[DSA] Midline Bone [Zaremski]

Question 1

What are the attachments of the cranium and the sacrum?

Answer 1

Dura of foramen magnum to dura of posterior body and disc of S2

Question 2

Deviation of the ethmoid spine may have what clinical effect on nasal passage?

Answer 2

Septal deviation => can only breathe through one nostril

Question 3

Ethmoid rotates about what axis?

Answer 3

Transverse axis

Question 4

Ethmoid extension moves the crista galli in what directions?

Answer 4

Inferior

Anterior

Question 5

Cranial extension has what effect on the ethmoid bone?

Answer 5

Extension

Internal rotation

Question 6

What role might the ethmoid bone play in sinusitis?

Answer 6

Lateral masses move into ER with widening of ethmoid notch and ER of maxillae => open nasal passage

ER/IR on ethmoid create pumping action on ethmoid sinus

Question 7

What role might the ethmoid bone play in HA?

Answer 7

Lymph backup may cause:

Increased dural tension => migraine/tension HA

Vascular effects => migraine

Question 8

What motion do the palatines move in during SBS flexion?

Answer 8

External Rotation

Question 9

What is the function of the vomer in cranial flexion?

Answer 9

Depress hard palate

• Flexion - wide flat palate*
• Extension - narrow tall palate*

Question 10

When SBS is in flexion:

Ethmoid moves in the same direction as the ______

Vomer moves in the same direction as the ______

Answer 10

Ethmoid moves in the same direction as the occiput

Vomer moves in the same direction as the sphenoid

• Vowels move together*
• Consonants move together*

Question 11

Somatic dysfunction of the vomer is usually secondary to ____

Answer 11

Trauma

Question 12

What are the clinical indications for treating palatine somatic dysfunction?

Answer 12

TMJ

Swallowing/speech difficulties

Question 13

What landmark does the auditory canal exit? What is the clinical consequence of dysfunction here?

Answer 13

Junction of the petrous portion of temporal and sphenoid Bs.

Otitis Media (lack of drainage)

Question 14

Distention, traction, or dilation of which arteries are known to cause HA?

Answer 14

Middle meningeal

Superficial temporal As.

Due to close relationship of dura to arteries

Question 15

External rotation somatic dysfunction of the temporal bone would put pressure on what structures?

Answer 15

Structures deep to the tentorium cerebri

Due to attachment at petrosal ridge

Question 16

How might OMT have an effect on Bell’s palsy?

Answer 16

Temporal bone alignment

Regional tissue strain release

Question 17

What was the result of OCMM performed in geriatric pts, dizziness pts, and college students according to the studies from the J Am Osteopath Association?

Answer 17

Geriatric - improved balance

Dizziness - less dizzy (wow)
