1 Joints of the pelvic girdle and lower extremities

2 Synovial Joint pg 215

3 SYNOVIAL JOINT PERIOSTEUM LIGAMENT JT CAVITY FIBROUS CAPSULE
SYNOVIAL MEMBRANE ARTICULAR CARTILAGE

4

5 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

6 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

7 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

8 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

9 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

10 Special Movements супінація і пронація Протракція (висування)
Ретракція (засування)

Skeletal System Joint Notes Joints perform two functions 1. 1. Hold bones together 2. 2. Allow rigid skeleton some flexibility so movement can occur.

Joints & Movements.
 Where two bones interconnect  400 + joints  Approximately 230 movable and semi-movable joints  The structure of a joint determines the type and amount.
