The infraglenoid tubercle is the part of the scapula from which the long head of the triceps brachii muscle originates. The infraglenoid tubercle is a tubercle located on the lateral part of the scapula, inferior to (below) the glenoid cavity. The name infraglenoid tubercle refers to its location below the glenoid cavity.
Function
The infraglenoid tubercle is the origin of the long head of the triceps brachii muscle.{{Cite journal|date=2019-03-01|title=An anatomic study on the origin of the long head of the triceps brachii|journal=JSES Open Access|language=en|volume=3|issue=1|pages=5–11|doi=10.1016/j.jses.2019.01.001|issn=2468-6026|doi-access=free|last1=Nasu|first1=Hisayo|last2=Baramee|first2=Phichaya|last3=Kampan|first3=Natnicha|last4=Nimura|first4=Akimoto|last5=Akita|first5=Keiichi|pmid=30976729|pmc=6443837}}{{Cite journal|last1=Handling|first1=Matthew A.|last2=Curtis|first2=Alan S.|last3=Miller|first3=Suzanne L.|date=2010-01-01|title=The origin of the long head of the triceps: A cadaveric study|url=http://www.sciencedirect.com/science/article/pii/S1058274609002869|journal=Journal of Shoulder and Elbow Surgery|language=en|volume=19|issue=1|pages=69–72|doi=10.1016/j.jse.2009.06.008|pmid=19748801|issn=1058-2746}} It helps to stabilise the muscle origin.
