41
Supraspinatous origin
from medial twothirdof supra spinous fossa & fascia
42
supraspinatus insertion
under acromion into tendonabove shoulder joint f at highest facet ofgreater tubercleof humerus tendon blend into articular capsule
43
supraspinatus nerve & action
supra scapular nerve The conventional view is that supraspinatus initiates abduction of the shoulder (from 0 to 18 degrees) and assists deltoid in abduction thereafter. However, there is evidence that both supraspinatus and deltoid are involved throughout the range of abduction, including initiation of the movement. • As part of the rotator cuff, supraspinatus helps to stabilize the head of the humerus in the glenoid fossa during movements of the glenohumeral joint.
44
The tendon of supraspinatus is separated from the coracoacromial ligament, acronion & deltoid
by subacromial bursa if inflamed abduction of shoulderpainful
45
infraspinatus origin
Origin: from the medial twothirds of the infraspinous fossa, and from the deep surface of the infraspinous fascia.
46
infraspinatus insertion
Its fibres converge to a tendon which glides under the lateral border of the spine of the scapula, and then passes across the posterior aspect of the capsule of the shoulder joint to be attached to the middle facet on the greater tubercle of the humerus.  The tendon is sometimes separated from the capsule by a bursa, which may communicate with the joint cavity.
47
infraspinatus nerve & action
Innervation: by the suprascapular nerve, C5 and 6.  Action: Infraspinatus is a lateral rotator of the humerus. Together with supraspinatus, subscapularis and teres minor, it helps to stabilize the head of the humerus in the glenoid fossa during shoulder movements.
48
sub scapularis origin
Origin: from the medial two-thirds of the subscapular fossa. Other fibres arise from tendinous intramuscular septa, which are attached to ridges on the bone, and from the aponeurosis which covers the muscle.
49
Subscapularis insertion
Insertion: The fibres converge laterally into a broad tendon which is attached to the lesser tubercle of the humerus and the front of the articular capsule.  The tendon is separated from the neck of the scapula by the large subscapular bursa, which communicates with the shoulder joint.
50
. innervation & action of subscapularis
Innervation: by the upper and lower subscapular nerves, C5, 6.  Action: Subscapularis is a medial rotator of the humerus. Together with supraspinatus, infraspinatus and teres minor, it helps to stabilize the head of the humerus in the glenoid fossa during shoulder movements.
51
Teresmajor origin. insertion
 Origin: from the oval area on the dorsal surface of the inferior scapular angle.  Insertion: to the medial lip of the intertubercular sulcus (bicipital groove) of the humerus.
52
nerve &actionTeres major
Innervation: by the lower subscapular nerve, C5, 6 and 7. • Action: Teres major draws the humerus backwards and rotates it medially. (Moore: Adducts and medially rotates arm).  Teres major can be palpated posterior to the posterior axillary fold during adduction of the humerus against resistance.
53
Teres minor Origin & insertion
Origin: from the upper twothirds of a flattened strip on the dorsal surface of the scapula adjoining its lateral border.  Insertion: It runs upwards and laterally. The upper fibres end in a tendon attached to the lowest facet on the greater tubercle of the humerus. The lower fibres are attached directly into the humerus distal to this facet and above the origin of the lateral head of triceps.  The tendon passes across, and blends with, the lower posterior surface of the capsule of the shoulder joint.
54
nerve & action of Teres minor .
Innervation: by the axillary nerve, C5 and 6.  Action: Teres minor acts as a lateral rotator and weak adductor of the humerus. Together with supraspinatus, infraspinatus and subscapularis, it helps stabilize the head of the humerus in the glenoid fossa during shoulder movements.
55
action of rotator cuff
during movementof the glenohumeral (shoulder) joint is to hold the humeral head in the glenoid cavity of the scapula
56
quadrangular space boundaries
Above: by subscapularis, the capsule of the shoulder joint and teres minor. • Below: teres major. • Medially: the long head of triceps. • Laterally: the surgical neck of the humerus. • The axillary nerve and the posterior circumflex artery and vein pass through this space.
57
The upper triangular space is bounded:
Above by subscapularis anteriorly, teres minor posteriorly, • Below: teres major. • Laterally: the long head of triceps.  The circumflex scapular artery passes through this space.
58
 The lower triangular space is bounded:
Above by the teres major. • Medially: the long head of triceps. • Laterally: the humerus.  The radial nerve and the profunda brachii vessels pass through this space.
