different types of joints
synovial
cartilaginous
fibrous
types of fibrous joints
syndesmoses- unites bones with fibrous sheet
sutures- between bones of skull
fontanelles- wide sutures in neonatal skull
what is moudling?
Make’s the baby’s head smaller for passage through the birth canal-allows the growing frontal, parietal, temporal and occipital bones to ‘slide’ over each other
types of cartilaginous joints
primary cartilaginous - synchondroses- hyaline
secondary cartilaginous- symphyses- fibrocartilage
what are the 2 components of secondary cartilaginous joints?
outer fibrous- annulus fibrosus
inner soft- nucleus pulposus
what is the periosteum?
periosteum
- fibrous connective tissue ‘sleeve’
- vascularised
what are the subtypes of the synovial joints?
pivot
plane
hinge
bi-axial
ball and socket
what is the order of mobility in joints?
synovial>cartilaginous>fibrous
what is subluxation
reduced area of contact between articular surfaces
what is dislocation?
complete loss of contact between articular surfaces
