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.

Researchers unmask functioning of protein involved in DNA repair during spermatogenesis

Researchers from the Department of Cell Biology, Physiology and Immunology and the Institute for Biotechnology and Biomedicine of the Universitat Autònoma de Barcelona have unmasked the functioning of a protein involved in DNA repair, ATR, in the meiotic recombination process which takes place during the development of spermatocytes - sperm precursor cells- and how inhibiting this protein causes anomalies which block spermatogenesis.

Researchers focus on mechanisms involved in development of non-alcoholic fatty liver disease

One of the lines of research of the UPV/EHU's Lipids & Liver group, which focusses on the mechanisms involved in the development and progression of non-alcoholic fatty liver disease, is achieving significant advances in a range of aspects; these include the identification of proteins that alter the metabolic pathways in the development and progression of liver disease, and even cancer, and the seeking of targets to enable the disease to be reversed.

Natural selection may have influence on personalities, suggests study

For more than a century, scientists have understood that natural selection have profound effects on how an animal looks - Anolis lizards that spend more time on the ground, for example, might need longer legs for running, while species that remain in the trees usually have shorter legs better suited for climbing.
