Document Summary

Limbs offer an opportunity for problem solving. Lower limbs are more important for generating power. Upper limbs has more ability for more fine motor control. Pectoral girdle anchors upper limb to axial skeleton. Sternoclavicular is the only bony attachment between axial and appendicular skeleton. Sternoclavicular joint attaches the sternum and clavicle. Conoid tubercle ligaments attach to hold clavicle down. Trapezoid line ligaments attach to hold clavicle down. Supraspinous fossa above the spine of the scapula. Spine porttusion that runs along the back splits the back of the scapula into two areas, becomes the acromion. Infraspinous fossa below the spine of the scapula. Subscapular fossa below (when you tilt forward, the anterior surface sits underneath the scapula) Supraglenoid tubercle above muscle attachment of biceps. Glenoid cavity what the humerus articulates with. Infraglenoid tubercle below - muscle attachment of triceps. Glenoid cavity at lateral angle depression that covers the lateral angle. Inter-tubercular sulcus contains a tendon of the biceps.
