Paired Bones Flashcards
The temporal bone’s main motion is…
rotation
temporal bone motion is driven by the occiput through OM articulation
C. Flexion
What are the paired bones?
SBS Flexion vs. Extension
What five bones does the parietal bone articulate with?
occiput
frontal
sphenoid
temporal
opposite parietal
What is the only bone that contacts all four fontanelles?
parietal bone
Parietal external vs. internal rotation
external rotation occurs with SBS flexion
What are s/s of parietal bone dysfunction?
- Cranial synostosis
- Head Pain: tension HAs, temporal HAs…
- Middle Meningeal Artery: trauma, giant cell arteritis…
- Head, face, tooth pain: temporal m. SD…
What is the most common synostosis?
sagittal - restricts transverse skull growth
Eustachian tube exit is b/t what two bones?
temporal and sphenoid
temporal internal rotation –> high pitched tinnitus
temporal bone external rotation –> low pitched tinnitus
What is unique about the newborn skull in regards to the temporal and occiput bones?
temporal - lacks mastoid process
occiput - five parts and malleable
What are s/s of temporal bone SD?
TMJ pain
head pain
neck pain
dizziness
ear infections
swallowing/chewing problems
tinnitus/eustachian tube dysfunction
bell’s palsy
What bone is considered paired in infancy, but singular in adulthood?
frontal bone
What is the axis/motion of the frontal bone?
What are the s/s of frontal bone SD?
focal/global head pain
frontalis m. SD
sinusitis
visual problems
anosmia
What synostosis is associated with syndromes like Apert, Muenke…?
Bicoronal Synostosis
What causes anterior plagiocephaly?
Unicoronal Synostosis
