joints Flashcards
a point of contact between two or more bones
articulation
permits very little to no movement
synarthrotic
joint allows a limited amount of movement
ampiarthrotic
a freely moveable articulation
diarthrotic
dense CT; little or no movement; bones of skull; interosseous membrane b/w radius and ulna (syndesmosis) teeth sockets (gomphosis
FIBROUS, synarthrotic
permits little to no movement; held together by hyaline cartilage or fibrocartilage
CARTILAGINOUS, amphiarthrotic
type of diarthrotic joint
synovial
ring shaped piece of fibrocartilage
articular disc
small synovial membrane pillow filled with synovial fluid
bursae
adipose tissues to thicken their joint capsules
fat pad
smooth CT; reduces friction bt bones
hyaline carilage
acts as a container for the joints contents, blends into the periosteum and bone
joint capsule
like an articular disc enhances the available surface area, provides stability
labrum
dense strap of CT stabilizes and limits mobility of a joint
ligaments
thin membrane; produces synovial fluid, lubrication of articular surfaces reduces friction
synovial membrane and fluid
irregular, only allow movement through gliding and slipping (3)
acromioclavicular
intercarpal
intertarsal
NONAXIAL
only allow movement in one direction (uniaxial)
HUMEROULNAR TIBIOFEMORAL TALOCURAL FINGER,THUMB TOE HINGE HINGE HINGE
only allow rotary movements
radioulnar
atlantoaxial
PIVOT
codyloid, saddle
convex into concave
radiocarpal MCP, MTP occipitoatlantal CMC ELLIPSOID AND SADDLE JOINT BIAXIAL
triaxial, ball and socket
glenohumeral
hip-femoro-acetabular
