what is a suture
joints between the cranial bones
what does the sagittal suture attach
the parietal bones
what does the coronal suture attach
the frontal bone and parietal bones
what does the lambdoid suture attach
parietal bones and occipital bone
what does the squamous suture attach
parietal and temporal bones
where is the bregma located
between the coronal and sagittal sutures
separates the frontal and parietal bones
anterior portion of skull
where is the lambda located
point the connects the lambdoid and sagittal sutures
posterior portion of skull
where is the pterion located
anteriorly
the meeting point of frontal, parietal, temporal and sphenoid bones
where is the asterion located
posteriorly
meeting point between parietal/temporal and occipital
on the cheek bone keep moving posteriorly the ear
where is the nasian located
where the 2 nasal bones and the frontal bone meet
what is a fontanel
soft spot between the sutures that hasn’t fully ossified
when does ossification occur in the frontal bones
18-24 months of age
what ossifies in order
posterior, sphenoid, mastoid, anterior
anterior(infants) bregma(adults
posterior(infants)(lambda(adults)
mastoid (infants) (asterion) (adults)
sphenoidal (infants) pterion (adults)
