Branches of Medicine: Know the Most Important Branches of This Extraordinary Science

As a career you have a variety of specializations, but focusing on the most in-demand branches that help you as a future physician define your specialty, the list is as follows.

Bear in mind that depending on your country, some of the branches of medicine might get a difference in names. In this sense, we make a reference to the main branches offered in most countries.

Basic sciences

In general, the basic sciences are related to the study and training to be received by each student as part of their medical career.

Some of these are:

  • Anatomy : it is the branch of medicine and biology that deals with the shape and structure of the body and the relationship of its organs. Also related to the morphology of animals and plants.
  • Biochemistry : it is the branch of chemistry that studies chemical behavior in living systems. It also applies to dentistry, veterinary medicine, and pharmacology in which a biochemist could investigate a drug action.
  • Biostatistics : Also known as biometrics, it is the use of statistical tests to analyze biological data and the interpretation of its results.
  • Cytology or cell biology : it is the branch of scientific life that deals with the structure, composition, function of cells and also the interaction between them in an environment in which they exist.
  • Embryology : it is the branch of biology that studies the formation and early development of living organisms, from the fertilization stage of the ovum to the fetus.
  • Endocrinology: is the branch of medicine and biology related to the specific secretions called hormones and their effect of the endocrine organs that include thyroid, adrenal, pituitary, ovaries, pancreas and testes.
  • Epidemiology: is the study of the appearance, distribution and control of diseases in populations within public health, caused by a virus, bacteria or other factor.
  • Genetics: it is part of biology and refers to the study of genes, inheritance and their effects on the inheritance of specific traits and on other biological processes.
  • Histology : is the branch of medicine and biology that studies the microscopic structure of cells and tissues under an optical microscope.
  • Immunology : it is considered as the main branch of medical science that deals with all the physiological mechanisms of the integral biological defense of all organisms, called the immune system.
  • Microbiology : it is the science that studies microscopic organisms, specifically for them that are under the power of the human eye.
  • Molecular biology : it is the branch of biology and chemistry and deals with the molecular study of the process developed in organisms.
  • Neuroscience: is the scientific study of the nervous system. It is actually part of the fields of chemistry, engineering, mathematics, philosophy, and psychology.
  • Nutrition: is the study of dietary requirements for people. Knowing the composition of foods will help prevent health problems.
  • Pathology:  is the study of disease, its causes, mechanisms and effects on organisms.
  • Pharmacology: is the study of drugs and their origin, nature, properties and effects on living organisms. It is related to the biological effects caused by drugs in organisms.
  • Physiology : it is the branch of medicine and is closely related to anatomy, physiology deals with the activities and processes of living organisms, as well as mechanical and physical functions.
  • Toxicology : it is closely related to medicine, chemistry and biology, basically it is the study of the nature, the effects and the detection of poisons and the treatment of poisoning.

Medical specialties

Once students have completed medical school it is common for them to wish to further their studies by pursuing a specialty of medicine within surgical medicine, internal medicine, diagnostic or clinical specialties.

Diagnostic specialties

These specialties are generally carried out within a clinical laboratory, where the investigation and detection procedures are also performed taking a transfusion of counts and cell therapy.

  • Microbiology: clinical is related to the in vitro diagnosis of diseases caused by bacteria, viruses, fungi and parasites.
  • Immunology: clinical is a broad branch of biomedical science that encompasses the study of all aspects of the immune system in all organisms.
  • Endocrinology: as a subspecialty of internal medicine, it refers to the diagnosis and treatment of endocrine organs.
  • Gastroenterology: is part of internal medicine and includes the study of the gastrointestinal tract through which the digestive system, diseases and treatments.

Clinical specialties

As part of the medical specialties, we can mention the main specialties considered throughout the world.

These are the following:

  • Anesthesiology (AE) or Anesthesia (BE), an anesthesiologist : who administers anesthesia and monitors patients under anesthesia during surgery and other medical procedures.
