Appendicular Skeleton Flashcards
Two parts of pectoral girdle
Scapula and Clavicle
Three portions of clavicle
Body
Medial/Sternal end
Lateral/Acromial end
Appendicular skeleton articulates with axial skeleton at this point only
Manubrium
Function of clavicle
Braces scapula to hold shoulder in place
Attachment place for muscles
If collarbone isn’t broken- this commonly occurs
Acromioclavicular joint sprain
3 borders of scapula
Vertebral/medial border (side)
Superior border (top)
Axillary/lateral border (top right)
3 angles of scapula
Superior angle (top right) Inferior angle (bottom point) Lateral angle (holds acromion process, bears glenoid cavity)
3 fossas of scapula
Subscapular fossa Supraspinous fossa (above spine) Infraspinous fossa (below spine)
Labrum
Increases the depth of the glenoid cavity
Increases stability of shoulder
Humerus parts
Head, neck, greater/lesser tubercles, bicipital groove, and shaft
Audograph
Tissue from own body
Allowgraph
Tissues from another persons body
Bursa
Limit friction (sock) between bones or ligaments
Capitulum
Articulates with the head of the radius
Trochlea
Articulates with the ulna
Trochlear notch
“Ice Cream scooper”
Bony point at elbow
Olecranon
Does the ulna or radius articulate with carpal bones?
Radius
