- 1Articulation (joint)occurs whenever two or more bones meet
- 2What are the classifications of articulation?structural and functional
- 3Three main structural categories of articulation:A) Fibrous
B) Cartilaginous
C) Synovial - 4Functional classes of articulation:A) Synarthrosis
B) Amphiarthrosis
C) Diarthrosis - 5Define fibrous joints and name three typesbones joined by fibrous connective tissue
suture, syndesmosis, gomphosis - 6Define suturesBones are jointed by short fibers which are later replaced by bone (becoming a synostosis)
- 7What are the soft spots in infants that hold bones together?fontanels
- 8SyndesmosisBones are joined by a band of fibers called a ligament, or interosseous membrane
- 9GomphosisShort fibers of the periodontal ligament bold teeth to alveolar socketsAre immovable joints
- 10Cartilaginous Jointsbones are held together by a cartilage. Can be immovable (synarthosis) or slightly movable (amphiarthrosis)
- 11Two types of Cartilaginous JointsSynchondrosis and Symphysis
- 12Synchondrosisbones held together by hyaline cartilage. Immovable (synarthrosis)
- 13Name examples of synchondrosisepiphyseal plate
sternum/first rib - 14Symphysisbones are connected by fibrocartilage.
Slightly moveable (amphiarthrosis) - 15Examples of SymphysisIntervertebral discs
Symphysis pubis - 16Synovial Jointsbones are separated by a fluid filled space
freely moveable (diarthrosis) - 17Components of Synovial Joints1) Joint capsule
2) Articular cartilage
3) Synovial Cavity
4) Reinforcing ligaments
5) Menisci - 18Intrinsic (Capsular) Ligamentsthickened portions of the articular capsule
- 19Extrinsic (Extracapsular) ligamentsexternal to the joint capsule
- 20Intracapsular Ligamentdeep to the joint capsule
- 21Functions of Menisci- helping to protect articular surfaces
- helping to improve the fit of the articular
surfaces that are not congruent - 22Bursaeflattened fibrous bags lined with synovial membrane, found where tendons, ligaments, muscles, skin, or bones rub together
- 23Tendon Sheathsfunction like bursae; elongated and wrapped around tendons
- 24Range of Motionthe movement that takes place at a joint
- 25Non-axialnon-directional movement; slipping movements only
- 26Uniaxialmovement in one plane
- 27Biaxialmovement in two planes
- 28Multiaxialmovement in three planes
- 29Gliding movementswhen flat or nearly flat articular surfaces slip or glide over each other
- 30Angular movementsthe angle between two bones increases or decreases
- 31Flexionmovement in a sagittal plane so that the angle between bones is decreased
- 32Extensionmovement into anatomic position from a flexed position
- 33Hyperextensionextension beyond anatomic position
- 34Abduction/Adductionmovement in a frontal (coronal) plane
- 35Circumductionmovement of a limb where the distal end traces a circle
- 36Rotationturning a bone about its long axis
- 37Supination/Pronationrotating movements of the forearm
- 38Inversion/Eversionrotating movements of the foot
- 39Six categories of synovial joints1) Plane (gliding, arthrodia)
2) Hinge (ginglymus)
3) Pivot (trochoid)
4) Condyloid (ellipsoid)
5) Saddle (sellaris)
6) Ball and Socket (spheroid) - 40Glenoid labrumrim of fibrocartilage that deepens the glenoid cavity
- 41Corcaohumeral ligament, glenohumeral ligaments providesome support
- 42Rotator Cuffs:subscapularis muscle, supraspinatus
muscle, infraspinatus muscle and teres minor (SITS muscles) - 43Acetabular labrumrim of fibrocartilage that deepens the acetabulum
- 44Iliofemoral, pubofemoral, isiofemoral ligaments providesome support
- 45Disorder of Joints1) Osteoarthritis
2) Rheumatoid arthritis
3) Gouty arthritis
4) Dislocation
5) Bursitis
6) Tendinitis
7) Sprain
