what are the 2 major classifications of joints
synarthroses (non-synovial)
diarthroses (synovial)
types of synarthroses
- synostosis
- syndesmosis or fibrous
- synchondrosis
synostosis
in skull, bone to bone
syndesmosis
bone that connects to bone via cartilage or fibrous connective tissue
synchondrosis
separated by hyaline or fibrocartilage. slight movement. provides stability
5 components of Diarthrosis joints
- fibrous joint capsule
- joint cavity
- synovial membrane
- synovial fluid
- articular (hyaline) cartilage
fibrous capsule of Joint Capsule
outer layer
attaches to periosteum
limited blood supply
contains jt. receptors
synovial membrane of Joint Capsule
inner layer
secretes synovial fluid
poorly innervated, good blood supply
Diarthrodial Joints
- planar
- hinge
- ball and socket
- bicondylar
- pivot
- saddle
- ellipsoidal
hinge joint
humeroulnar (elbow)
talocrural (ankle)
bicondylar joint
tibia femoral joint: felxion and extension and some rotation
pivot joint
radialulnar joint: supination and pronation
saddle joint (sellar)
convex on concave in one plane and concave on convex in another plane
ellipsoidal joint (condyloid)
knuckles: convex surface meets with concave surface
planar joint
AC joint, midtarsal, intertarsal, intercarpal
2 flat surfaces meeting with one another. gliding motion
uniaxial
motion occurs in one plane around single axis
toes and fingers
