Exam 1111
Proximal Humerus and Shoulder Girdle
Question | Answer |
---|---|
Proximal Humerus | Head, greater and lesser tuburcle, intertubecular groove, anatomican and surgical neck, body |
Head | Most proximal part |
Anatomical Neck | slightly constricted area directly below and lateral to head |
Lesser Tubercle | Directly below anatomic neck on anterior surface |
Greater Tubercle | Larger process located laterally |
Intertubecular Groove | deep groove between thw tubercles |
Body | distal to surgical neck |
clavicle and scapula | connect each upper limb to the trunk or axial skeleton |
scapula | upper margin is at the level or 2nd posterior rib; lower margin is at level of 7th posterior rib |
clavicle | Acromion of scapula, acromioclavicular joint, acromial extremity, body, sternal extremity, sternoclavicular joint |
sternoclavicular joint | articulates medial (sternal) end of clavicle and manubrium of sternum |
Acromioclavicular joint | articulates lateral (acromial) end of clavicle with acromion os scapula |
Shoulder Joint | articulates head of humerus and glenoid cavity |
Scapula | corocoid process, scapular notch, superior angle, body, inferior angle, coastal surface, neck, lateral angle, glenoid cavity, acromion |
Scapular Spine | begins at vetebral border and continues laterally, ending at acromion |
Acromion | expanded lateral end of scapular spine, extending superiorly and posteriorly to the glenoid cavity |
Corocoid process | thick, beaklike process projecting anteriorly beneath clavicle |
Scapular Borders | Vetebral(Medial), Axillary (lateral), Superior |
Scapular Surfaces | Coastal (anterior), Dorsal (posterior) |
Scapular Angles | Superior, Inferior, Lateral |
Scapula (posterior view) | Crest of spine, acromion, supraspinous fossa, infraspinous fossa, dorsal surface |
Scapulohumeral joint | spheroidal |
sternoclavicular joint | plane |
acromioclavicular joint | plane |
AP projection Shoulder External Rotation | Epicondyles parallel, greater tubercle seen in full profile laterally, scapulohumeral joint centered, proximal humerus, upper scapula, and clavicle well visualized |
AP Shoulder Internal Rotation | epicondyles perpendicular, lesser tubecle profilled medially, scapulohumeral joint centered (1in below corocoid), proximial humerus, scapula, and clavicle well visualized |
