Flashcards in Chapter 9 Somatic Dysfunctions Deck (17):
1

Axis/plane of motion in torsion?

AP axis, coronal plane

2

Torsion motions?

Sphenoid rotates one direction about AP axis, occiput rotation in opposite direction

3

How are torsion SDs named?

Named for greater wing of sphenoid that is more superior

4

Axes of motion in SB/rotation?

Rotation about an AP axis thru SBS; sidebending about 2 parallel vertical axes--one passing thru foramen magnum and other thru center of sphenoid

5

SB/rotation motions?

Sphenoid and occiput rotate in SAME direction (unlike torsion) and sidebending about the vertical axes causing deviation of SBS to either right or left

6

Sidebending to left will cause what rotation?

Sphenoid and occiput will rotate so that they are inferior on the left

7

Sidebending causes the SBS to deviate which way?

Right SB causes deviation of SBS to right and vice versa

8

Extension causes what motion of SBS?

SBS will move caudad

9

Flexion causes what motion of SBS?

SBS will move cephalad

10

What is vertical strain?

When sphenoid deviates cephalad or caudad in relation to the occiput

11

Axes of motion in vertical strain?

One tranverse axis thru center of sphenoid, other transverse axis just superior to occiput

12

What is lateral strain?

Sphenoid deviates laterally in relation to occiput

13

Axes of motion in lateral strain?

One vertical axis thru center of sphenoid, one vertical axis thru foramen magnum

14

Compression?

When sphenoid and occiput are pushed together causing decreased amplitude of flexion and extension

15

Cause of compression?

Trauma to back of head--if severe enough can obliterate CRI

16

Site of vagal SD?

OA, AA, C2 dysfunction

17

Cause of poor suckling in newborn?

Condylar compression (CN XII) and dysfunctions of CN IX and X at jugular foramen
