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.
Specific cells in the retina trigger inflammation and vision impairment associated with diabetes, according to new research out of Case Western Reserve University School of Medicine.
Researchers from the Higher School of Economics, Ecole Normale Supérieure, Paris, Indiana University and the Russian Academy of Sciences Nizhny Novgorod Institute of Applied Physics have identified potential alcoholism mechanisms, associated with altered dopaminergic neuron response to complex dynamics of prefrontal cortex neurones affecting dopamine release.
Researchers have been able to demonstrate the hereditary nature of certain forms of tinnitus. Bilateral tinnitus - that is, tinnitus in both ears - has been shown to depend on genetic factors, particularly in men.
A new study finds that caffeine may protect the lungs from damage caused by prolonged oxygen therapy, such as oxygen supplementation given to premature babies.
A hormone secreted by bone cells can suppress appetite, according to mouse studies conducted by Columbia University Medical Center researchers.
A research team led by scientists from Brigham and Women's Hospital has developed a novel technology platform that enables the continuous and automated monitoring of so-called "organs-on-chips" -- tiny devices that incorporate living cells to mimic the biology of bona fide human organs.
A heart beat begins with a rush of calcium into the heart cell followed by a burst of energy from the resident mitochondria. These two events occur with each beat.
Drinking concentrated blueberry juice improves brain function in older people, according to research by the University of Exeter.
Nerve cells in our brains work together in harmony to store and retrieve short-term memory, and are not solo artists as previously thought, Western-led brain research has determined.
Head injuries can harm hundreds of genes in the brain in a way that increases people's risk for a wide range of neurological and psychiatric disorders, UCLA life scientists report.
There has long been interest in whether monoamine oxidase type B (MAO-B) inhibitors slow progression of Parkinson's disease (PD) and improve long-term outcomes.
In a paper published in Biochemical Pharmacology, Saint Louis University researchers examined the way a nuclear receptor called REV-ERB is involved in regulating cholesterol metabolism.
The kind of research I'm interested in is a technique called diffusion MRI and this technique is sensitive to the microstructure of the tissue. Particular clinical applications that it is used for are cancer and looking at neurodegenerative diseases.
Specialized nerve cells, known as somatostatin-expressing (Sst) interneurons, in the outer part of the mammalian brain (or cerebral cortex) — play a key role in controlling how information flows in the brain when it is awake and alert.
A Michigan State University researcher has received a $1.65 million grant that looks to bring a better understanding about fertility treatments in women by studying the effect of hormones on ovulation and reproduction in cows.
Researchers at Karolinska Institutet and KTH Royal Institute of Technology in Sweden have contributed to a recent discovery that the heart is filled with the aid of hydraulic forces, the same as those involved in hydraulic brakes in cars.
Optogenetics is a way of introducing information into the brain using light, it targets specific cells or connections across the brain. It is fast, like brain signaling, and helps you communicate with neural circuitry in a language more similar to what is normally used within the brain.
Scientific evidence that the assortment of gut microbes in humans influences different and critical aspects of health is piling up: Researchers think our microbes may influence obesity, anxiety, depression, autism, cancer and gastrointestinal diseases.
People with intermittent explosive disorder—a condition marked by frequent physical or verbal outbursts—are at five times greater risk for abusing substances such as alcohol, tobacco and marijuana than those who don't display frequent aggressive behavior, according to a new study by researchers from the University of Chicago.
Scientists at the Institute for Infectious Diseases, University of Bern have developed an in vitro stem cell-based bioassay grown on multi-electrode arrays capable of detecting the biological activity of Clostridium botulinum neurotoxins.
