Module 4: Joints Flashcards
what is the term used to assess injurt, rehabilitation and disease?
Range of Motion (RoM)
what are the 3 structural classifications of joints?
- Fibrous
- cartiligous
- Synovial
what are the properties of fibrous joints?
- held together with collagen fibers
- no cavity
- little to no movement
what are the properties of cartilaginous joints?
- held together with cartilige
- little to slight movement
- no cavity
what are the properties of synovial joints?
- joint cavity present that is filled with synovial fluid
- has an articular capsule in the cavity
- wide range of movement
what are the 3 functional classifications of joints?
- synarthrotic (very little)
- amphiarthrotic (slight)
- diarthrotic (free)
which structure is synonymous with diarthrotic?
syonvial
what are the 3 main types of fibrous structure joints?
- syndemosis ligament (holds tibia and fibula together)
- suture (short, interlocking fibers of the skull)
- gomphosis (peg in socket of tooth in mandible)
qhat are the 2 main types of cartilaginous joints?
- synchondrosis ( the growth plates in long bones)
- symphsis ( pubic piece of cartilage)
what are the 6 main types of synovial joints?
- gliding/plane: non axial e.g. between vertebrae
- hinge: uniaxial e.g. elbow
- pivot: uniaxial e.g. C1 and C2 of spine (atlas and axis)
- ellipsoid/condylar: Biaxial e.g. metacarpophalangeal
- saddle: Biaxial pair of concave and convex area articulating e.g. carpomatacarpal joint (thumb)
- ball and socket: multiaxial (hip)
what functional classification is fibrous and cartilaginous joints (hint: 2)
- synarthrotic (no)
- ampiarthrotic (slight)
what are the different axis of joints?
- nonaxial: no movement, sliding bone
- monoaxial: 1 direction, ankle
- biaxial: 2 directions: thumb
- multiaxial: 3 directions: shoulder
what are the 3 main types od movement?
- gliding: intercarpal
- angular:
- rotation: shoulder
what are the 6 features of a synovial joint?
- articular cartilgae
- joint cavity
- articular capsule
- syonvial fluid and membrane
- ligaments
- nerves and blood vessels
what is joint accessory structure?
cushioning that help preserve the health of a joint
