Anatomical terms of muscle [edit on Wikidata]

The template is invoked using double-brace syntax (with the result similar to that shown at the right), coded as follows:

{{Infobox Muscle
| Name=Quadriceps femoris muscle
| Latin= musculus quadriceps
                         femoris
| GraySubject = 128
| GrayPage    = 470
| Image = Illu lower extremity
                    muscles.jpg
| Width   = 250
| Caption = Muscles of lower
            extremity
| Origin  = combined rectus
   femoris and [[vastus]] muscles
| Insertion =
| Blood     = [[femoral artery]]
| Nerve     = [[Femoral nerve]]

The template parameters are (Camel case requiring upper/lowercase):

• Name = English name for structure.
• Latin = Latin name for structure.
• GraySubject = Gray's Anatomy subject number, such as: 189.
• GrayPage = Gray's Anatomy page number, such as: 825.
• Image    = top image (omit "Image:").
• Width    = width of top image (in pixels, default=250).
• Caption  = caption under top image.
• Image2    = 2nd top image (omit "Image:").
• Width2    = width of 2nd image (in pixels, default=250).
• Caption2  = caption under 2nd top image.
• Map         = map procedure after 2nd image.
• MapCaption = caption under map image.
• Origin = any origin text
• Insertion = any insertion text
• Blood = related arteries
• Nerve = related nerves
• Action = use, such as "Knee extension"
• Antagonist = opposing muscle
• MeshName    = MeSH name
• MeshNumber = MeSH number code
• DorlandsPre   = Dorlands prefix, such as: i_09.
• DorlandsSuf   = Dorlands suffix, such as: 12454066.

• BoxWidth    = width of infobox (in em/pixels, default 20em), also "boxwidth"
• ColumnGap =     - extra spaces between infobox columns.

Most parameters begin with a capital letter.

The template was implemented in January 2006 using the MediaWiki parser-functions language (which was updated in January 2008 to run with a recursive descent parser).

Changes should be made and verified in a test-version of the template by copying it into user-space (under "User:XXX/Template:Infobox_Muscle"). Changes can be checked by editing actual articles by edit-preview (not Save) with the template-brace calls prefixed by "{<font/>{User:XXX/Template:...}}" but never saved that way.

When modifying the template or documentation ("/doc" subpage), it is often necessary to purge the template cache (using "action=purge"), such as to display modified documentation:

http://en.wikipedia.org/w/index.php?title=Template:Infobox_Muscle&action=purge

Running old versions of the template can be very confusing and frustrating when trying to install and verify improvements copied from test-versions of the template (so remember "action=purge").

• Template:Infobox_Brain - for parts of the brain.
• Template:Infobox_Bone - for bones of the body.
• Template:Eye - articles on parts of the eye.
