Document Summary

* all of anatomy is a mirror image unless otherwise stated: pectoral girdle, clavicle, scapula, upper limb, pelvic girdle, os coxae, lower limb. Why limbs: why do we care about limbs, important for lots of different professions, kin, orthopedics, physio, athletic training, nursing, etc, great opportunity to problem solve, but lots of memorization. Upper limbs vs. lower limb: upper and lower limb have similar overall arrangement, but adapted to serve unique functions. In quadrupeds, 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 & running, etc. Upper limb: divided into 4 regions, shoulder, arm, forearm, hand, divided by 3 main joints, glenohumeral (gh, elbow, wrist, bones, pectoral girdle (clavicle and scapula, humerus, radius, ulna, bones of the hand/wrist.
