The scope and sciences underpinning human medicine overlap many other fields. Dentistry and psychology, while separate disciplines from medicine, are considered medical fields.
Midlevel Practitioners
Nurse practitioners, midwives and physician assistants, treat patients and prescribe medication in many legal jurisdictions.
Veterinary Medicine
Veterinarians apply similar techniques as physicians to the care of animals. The original focus of veterinary medicine was primarily the health care of domestic animals. In recent years the discipline has broadened to include all vertebrate animals and even some of the more economically valuable or scientifically interesting invertebrates. Veterinary and human medicine had similar origins but diverged in the West largely under the influence of Christian doctrine which emphasized a fundamental difference between humans and all other species. The two disciplines re-converged to some degree after the Renaissance when scientific study of anatomy and physiology revealed undeniable similarities between humans and other animals. The similarities further extend into pathology and disease control leading the early pioneer in scientific pathology Rudolph Virchow to proclaim the doctrine of "one medicine."
Physicians have many specializations and subspecializations which are listed below. There are variations from country to country regarding which specialties certain subspecialities are in.
