The triangular interval (also known as the lateral triangular space [ [http://iris3.med.tufts.edu/dentgross/labguide/Shoulder4.html Photo at tufts.edu] ] and lower triangular spacecite book |author=Kyung Won, PhD. Chung |title=Gross Anatomy (Board Review) |publisher=Lippincott Williams & Wilkins |location=Hagerstown, MD |year=2005 |pages=34 |isbn=0-7817-5309-0 |oclc= |doi=] ) is a space found in the axilla.

Borders

Two of its borders are as follows:
* teres major - superior
* long head of the triceps brachii - medial

Some sources state the lateral border is the humerus, [cite book |author=Adam Mitchell; Drake, Richard; Gray, Henry David; Wayne Vogl |title=Gray's anatomy for students |publisher=Elsevier/Churchill Livingstone |location= |year=2005 |pages=650 |isbn=0-443-06612-4 |oclc= |doi=] cite web |url=http://anatomy.uams.edu/anatomyhtml/topogr_back.html |title=uams.edu |accessdate=2008-01-02 |format= |work=] while others define it as the lateral head of the triceps,cite web |url=http://www.ucd.ie/vetanat/ga-subject/f-limb/fl1.html |title=ucd.ie |accessdate=2008-01-02 |format= |work=] or the medial head of the triceps.cite book |author=Kyung Won, PhD. Chung |title=Gross Anatomy (Board Review) |publisher=Lippincott Williams & Wilkins |location=Hagerstown, MD |year=2005 |pages=34 |isbn=0-7817-5309-0 |oclc= |doi=] (The effective difference is relatively minor, though.)

Contents
