Paired Bones Lab And Lecture Flashcards
What are the 5 bones the parietal bone articulates with?
Parietal, occiput, temporal, sphenoid and frontal
What bone is the only bone to contact all 4 fontanelles?
Parietal
What 3 things of importance do we find on the inner surface of the parietal bone?
Sagittal sinus, transverse sinus, and middle meningeal artery
Explain the motion of the parietal bone during cranial flexion?
External rotation. Bottom moves lateral. Top moves medial and down.
What is cranial synostosis?
Premature closure of a cranial suture
What two sutures are often involved in tension headaches?
OM and asterion
What suture is most commonly involved in synostosis?
Sagittal
What bone is the attachment for the tentorium?
Temporal
What does an internally rotated temporal bone and externally rotated temporal bone cause?
High pitched ringing and low pitched ringing
What is the relationship between the temporal bone moving and the Eustachian tube?
Internal rotation of the temporal bone will put pressure on the E tube.
3 mechanical/pain manifestations of Temporal Bone SD?
TMJ, head pain, and neck pain
What are the 5 organ/nerve/muscle problems because of temporal SD?
Dizziness, ear infections, swallowing and chewing problems, ringing in the ear, and Bell’s palsy because of CN7
What bone moves the frontal bone and what bone moves the temporal bone during flexion and extension of the cranium?
Sphenoid moves frontal and occiput moves temporal
What is the one mechanical symptom of frontal bone SD and what are the 4 organ, nerve, muscle problems because of frontal SD?
Head pain.
Sinusitis, visual problems, anosmia, and frontalis muscle tenderness
What is bracycephaly?
Fusion of the entire coronal suture so a shorter head as far as ap diameter.
