It should not be confused with the [[triangular interval]], which transmits the [[radial nerve]] and the Profunda brachii artery also called as the [[deep artery of the arm]].

==Boundaries==

It has the following boundaries:

* Inferior: the superior border of the [[Teresteres major]] inferiorly;

* Lateral: the long head of the [[Tricepstriceps]] laterally;

* Superior: Teres minor

For the superior border, some sources list the [[Teresteres minor]],<ref name="isbn0-7817-5309-0"/><ref>{{SUNYAnatomyLabs|03|05|01|01}} - "Triangular Space of Scapular Region"</ref> while others list the [[Subscapularissubscapularis]].<ref name="isbn0-443-06612-4">{{cite book |author=Adam Mitchell; |author2=Drake, Richard; |author3=Gray, Henry David; |author4=Wayne Vogl |title=Gray's anatomy for students |publisher=Elsevier/Churchill Livingstone |___location= |year=2005 |pages= |isbn=0-443-06612-4 |oclc= |doi=}}</ref>

Unlike the quadrangular space or the triangular interval, no major nerve passes through the triangular space.
