Joints of the pelvic girdle and lower extremities
Synovial Joint pg 215
SYNOVIAL JOINT PERIOSTEUM LIGAMENT JT CAVITY FIBROUS CAPSULE SYNOVIAL MEMBRANE ARTICULAR CARTILAGE
Knee Joint Much more complex than elbow Much less stable than other hinge joints Some gliding and rotation structurally 3 separate joints No single joint capsule
Joint Shapes Saddle: articular surface both concave + convex pg 225 Joint Shapes Saddle: articular surface both concave + convex side-to-side, back-forth movement (eg) carpometacarpal jt of thumb Ball + Socket: spherical head + round socket multiaxial movement (eg) shoulder, femur
Bursae & Tendon Sheaths Bursae: flat, fibrous sac w/synovial membrane lining Tendon Sheaths: elongated bursae that wraps around tendons 3 Factors in Joint Stability: Muscle Tone Ligaments Fit of Articular Surface pg 219
pg 224 Joint Shapes Hinge: cylindrical end of 1 bone fits into trough shape of other angular movement-1 plane (eg) elbow, ankle, interphalangal Plane: articular surface in flat plane Short gliding movement (eg) intertarsal, articular processes of vertebrae
Joint Shapes Condyloid: egg-shape articular surface + oval concavity pg 225 Joint Shapes Condyloid: egg-shape articular surface + oval concavity side-to-side, back+forth movement (eg) metacarpophalangeal (knuckle) Pivot: round end fits into ring of bone + ligament rotation on long axis (eg) prox. radius/ulna, atlas/dens
