Health & Medicine

The study of the human mind and body, how these function, and how they interact—not only with each other but also with their environment—has been of utmost importance in ensuring human well-being. Research on potential treatments and preventive medicine has expanded greatly with the development of modern medicine, and a network of disciplines, including such fields as genetics, psychology, and nutrition, aims to facilitate the betterment of our health.

human body; human anatomy Anatomy & Physiology
Human beings have long been curious about the way that things work, and that curiosity includes wondering about how we ourselves work. The fields of anatomy and physiology involve studying the structures of bodies and the way that those structures and bodies function.

The Barr, or sex chromatin, body is an inactive X chromosome. It appears as a dense, dark-staining spot at the periphery of the nucleus of each somatic cell in the human female. Conditions & Diseases
Whether we like it or not, living things are susceptible to any number of illnesses and conditions that can threaten or harm the health of those afflicted. Bacteria, viruses, and other microbiological agents are obvious challenges to health. Human disease may be acute, chronic, malignant, or benign, and it is usually indicated by signs and symptoms such as fever or vomiting. Additionally, diseases may be communicable (contagious) or noncommunicable; of the latter, the four major types identified by the World Health Organization are cancer, cardiovascular disease, chronic respiratory disease, and diabetes mellitus.

A light gray peppered moth (Biston betularia) and a darkly pigmented variant rest near each other on the trunk of a soot-covered oak tree. Against this background, the light gray moth is more easily noticed than the darker variant. Genetics & Evolution
The plants and animals that are so familiar to us here on Earth today may have been harder to spot millions of years ago. The theory of evolution, one of the keystones of modern biological theory, is based on the idea that living things on Earth can be traced back to other preexisting types and that the differences are due to modifications that occurred over successive generations. Genetics, an essential part of the study of evolution, looks at the inheritance of characteristics by children from their parents. It can help explain how you got your mom's green eyes or why your hair is red even though your parents are brunettes.

Vegetables are an important part of a balanced diet. Health, Nutrition & Fitness
Health isn't just about being able to impress people at the gym with your weight-lifting prowess. Physical fitness, the body's ability to function properly, and the absence of disease are important factors in determining health, as is one's emotional, mental, and social state. In addition, nutrition provides the energy that fuels all physical and mental activities, including the aforementioned displays of weight-lifting mastery.

subcategory placeholder Human Development
Even if you feel like a kid at heart, you probably still went through (or are currently undergoing) the typical process of change and growth that takes place between human infancy and maturity. After birth, human beings undergo infant and toddler development, moving on to child development before progressing to puberty and adolescence on the way to adulthood. Human growth involves not only biological development—the progressive changes in size, shape, and function during the life of an organism—but also emotional and psychological development.

laparoscopy Medicine
From prehistoric times onward, humans have sought to find cures for the ailments and injuries that befall them. This has led to a long history of diverse attempted treatments, including herbal remedies, leeching, hydrotherapy, acupuncture, homeopathy, and more, all the way up to the most recent treatments that have come into use during the development of today's modern medicine. Medical research and the study of the causes of disease (pathology) have led to rapid and significant advances in medicine, improving both the efficacy of treatments and our understanding of illnesses and how they operate. The importance of preventive medicine has grown, and the field of medicine has become increasingly specialized as medical disciplines and branches such as endocrinology, immunology, psychiatry, radiology, epidemiology, and nanomedicine have emerged.
Articles
subcategory placeholder Psychology & Mental Health
Although Sigmund Freud was once one of the most recognizable faces of psychology, this scientific discipline has developed significantly since the time of his predominance. Psychology has become an increasingly integrative science at the hub of diverse other disciplines, from biology and neurology to sociology, anthropology, and economics. At the same time, old sub-disciplinary boundaries within pyschology itself are now crossed more freely; interdisciplinary teams may work on a common problem using methods that draw on multiple levels of analysis, whether social, cognitive, or biological.
