what is synovial fluid
a slippery fluid that his contained within the joint cavity
function of synovial fluid
to reduce friction between the articular cartilage in the joint
what is the articular cartilage
glassy-smooth cartilage that is spongy and covers the ends of the bones in the joint
function of articular cartilage
to absorb shock and prevent friction between the ends of bones in the joint
what is the joint capsule
tough fibrous tissue that has tow layers
-fibrous capsule lying outside the synovial membrane
function of joint capsule
fibrous capsule-help strengthen the joint
synovial membrane-lines the joint and secretes synovial fluid
strain vs sprain
strain=muscles
sprain=ligaments
eg of long bone
femur
tibia
fibula
phalanges
eg of short bone
carpals
