The American Heritage® Medical Dictionary is a comprehensive medical reference for students, health care professionals, and anyone who wants to understand medical vocabulary. New treatments, tests, and insights into health have greatly expanded medical terminology, and this dictionary reflects recent developments in medicine and health care.
It contains more than 45,000 clear, concise definitions covering diseases and conditions, treatments, and microorganisms, plus several hundred entries on widely used prescription and non-prescription drugs. Informative illustrations and tables support the text.
Definitions are plain and direct, giving enough technical depth without drifting into academic jargon. That makes the dictionary detailed enough for professionals while remaining accessible to general readers. Biographical entries are also included. Enfour’s app makes the content quick to search on iPhone, iPad, and Mac.
