Biology Articles » Anatomy & Physiology
This section includes articles on Anatomy, which deals with the structure and organization of living things at the cellular, tissue, and organ level, and Physiology, which studies the mechanical, physical, and biochemical functions of living organisms. It is not uncommon for Physiology to be associated with Anatomy since structure and function are mostly inseparable topics particularly at the cellular and molecular level.
Tarantula venom and chili peppers target same pain sensorVenom from a West Indian tarantula has been shown to cause pain by exciting the same nerve cells in mice that sense high temperatures and the hot, spicy ingredient in chili peppers.
Molecular anatomy of influenza virus detailedScientists have succeeded in imaging, in unprecedented detail, the virus that causes influenza.
Cellular composition and ultrastructure of the gill epithelium of larval and adult lampreys : Implications for osmoregulation in fresh and seawaterThe ultrastructural characteristics of each of the cell types present in the gill epithelium at the different stages in the life cycle of lampreys are described.
Heterogeneity of the intrahepatic biliary epitheliumA review of the recent findings related to the morphological heterogeneity of the biliary epithelium and the heterogeneous pathophysiological responses of different sized bile ducts to liver gastrointestinal hormones and peptides and liver injury/toxins
Cholangiocytes and blood supplyA review of the recent studies related to the physiopathology of hepatic microvasculature in experimental models of liver damage and its biological and clinical implications.
Bile acid interactions with cholangiocytesThe review will outline mechanisms for bile acid transport in cholangiocytes, the role of bile acid regulation of cholangiocyte proliferation, secretion and apoptosis in animal models and human diseases.
Vocal cords deserve the applauseThe vocal cords are twin folds of throat muscle stretched horizontally across the voice box, or larynx.
The gallbladder: The digestive holding tankThe gallbladder is a holding tank for bile, the body's digestive detergent.
Hard Hearts: New Discovery of Bone in Heart Tissue May Explain Valve DiseaseNews: Researchers have confirmed that bone -- similar to that found in the human skeleton -- is present in a substantial portion of diseased heart valves.
The hair cycleA summary of the major events of the hair cycle, and known regulators of the transitions.
Fibroblast heterogeneity: more than skin deepThe article reviews the fibroblasts on normal adult human skin wherein at least three distinct subpopulations of fibroblasts exist...
Smooth Muscle Contraction and RelaxationThis brief review serves as a refresher on smooth muscle physiology for those educators who teach in medical and graduate courses of physiology. Additionally, those professionals who are in need of an update on smooth muscle physiology may find this revie
Nothing but skin and boneThis review discussed the various facets of 2 diverse, yet interdependent, tissues: the skin and bone.
The stem cell niches in boneIn this review the authors compared the architecture of the 2 HSC niches in bone marrow, and highlighted the function of osteoblasts in maintaining a quiescent HSC microenvironment....
Feeling Nauseous? Research Suggests Your Brain Plays A RoleResearchers have found that a chemical produced by the immune system directly stimulates the part of the brain that controls digestion.
Transplanted Skeletal Muscle Mimics Heart Muscle; Helps Failing Heart Pump, Duke Researchers SayImmature muscle cells transplanted from the leg of an animal to its heart apparently can "learn" to act like heart muscle, researchers found...
Why The Heart Stops Pumping: Researchers Identify Cellular-Molecular Defect In Heart FailureUntreated high blood pressure underlies much cardiovascular disease, including enlargement of the heart, heart failure, arrhythmias and stroke.
Regeneration of inner ear cells 'could prevent deafness'Evidence that the workings of the inner ear can be regenerated to treat a common cause of deafness is published today.
