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.
Brain networks responsible for sensing, understanding, and responding emotionally to pain develop at different rates in infants, with the conscious understanding of pain not fully developed until after birth, finds a new study led by UCL (University College London) researchers.
Early nutritional and antibiotic exposures affect adult gut microbiota, with genetic background and parent-of-origin significantly influencing outcomes.
The kidney, a critical organ for waste filtration and fluid regulation, is the subject of a groundbreaking molecular mapping project that could reshape our understanding of renal health.
A new Concordia study suggests that aquatic therapy for individuals with chronic low back pain can do more than strengthen the muscles around the spine.
Bone growth occurs through the proliferation of specialized cells of the cartilage tissue, known as chondrocytes, on either end of a bone.
Six out of ten people with type 2 diabetes had fatty liver in a new study from Linköping University. Of these, only a small percentage had developed more severe liver disease.
City of Hope®, one of the largest and most advanced cancer research and treatment organizations in the U.S. with its National Medical Center named top 5 in the nation for cancer by U.S. News & World Report, co-led the first study to demonstrate that characterizing genetic material near chromosomes forecasts how mutated, cancer-causing genes reengineer DNA and alter the tumor microenvironment.
High-resolution digital tracking reveals how daily habits, meal timing, sleep, and physical activity shape metabolic risk for type 2 diabetes. Meal timing, sleep patterns, and activity windows each play distinct roles in insulin resistance and glucose control.
Thanks to lab-grown miniature intestines, researchers at Uppsala University have successfully mapped how aggressive Shigella bacteria infect the human gut.
When the amount of cholesterol in the blood is too high, hypercholesterolemia can develop, causing serious damage to the arteries and cardiovascular health.
In a revealing Genomic Press Interview published today in Brain Medicine, Sara Poletti, PhD, senior researcher at IRCCS Ospedale San Raffaele Milan, illuminates the profound connections between childhood adversity and lifelong vulnerability to psychiatric disorders through persistent neuroinflammation pathways and alterations in brain structure.
New technology that allows a University of Virginia-developed artificial pancreas system to adapt to users' changing bodies – and lets users test changes to how the system operates – improved control of their type 1 diabetes, a study has found.
Cocaine, a drug of abuse, activates just a portion - 10 to 20 percent - of the neurons in the brain's nucleus accumbens, a critical region linked to motivation and addiction.
Conventional transcriptomic techniques have revealed much about gene expression at the population and single-cell level—but they overlook one crucial factor: spatial context.
A new study from The University of Texas at Arlington details a novel strategy for how the body clears out dead cells during stress, revealing unexpected roles for well-known stress-response genes-a discovery that could help scientists better understand diseases affecting the immune system, brain and metabolism.
The Hybrid Heart, a soft robotic total artificial heart, offers a breakthrough in treating end-stage heart failure with improved biocompatibility and function.
Using an algorithm they call the Krakencoder, researchers at Weill Cornell Medicine are a step closer to unraveling how the brain's wiring supports the way we think and act.
Low back pain is the most prevalent musculoskeletal condition worldwide and is closely tied to the progressive degeneration of intervertebral discs.
Eating a high-fat diet containing a large amount of oleic acid – a type of fatty acid commonly found in olive oil – could drive obesity more than other types of dietary fats, according to a study published in the journal Cell Reports.
A team at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), led by Jorge Alegre-Cebollada, has developed an innovative method, called TEVs-TTN, for studying the specific mechanical functions of proteins through their controlled cleavage, a process that renders the proteins unable to sense and transmit mechanical force.
