Q

midline bones

A
occiput
sphenoid
mandible
vomer
ethmoid
frontal
2
Q

Paired bones

A
frontal
parietal
squamous temporals
squamous occiput
inferior nasal concha
lacrimal
maxilla
nasal
palatine
zygoma
frontal
3
Q

Midline bones

A

flexion/extension

usually rotate about a transverse axis in a anterior/posterior direction

4
Q

paired bones

A

internal/external rotation

usually move about AP axis in a lateral motion

5
Q

Ethmoid parts

A

horizontal - cribriform plate
perpendicular plate
lateral masses (2)

6
Q

Ethmoid flexion

A

rotates around a transverse axis
crista galli swings superiorly and posteriorly
lateral masses externally rotate(expand inferiorly)

7
Q

Ethmoid extension

A

rotates around a transverse axis
crista galli swings inferiorly and anteriorly
lateral masses internally rotate(compress inferiorly)

8
Q

5 articulations of the Vomer

A
nasal septum
ethmoid
sphenoid
palatines
maxillae
9
Q

Vomer flexion

A

rotates around a transverse axis
wide flat palate
posterior part depresses the palatine, flattening the roof of the mouth
anterior part ascends to allow premaxillae to externally rotate

10
Q

Vault Contact

A

Index fingers rest of the greater sphenoid wing, just posterior to the frontozygomatic suture
Middle fingers anterior to the ear on temporal
ring fingers rest on the mastoid process
pinky fingers rest on the occiput
palms may rest upon the parietals
thumbs may contact the frontal bone

11
Q

Lateral Strain Axis

A

Two vertical axis

12
Q

Lateral Strain Names

A

for the direction of the base of the sphenoid

13
Q

Lateral Strain Motion

A

motion happens in the same direction

14
Q

Lateral Strain Palpation

A

1st fingers move in opposite direction from pinky fingers

side of strain moves anteriorly

15
Q

Vertical Strain Axis

A

two transverse axis

16
Q

Vertical strain named

A

named for the direction of the base of the sphenoid

17
Q

Vertical strain motion

A

motion happens in the same direction

18
Q

Vertical strain palpation

A

superior - 1st fingers move away from practitioner, pinky fingers move toward practitioner
inferior - 1st fingers move toward the practitioner, pinky fingers move away from practitioner

19
Q

Torsion axis

A

one sagittal axis (AP)

20
Q

Torsion named

A

named for the higher greater wing of the sphenoid

21
Q

Torsion motion

A

motion happens in opposite directions about the axis

22
Q

Torsion palpation

A

1st finger and pinky of one hand move superiorly while the other hand moves inferiorly

23
Q

Sidebending rotation axis

A
one sagittal (AP)
two vertical
24
Q

sidebending rotation named

A

named for the convexity developed in the cranium

full side

25
Q

sidebending rotation motion

A

motion is in the same direction about sagittal axis

motion is opposite on the vertical axes

26
Q

sidebending rotation palpation

A

named side feels “fuller”
1st finger and pinky move away from each other and out.
opposite side “shrinks”
1st finger and pinky move toward each other and in

27
Q

compression axis

A

sagittal (AP)

28
Q

compression causes

A

significant trauma, depression, anxiety

may mimic other patterns

29
Q

location of trauma to cause lateral strain

A

A or P to SBS

30
Q

location of trauma to cause vertical strain

A

either in front or behind SBS on superior or inferior aspect of the head

31
Q

location of trauma to cause torsion

A

hit with a roll

32
Q

location of trauma to cause sidebending rotation

A

blow right to the ear

33
Q

axis of motion of the sacrum

A

superior transverse posterior S2
