General concepts

Anatomy – study of the physical structure of organisms. In contrast to macroscopic or gross anatomy, cytology and histology are concerned with microscopic structures.
Biochemistry – study of the chemistry taking place in living organisms, especially the structure and function of their chemical components.
Biostatistics – application of statistics to biological fields in the broadest sense. A knowledge of biostatistics is essential in the planning, evaluation, and interpretation of medical research. It is also fundamental to epidemiology and evidence-based medicine.
Cytology – microscopic study of individual cells.
Embryology – study of the early development of organisms.
Epidemiology – study of the demographics of disease processes, and includes, but is not limited to, the study of epidemics.
Genetics – study of genes, and their role in biological inheritance.
Histology – study of the structures of biological tissues by light microscopy, electron microscopy and immunohistochemistry.
Immunology – study of the immune system, which includes the innate and adaptive immune system in humans, for example.
Microbiology – study of microorganisms, including protozoa, bacteria, fungi, and viruses.
Neuroscience includes those disciplines of science that are related to the study of the nervous system. A main focus of neuroscience is the biology and physiology of the human brain and spinal cord.
Nutrition – study of the relationship of food and drink to health and disease, especially in determining an optimal diet. Medical nutrition therapy is done by dietitians and is prescribed for diabetes, cardiovascular diseases, weight and eating disorders, allergies, malnutrition, and neoplastic diseases.
Pathology as a science – study of disease–the causes, course, progression and resolution thereof.
Pharmacology – study of drugs and their actions.
