UE, Superficial Back And Intercostals Flashcards
FITB
_______________ __________ is the only anatomical joint between UE and axial skeleton
Sternoclavicular joint
The clavicle or “collar bone” does what? And is made up of what portions?
Allows for passage of neurovascular bundle to/from upper extremity
Sternal End: enlarged, triangular
Acromial end: flatter, tapered, articulates with acromion of scapula at acrominoclavular (AC) joint
Considered tubercle: inferior distal surface near acromial end
Trapezoid line: extending laterally from concord tubercle toward acromial articular surface
*Palpate from clavicular head near sternal notch to acromion - distal clavicle should terminate superior to acromion
Name the borders of the scapula and angles at which the borders meet
Borders: medial (vertebral), lateral (axillary), superior
Angles: at which they meet
- Inferior: union of lateral and medial borders
- Lateral (bearing the glenoid fossa): union of lateral and superior orders
- Superior: union of medial and superior borders
Palpate along borders and angles of scapluae
Describe and name parts of the scapula.
Subscapular fossa: slightly concave anterior surface
Spine: a ridge of bone on the dorsal surface
Acromion Process: Lateral, freely projecting process of the spine, articulated with distal clavicle forming acromioclavicular (AC) joint
Infraspinous Fossa: Dorsal surface inferior to the spine
Supraspinous Fossa: Dorsal surface superior to the spine
Coracoid Process: thick, curved process attached to the superior border projecting anterolaterally
Scapular Notch: Superior border medial to the coracoid process
Glenoid Fossa/Cavity: slightly concave surface of the lateral angle; articulates with the head of the humerus
Supraglenoid Tubercle: immediately superior to the glenoid fossa
Infraglenoid Tubercle: immediately inferior to the glenoid fossa
