Rotator Cuff

Question 1

Teres Minor Origin and Insertion

Answer 1

Origin: Lateral border of the scapula
Insertion: Greater tubercle of the humerus

Question 2

Teres Minor Isolated and Integrated Function

Answer 2

Isolated Function: concentrically accelerates shoulder external rotation
Integrated Function: eccentrically decelerates shoulder internal rotation, isometrically stabilizes the shoulder girdle

Question 3

Infraspinatus Origin and Insertion

Answer 3

Origin: infraspinous fossa of the scapula
Insertion: middle facet of the greater tubercle of the humerus

Question 4

Infraspinatus Isolated and Integrated Function

Answer 4

Isolated Function: concentrically accelerates shoulder external rotation
Integrated Function: eccentrically decelerates shoulder internal rotation, isometrically stabilizes the shoulder girdle

Question 5

Subscapularis Origin and Insertion

Answer 5

Origin: subscapular foss of the scapula
Insertion: lesser tubercle of the humerus

Question 6

Subscapularis Isolated and Integrated Function

Answer 6

Isolated Function: concentrically accelerates shoulder internal rotation
Integrated Function: eccentrically decelerates shoulder external rotation, isometrically stabilizes the shoulder girdle

Question 7

Supraspinatus Origin and Insertion

Answer 7

Origin: supraspinous fossa of the scapula
Insertion: superior facet of the greater tubercle of the humerus

Question 8

Supraspinatus Isolated and Integrated Function

Answer 8

Isolated Function:concentrically accelerates abduction of the arm
Integrated Function: eccentrically decelerates the adduction of the arm, isometrically stabilizes the shoulder girdle
