| Question | Answer |
| Cranial Vault Vs. Cranial Base development | Vault: develops from membranous bone. Base: develops from cartilaginous bone. |
| Unpaired bones of the vault | 1.Occiput. 2.Sphenoid. |
| Paired bones of the vault | 1.Frontal (meptopic suture). 2.Parietals. 3.Temporals. |
| What all does the cranial vault consist of? | 1.frontal bone. 2.Parietal bones. 3.squamous portion of the occipital bone. 4.Greater wing of the sphenoid bone. 5.Temporal bones. |
| What motions will occur between the unpaired/midline bones of the vault? | Flexion & extension. |
| What motions will occur between the paired bones of the vault? | Internal & External rotation. |
| Flexion of midline bones cuases what in paired bones? | External Rotation. |
| Extension of midline bones causes what in paired bones? | Internal Rotation. |
| What does the occiput articulate with? | 1.Atlas (at condyles). 2.Sphenoid (synchondrosis). 3.Parietal bones (lambdoidal suture). 4.Temporal bones (occipitomastoid suture). |
| What does the sphenoid bone articulate with? | 1.Occiput (SBS). 2.Temporal bones (petrous part). 3.Ethmoid (anteriorly). 4.Palatine bones (Inferiorly). 5.Frontal bone. 6.Vomer (inferiorly). |
| which wings of the sphenoid articulate with the frontal bone? | BOTH |
| Dysfunction patterns of Occiput | 1.Injury to O-A joint. 2.Trauma to Occiput. 3.muscle dysfunction of suboccipital muscles. 4.Sutural restrictions with temporal and parietal bones. |
| Dysfunction patterns of sphenoid | 1.Linkage to CN I-VI. 2.Endocrine problems. 3.Trauma with forceps delivery. |
| What does the Frontal bone articulate with? | 1.Parietals. 2.Ethmoid. 3.Both wings of sphenoid. 4.Lacrimal & nasal bones. 5.Zygomatic bone. 6.Maxillary bone. |
| What has inferior attachments to the frontal bone bilaterally? | Falx Cerebri. **Attaches at Fronto-ethmoidal articulation |
| When do the frontal sinuses form? | ~6y/o |
| Movement of frontal bone | 1.Flexion: Down, opening at bregma. 2.Extension: Up, closing and becoming flatter. |
| Overlaping order of the 4 bones articulating at the Pterion | Deep to superficial: 1.Frontal. 2.parietal. 3.sphenoid. 4.temporal. **wedging the frontal bone inside others will restrict spehnoid and thus SBS. |
| Treatment for Frontal bone SD | Frontal Lift: mobilizes the frontal bone, freeing up the flax cerebri. **Helps free up sutures, frontal sinus congestion, and frontal headaches. |
| What bones do the parietal bones articulate with? | 1.Contralateral parietal bone. 2.Sphenoid. 3.Temporal. 4.Occipital. 5.Frontal. |
| What bone encloses the anterior and posterior divisions of the middle meningeal artery? | Parietal bones |
| What bone covers the motor cortex? | Parietal bones **located in parietal lobes. |
| Parietal bones motion | 1.Internal rotation (w/ ext): Opens up in the center at sagital suture, inferior portion moves inward. 2.External rotation (Flexion): fold down about sagital suture, inferior portion moves outward. |
| Treatment for parietal bone SD | Parietal Lift: helps with hypertensive headaches, impulsive/aggressive children, idiopathic epilepsy, enhances drainage from superior sagittal sinuses. |
| What bones do the Temporal bones articulate with? | 1.Sphenoid (at petrous part). 2.Occipital (occipitalmastoid suture). 3.Parietal (superiorly). 4.Zygoma. 5.Mandible. |
| Temporal bones motion | 1.Internal rotation (w/ extension): mastoid processes move outward. 2.External rotation (w/ flexion): mastoid processes move outward. |
| What bone should be checked in a patient with torticollis? | TEMPORAL BONE. **SCM attaches to mastoid process. |
| Temporal bone axis of rotation is parallel to the ________? | Ext Aud. Canal |
| What is the most common dysfunction seen with temporal bone SD? | Vertigo |
| SD of what bone causes strabismus? | TEMPORAL (extraocular CN are in contact with temporal bone). |
| Other common temporal SDs | 1.Dyslexia. 2.TMJ. 3.Eustachian tube. 4.CNVII and CNVIII. |
| Treatment for temporal SD | Temporal balancing through decompression |
