What is MeSH?
MeSH stands for Medical Subject Headings which can be found in the MedLine database. It is what is called a "controlled vocabulary." This means that each article in that database is assigned specific terms to identify the content of that article. It is helpful to search using these terms so you do not miss out on articles. If you enter a search term that is not a MeSH term and the author of the article is using another term, you can miss out on finding articles that are useful to you.
