|
Joints of the Pectoral Girdle: that we have to know
|
Acromioclavicular Joint (Acromioclavicular Lig)
CocacoAcromial Joint (Cocacoacromial Lig) Posterior Sternoclavicular Joint (posterior sternoclavicular Lig) Sternoclavicular Joint (anterior sternoclavicular Lig) Costoclavicular Joint (Costcoclavicular LIgament-Saddle Joint) |
|
|
Ligaments of Scapula
|
Superior Transverse Scapular Ligament- Turns the suprascapular notch into a foramen-above it is an Artery and below it is a Nerve
Coracoclavicular (CCL, 2) - trapezoid and conoid Coracoacromial (CAL) Superior Glenohumeral (SGHL) Middle Glenohumeral (MGHL) Inferior Glenohumeral (IGHL) |
|
|
Rotator Cuff Muscles
|
Subscapularis
Supraspinatus Infraspinatus Teres Minor All innervated by brachial plexus |
|
|
Deltoid Muscle
|
PA: lateral 1/3 of clavicle, acromion, and spine of scapula
DA: Deltoid Tuberosity of Humerus Action: Flex, medially rotate, abduct, extend, laterally rotate humerus BS: Posterior Circumflex Humeral Artery on the posterior aspect and Deltoid Branch of Thoracoacromial arterial trunk Innervation: axillary nerve C5 and C6 (C5 C6 Deltoid it IS!) |
|
|
Teres Major Muscle
|
PA: posterior surface of inferior angle of scapula
DA: medial lip of intertubercular groove of humerus Action: Adducts and medially rotates humerus BS: Circumflex Scapular Artery Innervation: Lower Subscapular Nerve C5 and C6 |
|
|
Serratus Anterior Muscle
|
PA: external surfaces of lateral parts of ribs 1-9
DA: anterior surface of medial border of scapula Action: protracts the scapula and holds it against thoracic wall; rotates scapula/glenoid superiorly BS: lateral thoracic artery Innervation: long thoracic nerve C5, C6, C7 (raise your arms to heaven) |
|
|
Supraspinatus Muscle
|
PA: supraspinous fossa of scapula
DA: superior facet of greater tubercle of humerus Actions: works with deltoid in abduction of humerus, acts with other rotator cuff muscles in stabilizing shoulder joint BS: Suprascapular Artery Innervation: suprascapular nerve C4, C5, C6 |
|
|
Subscapularis Muscle
|
PA: Subscapular fossa (anterior surface of scapula)
DA: lesser tubercle of humerus Largest and Strongest of RCMuscle Action: medially rotates and adducts humerus, helps hold humeral head in place. BS: Subscapular Artery Innervation: Upper and Lower Subscapular Nerves C5, C6, C7 |
|
|
Infraspinatus
|
PA: Infraspinous fossa of scapula
DA: middle facet of greater tubercle of humerus Action: Laterally rotates humerus, helps hold the humeral head in place BS: Suprascapular Artery Innervation: Suprascapular Nerve C5 and C6 |
|
|
Teres Minor Muscle
|
PA: middle part of lateral border of scapula
DA: inferior facet of greater tubercle of humerus Action: Laterally rotates humerus and helps hold humeral head in place BS: circumflex scapular artery Innervation: Axillary Nerve C5 and C6 |
|
|

|
|
Triangular Space
|
Borders: Long head of triceps Laterally, Teres major inferiorly, teres minor superiorly
Contents: Circumflex Scapular Artery (deep) |
|
|
Triangular Interval
|
Borders: Teres Major superiorly, lateral head of triceps laterally, long head of triceps medially
Contents: Deep Brachial Artery and Radial Nerve which both will travel to the posterior aspect of the arm |
