Joints Flashcards
joint
point of contact between 2 or more bones
point of contact between bone and cartilage
point of contact between teeth and bone
arthrology
study of bones
kineseology
study of movement
synovial cavity
point where 2 bones meet
fibrous joint
strong
bones held together by fibrous CT
suture joint
fibrous joint that has a thin dense layer of fibrous CT holding 2 bones together
example of a suture joint
cranial bones
sagital suture
connects both parietal bones to each other
squamosal suture
connects parietal bone to a temporal bone
lamboid suture
connects parietal bones to occipital bones
syndomosis
sheet of fibrous CT that joins 2 bones
interoseosmembrane
found between fibula and tibia
synarthrosis
no movement at the joint
gomphosis
fibrous CT
periodontal ligament
fibrous CT for teeth
amphiorthrosis
small amount of movement
diarthrosis
freely moveable joint
all synovial joints
cartilaginous joint
CT is hyaline or fibrocartilage
synchondrosis
connecting material is hyaline cartilage
example of sychondrosis
epiphyseal plate
symphysis joint
connecting material is a disc of fibrocartilage
articular capsule
outer layer- dense irregular CT
inner later- synovial membrane
synovial fluid
similar to plasma
has phagocytes
lubricates the joints
tibiofemoral joint
femur/tibia
patellofemoal joint
femur/patella
what is the function of fibrocartilage discs in the knee
allows bones to fit snugly together
provides stability
circulates synovial fluid
what are the accessory ligaments in the knee
extracapular ligament
intracapsular ligament
