Cards in this deck (23)
- 1Shoulder Girdle consists of:Clavicle
Scapula - 2Classify the ClavicleLong bone
Crank-like shape - 3Classify the ScapulaIrregular bone
Triangular is shape
Articulates with arm and clavicle - 4Feature of Scapula - Costal Surface- Concave - Anterior
- Forms large subscapular fossa (depression)
- For 'fleshy' muscle attachment - 5Feature of Scapula - Dorsal Surface- Convex - Posterior
- Spine (projection) divides sides unevenly superiorly and inferiorly
- Provides attachment for 'fleshy' muscles - 6Feature of Scapula - Superior, Medial and Lateral BordersSuperior: Posterior, right side of crest; left of suprascapular notch
Medial: Posterior, medial side
Lateral: Posterior, lateral side; concaves in - 7Features of Scapula - Superior, Inferior and Lateral AnglesSuperior: Posterior view; left of superior border
Inferior: Bottom point of scapula
Lateral: Forms the glenoid fossa - articulates with head of humerus to form shoulder jnt - 8Features of Scapula - Spine and Root of SpineSpine: Posterior, Superior to Inferior angle - divides dorsal surface
Root: Medial; Bottom of Spine - 9Features of Scapula - Acromion Process- Expanded continuation of Spine
- Articulates with Clavicle - 10Features of Scapula - Coracoid Process- Anterior - behind acromion from posterior view
- Concave down
- Provides muscle and ligament attachment - 11Features of Scapula - Glenoid Fossa- Shallow basin-like depression
- Lateral - articulates with humerus
- Faces Superiorly and Anteriorly - 12Features of Scapula - Subscapular, Supraspinous, Infraspinous FossaSubscapular: Costal surface, Anterior; Concave
Supraspinous: Posterior, Superior to Spine
Infraspinous: Posterior, Inferior to Spine - 13Features of Scapula - Suprascapular NotchLateral to Superior Border
- 14Features of Scapula - Supraglenoid and Infraglenoid TubercleSupraglenoid: Superior to glenoid fossa
Infraglenoid: Inferior to glenoid fossa
- Both provide for muscle attachment - 15Orientate a Disarticulated ScapulaLateral: Glenoid Fossa
Posterior: Spine - 16Features of Clavicle - Acromial End- Lateral, flat surface
- Articulates with Acromion Process of Scapula - 17Features of Clavicle - Sternal End- Medial; rounded
- Articulates with Sternum - 18Features of Clavicle - Superior SurfaceSmooth
- 19Features of Clavicle - Inferior SurfaceRough
- Attachment of muscle and ligament - 20Features of Clavicle - Roughened Area of Costoclavicular ligamentMedial End; Inferior
- 21Trapezoid LineLateral; Inferior
- 22Conoid TubercleInferior; Concave up, Medial to Trapezoid Line
- 23CurvaturesSuperior view: Convex Forward - Medial 2/3
