Gross Anatomy of the Shoulder Joint
| Question | Answer |
|---|---|
| Components of Shoulder Girdle | Scapula, Clavicle, and Manubrium |
| Angles and Borders of Scapula | Superior Angle (@ T2) and Inferior Angle (@ T7) and Vertebral/Axillary Borders |
| Processes and Notches of Scapula | Acromion/Coracoid Process and Suprascapular/Spinoglenoid Notches |
| Scapular Fossa | Glenoid Fossa, Supraspinous Fossa, Infraspinous Fossa, and Subscapular Fossa |
| Scapular Tubercles | Supraglenoid and Infraglenoid Tubercles |
| Clavicle Landmarks | Proximal/Sternal End (Rounded), Acromial End (Flatter), Trapezoid Line, Conoid Tubercle, Subclavius Groove |
| 5 Muscles that Attach to Clavicle | Subclavius, Sternocleidomastoid, Trapezius, Deltoid, and Pec Major |
| 3 Sections of Sternum | Manubrium, Body, and Xiphoid Process |
| Sternal Landmarks | Sternal Angle, Jugular Notch, Rib Facets (1-7), Articular Surfaces for Clavicles |
| Anterior Deltoid Prox. | Clavicle |
| Middle Deltoid Prox. | Acromion, Clavicle, Scapular Spine |
| Posterior Deltoid Prox. | Scapular Spine |
| Deltoid Dist. | Deltoid Tuberosity |
| Deltoid Anterior Act. | Glenohumeral Flexion |
| Deltoid Middle Act. | Glenohumeral ABduction (supraspinatus initiates) |
| Deltoid Posterior Act. | Glenohumeral Extension |
| Deltoid Inn. | Axillary Nerve |
| 4 Scapular Muscles (Rotator Cuff) | Supraspinatus, Infraspinatus, Teres Minor, Subscapularis |
| Supraspinatus Prox. | Supraaspinous Foss |
| Supraspinatus Dist. | Greater Tubercle of Humerus |
| Supraspinatus Act. | ABduction of Humerus |
| Supraspinatus Inn. | Suprascapular Nerve |
| Coracoacromial Arch Components | Acromion, Coracoid Process, Coracoacromial Ligament, Supraspinatus Runs Through Arch |
| Infraspinatus Prox. | Infraspinous Fossa |
| Infraspinatus Prox. | Greater Tubercle of Humerus |
| Infraspinatus Act. | External Rotation |
| Infraspinatus Inn. | Suprascapular Nerve |
| Subscapularis Prox. | Subscapular Fossa |
| Subscapularis Dist. | Lesser tubercle of humerus |
| Subscapularis Act. | Internal Rotation |
| Subscapularis Inn. | Upper/Lower Subscapular Nerves |
| Teres Minor Prox. | Superior lateral scapular border |
| Teres Minor Dist. | Greater tubercle of humerus |
| Teres Minor Act. | External Rotation |
| Teres Minor Inn. | Axillary Nerve |
| Teres Major Prox. | Dorsal inferior scapular angle |
| Teres Major Dist. | Medial intertubercular groove |
| Teres Major Act. | ADduction and IR of Humerus |
| Teres Major Inn. | Lower Scapular Nerve |
| Borders of Quadrilateral Space | Teres Minor/Major, Triceps Long Head, Humerus |
| Contents of Quadrilateral Space | Posterior Humeral Circumflex Artery and Axillary Nerve |
| Borders of Triangular Space | Teres Minor/Major and Medial Long Head of Triceps |
| Contents of Triangular Space | Circumflex Scapular Artery and Vein |
| Borders of Internal Triangle | Teres Major, Long and Lateral Head of Triceps, and Humerus |
| Contents of Internal Triangle | Radial Nerve and Deep Profunda Artery/Vein |
| Suprascapular Nerve | Runs along suprascapular ligament and innervates Infraspinatus |
| Axillary Nerve | Innervates Deltoid and Teres Minor |
| 3 Branches of Subclavian Artery | Transverse Cervical, Dorsal Scapular, and Suprascapular |
| 3 Branches of Axillary Artery | Posterior Humeral Circumflex, Anterior Humeral Circumflex, and Subscapular |
| Typically the __ branches off more proximal to the heart than the __. (Ant/Post Humeral Circumflex Arteries) | Posterior more proximal than Anterior |
| Veins of Shoulder Region | Subclavian, Axillary, Basilic, Cephalic |
