GradeBuddy is best !used as a supplement to your own notes, not as a substitute. !VII. Palmer Aponerousis VIII. Fascia IX. Palmar Arches Current Lecture A. Upper Extremity1. Shoulder: dynamic base of support2. Elbow: allow hand to approach or extend away from the body3. Forearm: adjust approach of the hand to object4. Wrist: broadens placement of hand increases mobilityB. Wrist Joint1. Loss of function at wrist cane replaced by movement at other joints2. Control length-tension of the multi-articular muscles allowing us to permit fine adjustment-power grip3. Radiocarpala. Radius and proximal carpalsb. Condyloid joint- flexion-extension- abduction-adduction4. Distal Radioulnara. Privot jointC. Stability1. Bone structure: good2. Ligaments and capsule: excellent3. Muscle support: goodD.
