Document Summary

Appendicular skeleton and joints: pectoral girdle, clavicle, scapula, upper limb, pelvic girdle, os coxae, lower limb. Important for lots of different professions: kin, orthopaedics, physiotherapy, athletic training, nursing etc, great opportunity to problem solve, but lots of memorization. Upper limb vs lower limb: upper and lower limb have similar overall arrangement, but adapted to serve unique functions. In quadrupeds (animals) all 4 limbs served purpose of stabilization and locomotion. In bipeds, evolved so that lighter upper limb does complex fine movement (grasping, reaching) while heavier lower limb does powerful movements and supports weight during walking and running etc. Overview of upper limb: divided into 4 regions, shoulder, arm, forearm, hand, divided by 3 main joints, glenohumeral (gh/shoulder, elbow, wrist. Bones: pectoral girdle (clavicle and scapula, humerus, radius, ulna, bones of the hand and wrist. Pectoral: made up of clavicle and scapula, attaches upper limbs to axial skeleton via sternoclavicular joint, highly mobile, weak and injury prone though.
