Template documentation[view] [edit] [history] [purge]
This template does not display in the mobile view of Wikipedia; it is desktop only. See Template:Navbox visibility for a brief explanation.

This is a navigational template created using {{navbox}}. It can be transcluded on pages by placing {{Heart anatomy}} below the standard article appendices.

Initial visibility

This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.

To change this template's initial visibility, the |state= parameter may be used:

  • {{Heart anatomy|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.
  • {{Heart anatomy|state=expanded}} will show the template expanded, i.e. fully visible.

Templates using the classes class=navbox ({{navbox}}) or class=nomobile ({{sidebar}}) are not displayed in article space on the mobile web site of English Wikipedia. Mobile page views accounted for 60% to 70% of all page views from 2020 through 2025. Briefly, these templates are not included in articles because 1) they are not well designed for mobile, and 2) they significantly increase page sizes—bad for mobile downloads—in a way that is not useful for the mobile use case. You can review/watch phab:T124168 for further discussion.

Editing this template

This template is a navigation box relating to anatomy that provides links to related topics.

When editing the links in this template:

  • Include a single link to the article.
  • Do not add: synonyms or information about the structure itself (eg nerve or muscle supply). These should be found within an article.

Help can be found at: Template talk:Medicine navs or by posting at the talk page for WikiProject Anatomy.

A full list can be found in the {{list of anatomy templates}}.

The above documentation is transcluded from Template:Navbox documentation. (edit | history)
Editors can experiment in this template's sandbox (create | mirror) and testcases (create) pages.
