-rich fluid in tissues and transport it to lymph nodes.
A study in Nature Communications delves into how the liver's circadian clock responds to meal timing, impacting fat metabolism and other bodily processes. The research underscores the intricate network that contributes to liver's diurnal rhythms, regulated by protein phosphorylation and nutrient availability.
Researchers from the University of Pittsburgh and the National Institutes of Health (NIH) Vaccine Research Center have developed an improved way to test potential vaccines against bird flu. The report was published this week in the journal iScience.
Researchers used Camponotus fellah (carpenter ants) as a model species to perform behavioral tracking and ribonucleic acid-sequencing (RNA-seq) to study the transcriptome-level differences between socially isolated workers versus workers in groups.
Driven by changing estrogen levels, the menopause transition has a major influence on physiology during aging.
Researchers used an interdisciplinary approach incorporating phylogenetics, 3D protein modeling, and plasmid design to identify and computationally design an antigen representing the core of most currently known sarbecoviruses.
The vagus nerve, known for its role in 'resting and digesting', has now been found to have an important role in exercise, helping the heart pump blood, which delivers oxygen around the body.
Educational programs that promote mental and physical health can help young people - particularly in environments of chronic stress and trauma exposure - learn healthy coping strategies, avoid risky behaviors, and succeed in school.
The complex relationship between physical activity and energy balance – food intake versus energy expenditure – is still a challenge for science, especially in light of the rising worldwide prevalence of overweight and obesity
Researchers at the University of Michigan have developed a model for studying one type of familial epilepsy, opening the door to understanding—and eventually targeting—the mechanisms that lead to the disorder and its associated fatalities.
Researchers have developed a wearable optical device for early detection of hemorrhage during labor or after childbirth.
Researchers have shown in a mouse model and lab cultures that a compound derived from hops reduces the abundance of a gut bacterium associated with metabolic syndrome.
Psychological loss can occur when someone loses a job, loses a sense of control or safety or when a spouse dies.
A new paper explores how PMDs affect the time of menopause and the severity of vasomotor menopausal symptoms like hot flashes.
To test new stroke treatments, a research team from the Keck School of Medicine of USC develops a more rigorous system for conducting preclinical research that could lead to more successful clinical trials.
Hearing the sound of a newborn's wail can trigger the release of oxytocin, a brain chemical that controls breast milk release in mothers, a new study in rodents shows.
The Eunice Kennedy Shriver National Institute of Child Health and Human Development awarded $3.1 million to the University of Arkansas to study a spectrum of pediatric mitochondrial disorders caused by mutations in the mitochondria.
Prof. John Speakman from the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences, alongside Prof. Kevin Hall from the National Institutes of Health (U.S.), Prof. Thorkild Sorensen from the University of Copenhagen and Prof. David Allison from Indiana University (U.S.), has published a perspective article on potential mechanisms of obesity pathogenesis.
A new Northwestern Medicine study challenges a common belief in what triggers Parkinson's disease.
