The greater tubercle is situated on the lateral side of the humeral head. This tubercle acts as the attachment for the tendons of the supraspinatus, infraspinatus, and teres minor muscles. The greater tubercle is positioned laterally.
Three large smooth sides represent its superior surface and posterior surface for muscle tendon attachment:
- The superior facet of greater tubercle of humerus is for attachment of the supraspinatus muscle
- The middle facet of greater tubercle of humerus is for attachment of infraspinatus
- The inferior facet of greater tubercle of humerus is for attachment of teres minor
Mnemonic: SIT (supraspinatus, infraspinatus, teres minor)
