Week Two OIA Upper E Flashcards
Origin of supraspinatus
Supraspinous fossa of scapula
Insertion of supraspinatus
greater tubercle of the humerus
Supra = greater rubercle
Action of supraspinatus
Shoulder abduction and stabilization
Abduction to stabilization
Origin of infraspinatus
infraspinatus fossa of scapula
Insertion of infraspinatus
greater tubercle of the humerus
Action of infraspinatus
shoulder laterally rotation, adduction, stabilization
Adds lateral rotation
Origin of Teres Minor
Upper 2/3 of the lateral edge of the scapula
2/3 of the lateral edge of the scap
Insertion of Teres Minor
Head of the humerus, greater tubercle of the humerus
Greater head
Action of Teres Minor
shoulder laterally rotation, adduction, and stabilization
Adds lateral rotation
Origin of subscapularis
Subscapular fossa of scapula
Insertion of subscapularis
lesser tubercle of humerus
Sub is lesser
Action of subscapularis
Shoulder medial rotation and stabilization
mediocer
Origin of Rhomboids Major
The spinous process of T2-T5
2-5 spines
Insertion of rhomboids major
lower portion of the medial border of the scapula
Major: lower and medial to the scap
Action of rhomboids major
scapula: adduction, elevation, downward rotation
Add elevation to go down rotations
