Document Summary
The anatomy of joints: joint classi cation, by range of motion, synovial joints, characteristics of synovial joint, don"t need to know types, naming joints, speci c to the bones that are articulating. Compare trunk to shoulder: function and range of motion determined by anatomical design (including substance that joins) Fibrous joints: allow no movement (higher force absorption) o sutures of the skull (lines) Cartilaginous joints: allow limited movements (force absorption, intervertebral discs, between right and left pubis bones (pubis symphysis) Synovial joints: allow large range of movements o hip joint. Synovial fluid: lubricates the joint, injury/stress results in swelling ! Capsule (connective tissue: may or may not have thickening called intrinsic ligaments ! Extrinsic ligaments: support the joint & connect the articulating bones. Sternum & clavicle = sternoclavicuar: types of movement in pectoral girdle ! Elevation/ depression: scapula & clavicle = acromioclavicular !
