Top-level broad categories
Increasingly specific subcategories
Detailed descriptor relationships

Main Categories in Medical Subject Headings

Medical Subject Headings cover a wide range of medical knowledge. They help in precise and flexible searches across many medical fields.

Category	Description	Example Descriptors
Anatomy	Body structures and systems	Cardiovascular System, Nervous System
Diseases	Medical conditions and disorders	Cancer, Diabetes Mellitus
Chemicals/Drugs	Pharmaceutical and chemical substances	Antibiotics, Enzymes
Techniques	Medical procedures and methodologies	Surgical Procedures, Diagnostic Techniques

“The MeSH Structure provides a universal language for medical information, bridging communication across global research platforms.” – NLM Research Team

Researchers can use descriptors like “Jejunum” and “Enteritis” for detailed searches. This shows how flexible and powerful the Medical Subject Headings system is.

Applications of MESH in Research

Medical Research now uses advanced systems to find information in the huge world of science. MeSH (Medical Subject Headings) is a key tool for finding detailed and accurate research.
