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.
The results of a new research showed that many of the genes that are expressed by microglia are different between humans and mice, which are frequently used as animal models in research on Alzheimer's disease and other neurodegenerative disorders.
Scientists have used magnetism to activate tiny groups of cells in the brain, inducing bodily movements that include running, rotating and losing control of the extremities -- an achievement that could lead to advances in studying and treating neurological disease.
Scientists at the University of Oxford and the University of Bristol have developed a new method to 3D-print laboratory- grown cells to form living structures.
Researchers at Baylor College of Medicine have shed light on the process that guides the maturation of newborn muscles into adult, fully functional organs.
During the "Novel Implications for Blood Flow and Vascular Dysfunction in Non-cardiovascular Related Disease" symposium at the APS Cardiovascular Aging: New Frontiers and Old Friends conference, researchers will present findings that emphasize the interaction between age-related cardiovascular dysfunction and disease whose risk increases with age.
An estimated 1 in 3 U.S. adults have high blood pressure. Blood pressure levels are often assessed by using automatic blood pressure devices.
High physical fitness is known to be related to enhanced blood vessel dilation and blood flow (endothelial function) in aging men.
A new study suggests that a single exposure to e-cigarette (e-cig) vapor may be enough to impair vascular function.
Heart disease remains the leading cause of death in the U.S. and growing older is the greatest- and most inevitable- risk factor for it.
UCLA scientists report the first evidence that a gene outside the brain controls the ability to rebound from sleep deprivation -- a surprising discovery that could eventually lead to greatly improved treatments for insomnia and other sleep disorders that do not involve getting a drug into the brain.
Millions of people die every year from dehydration as a result of exposure and illness. In humans, even the most minor dehydration can compromise the kidneys causing lifelong, irreparable issues or even death.
Age-related frailty may be a treatable and preventable health problem, just like obesity, diabetes, and cardiovascular disease, highlights a review in Frontiers in Physiology.
Two researchers have been awarded grants that could help uncover the next breakthrough in heart-health research, the American Heart Association and The Paul G. Allen Frontiers Group announced Wednesday.
Scientists report in a new study that by imitating a natural process of cells, they prevented the formation of protein clumps associated with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia.
A first-of-its kind payment formula developed at the University of Massachusetts Medical School recommends allocating some health insurance dollars for patients in vulnerable communities and for those subject to social risks, in addition to their medical issues.
The Society of Nuclear Medicine and Molecular Imaging (SNMMI), an international scientific and medical organization, recognized contributions to the field of nuclear medicine and molecular imaging during its 2017 Annual Meeting in Denver, Colorado. Several awards ceremonies were held to recognize the valuable role SNMMI members play in advancing the diagnosis and treatment of heart disease, cancer and neurological conditions.
Restricting how much you eat without starving has been shown to robustly extend lifespan in more than 20 species of animals including primates.
Fresh thyme and oregano offer a savory touch to a tasty dish, but a University of Iowa researcher recently discovered natural compounds in the herbs that may offer a treatment for cachexia or "wasting syndrome" as it is more commonly known.
Researchers from the University of Chicago Medicine have received a five-year, $1.8 million grant, from the U.S. Department of Health and Human Services Office of Minority Health to develop a program that could help improve diabetes care for low-income racial and ethnic minority patients.
During the millions of pregnancies that occur in the United States every year, expectant moms learn oodles about their developing fetuses over months of gestation.
