Document Summary

Appendicular skeleton: pectoral girdle clavicle and scapula, upper limbs, pelvic girdle lower limbs to axial skeleton (os coxae, lower limbs. Important for lots of different professions: great opportunity to problem solve. Upper limbs vs. lower limbs: upper and lower limbs have similar overall arrangement, but adapted to serve unique functions. In quadrupeds, all 4 limbs served purpose of stabilization and locomotion. Overview of upper limbs: divided into 4 regions, shoulder, arm upper, forearm lower arm, hand, divided by 3 main joints, glenohumeral shoulder joint, elbow, wrist. Bones of the upper limbs: pectoral girdle (clavicle & scapula) clavicle and scapula, humerus in arm, radius and ulna forearm, bones of the hand & wrist. Scapula: floating no boney attachment, superior border, medial border, lateral bored, superior angle, lateral angle glenoid cavity. Inferior angle: where the humerus articulates with, spine of the scapula, land mark to determine posterior, supraspinous fossa. Infra and supra glenoid tubercle biceps and triceps attachment.
