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.

New Approach Aims to Make CRISPR Therapy Safer and More Effective

CRISPR is a powerful gene-editing tool that holds enormous potential for treating genetic diseases by allowing scientists to cut, replace, or delete mutations in DNA.

Study Reveals Key Ion Channel in Extracellular Vesicles for Cargo Transport

Scientists have revealed the secret to the structural integrity of tiny particles that transport cargo from cell to cell through blood vessels and bodily fluids: special proteins that keep their membranes intact as they negotiate shifting electrical impulses in different biological environments.

New Discovery Sheds Light on How Monoamines Regulate Brain Rhythms

A collaborative effort between Mount Sinai and Memorial Sloan Kettering Cancer Center has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-packaging proteins of our cells.
