Answer |
| What does the neurocrainum consist of? |
crainal vault and cranial base |
| What is the cranial vault? |
portiion of the skull that overlies the brain |
| What is the cranial base? |
portion which underlies the brain |
| What are the unpaired bones of the skull? |
sphenoid, occiput, ethmoid, mandible and vomer |
| How do unpaired bones move? |
like the gears ofa clock driven by SBS movement |
| What is the general movement of unpaired bones? |
flexion and extension |
| What are the movements of the paired bones? |
external and internal rotation |
| What does external rotation correspond with? |
SBS flexion |
| What does internal rotation correspond with? |
SBS extension |
| What are the paired bones? |
frontal, parietals, temporal, nasal bones, maxillae, zygomatic bones, inferior conchae, lacrimal bones and palatine bones |
| What does the cranial vault consist of? |
frontal, greater wings of sphenoid, squamous potions of temporal bones, two parietal bones and interparietal occiput |
| What are the sutures of the cranial vault? |
lambdoidal, occiptiomastoid, squamous, sphenosquamous, sphenofrontal and sphenoparietal |
| Which suture can you easily make people sick with? |
occiptomastoid suture |
| How do the four bones of the skull overlap? |
in alphabetical order form the inside to the outside of the skull |
| What are vault bones formed from? |
membrane |
| What are basilar bones formed from? |
cartilage |
| When is there no articular surfaces of sutures? |
before third year of life |
| What are the 3 components of motion in the vault bones? |
rotation, side bending and separation |
| What is rotation in reference to? |
individual axes |
| What is side bending in reference to? |
SBS |
| What 5 bones does the parietal bone articulate with? |
contralateral parietal, frontal, occiput, sphenoid and temporal |
| How does rotation of the parietal bone move? |
it follows the overlapping of the temporal bone |
| What is external rotation of the parietal bone? |
external rotation rotates about the axis to carry the sphenoid angle anterolaterally. The mastoid angle moves more laterally and anteriorly |
| How do somatic dysfunctions of the parietal bones include external and internal rotation? |
headaches, idiopathic epilepsy, local pain and children show impulsive aggressiveness |
| How do you treat parietal restricted movement? |
parietal lift |
| What 12 bones does the frontal bone articulate with? |
parietals (2), sphenoid, ethmoid, lacrimals (2), maxillae (2), nasals (3), and zygomatic bones (2) |
| How is the frontal bone able to act as a paired bone? |
metopic suture |
| How many axis does the frontal bone have? |
2 |
| How is the frontal bone rotated from external rotation? |
frontal bones are turned by the sphenoid in such a way that the zygomatic angles move forward and slightly downward |
| How do the posterial borders of the frontal bone move in external rotation? |
laterally to widen the ethmoid notch posteriorly |
| How do dysfunctions of the frontal bone present with? |
frontal headaches, frontal sinus problems, eye disturbances, nasal pathology and antisocial tendancies |
| How do you treat restricted frontal movement? |
frontal lift |
| What does each temporal bone articulate with? |
occiput, parietal, sphenoid, zygomatic bone and mandible |
| How does external rotation of the temporal bone present? |
rotation of the squamous portions diverge increasing the lateral diameter of the skull while the mastoid portions converge |
| How do temporal bone dysfunction present? |
hearing problems, Eustachian tube dysfunction, dizziness, tinnitus, bell’s palsy, trigeminal neuralgia, otitis media, jaw popping/TMJ syndrome |
| How is restricted temporal mobility treated? |
temporal decompression |
| How are paired bones rotated? |
internally and externally |
| What is V-spread technique? |
treatment for tenderness or vcranial bone restriction |
| How do unpaired/midnline bones move? |
flex/extend |
| In cranial motion, the vault ___________ the cranial base. |
follows |
| How is dysfunction of the cranial vault caused? |
prenatal, perinatal or incidental trauma and/or underlying strain patterns. |
