Question 8

The sphenoid bone and the ethmoid bone typically move in…

Answer 8

Opposite directions of each other

The vomer will move in the same direction as the __________

Answer 12

When the SBS is in flexion

The vomer will move in the same direction as the sphenoid

*Vowels move together, consonants move together

Question 13

Describe the vault contact

Answer 13

1. Index fingers = greater sphenoid wings
2. Middle fingers = anterior to ear
3. Ring fingers = mastoid process
4. Pinky fingers = occiput
5. Thumbs = frontal

Question 14

What is an SBS lateral strain named for?

What is it?

Answer 14

Named for the direction of the base of the sphenoid

Question 15

What is the direction of motion for the SBS lateral strain?

Answer 15

Both the sphenoid and occiput move in the SAME DIRECTION

Question 16

How is a vertical strain named?

Answer 16

Named for the direction of the base of the sphenoid

Question 17

What are the axes for vertical strains?

Answer 17

Transverse

Question 18

What type of strain is this?

“1st fingers move toward the practitioner, pinky fingers move away from practitioner”

Answer 18

Inferior strain

(It’s like the head rolls back into lap)

Question 19

What type of strain is this?

“1st fingers move away from practitioner, pinky fingers move toward practitioner”

Answer 19

Superior strain

(It’s like your hands are rolling forward and away from you)

Question 20

How are SBS torsions named?

Answer 20

Named for the higher greater wing of the sphenoid

Question 21

What is the motion that occurs in a SBS torsion?

Answer 21

Motion happens in opposite directions about this axis

Question 22

Describe that palpation you would feel in a torsion SBS SD

Answer 22

1st finger and pinky of one hand move superiorly

While the other hand moves inferiorly

Question 23

Whta is the sidebending rotation SBS SD named for?

Answer 23

Named for the convexity developed in the cranium

(Side of fullness)

Question 24

What motion occurs for a sidebending rotation SBS SD about the axes?

Answer 24

Motion happens in the SAME direciton about the SAGITTAL axis

Motion happens in the OPPOSITE direction on the VERTICAL axis

Question 25

Describe what you'd palpate in a **sidebending rotation SBS SD**

Answer 25

Named for the side that feels "fuller" = 1st finger and pinky move **away from each other** Opposite side "shrinks" = 1st finger and pinky move **toward each other**

Question 26

What is a **compression SBS SD?**

Answer 26

Significant trauma SBS is compressed

Question 27

How can you remember which way sacral **nutation** is?

Answer 27

Sacral base goes toward the **nuts** (Anterior)

Question 28

SBS flexion causes sacral \_\_\_\_\_\_\_\_\_\_\_ SBS extension causes sacral \_\_\_\_\_\_\_\_\_\_

Answer 28

SBS flexion causes sacral **COUNTERNUTATION** SBS extension causes sacral **NUTATION**

Question 29

Where would trauma occur to cause a **lateral strain?**

Answer 29

Anterior or Posterior to the SBS

Question 30

Where would trauma occur to cause a **vertical strain?**

Answer 30

Superior or inferior to the SBS

Question 31

Where would trauma occur to cause a **torsion?**

Answer 31

Hit with a roll "Twisty motion"

Question 32

Where would trauma occur to cause a **sidebending rotation?**

Answer 32

Direct blow to one side

Question 33

What is the motion at the base of the sacrum in SBS flexion?

Answer 33

Counternutation

Question 34

What is the motion of the apex of the sacrum in SBS flexion?
