1

Nasal Bones

form bridge of nose.

2

Ethmoid Bone

Cribiform Plate &Crista Galli

3

Crista Galli

cock's comb. Vertical projection, point of attachment for dura matter.

4

Cribiform Plate

bony plates lateral to crista galli

5

Vomer Bone

Blade shaped bone. forms posterior/ inferior nasal septum

6

Palatine Bones

paired bones posterior to palatine processes. forms posterior hard palate and part of orbit. meet at median palatine process

7

Hyoid Bone

Located in the throat above larynx. Horseshoe shaped. Point of attachment for tongue/ neck muscles.

8

Sphenoid Bone

Keystone of cranium. superior orbital fissure,greater/lesser wings, sella turcica, optic fissue (canal)

9

Superior Orbital Fissures

jagged openings in orbit. provides passage for cranial nerves III, IV, V, and VI.

10

Greater Wings

Larger portion of sphenoid bone exteriorly anterior to temporal. forms part of eye orbit.

11

Lesser Wings

Bat shaped portion of sphenoid anterior to sella turcica

12

Sella Turcica

Turk's Saddle. saddle shaped region in sphenoid midline.

13

Optic Foramen

circular hole through which optic nerve passes.

14

Lacrimal Bone

fingernail sized bone. forms medial orbit walls between maxilla and ethmoid

15

Coronal Suture

Point of articulation of parietal bones with the frontal bone

16

Sagittal Suture

Mid-line articulation point of the two parietal bones

17

Squamosal Suture

Point of articulation of the temporal bone with the parietal bone.

18

Lambdoidal Suture

Point of articulation of the occipital bone and the parietal bones.

19

Anterior Fontanelle

Soft stop on top of skull. just forward of center.

20

Posterior Fontanelle

soft spot on the back of the skull

21

Vertebrae

24 single bones &2 fused. Makes up vertebral column.

22

Body of vertebrae

AKA Centrum. Rounded central portion of vertebrae. faces anteriorly in human vertebral column.

23

Sphenoidal Fontanelle

soft spot near temporal bone

24

Mastoid Fontanelle

soft spot between temporal and occipital bones

25

Vertebral Foramen

Opening enclosed by the body and vertebral arch. Passageway for spinal cord.

26

Transverse Processes

Two lateral projections from vertebral arch

27

Spinous Process

Single medial and posterior projection from vertebral arch.

28

Lamina

connects transverse and spinous processes

29

Pedicle

protrudes off body to become superior articular facet

30

Superior Articular Surfaces

Allows for articulation with vertebra above

31

Inferior Articular Surface

Allows for articulation with vertebra below

32

Cervical Vertebra

Upper most 7 vertebrae. Include axis and atlas

33

Transverse Foramen

Holes in transverse process in cervical vertebra

34

Atlas

C1. No body. Lateral processes contain large concave depressions that receive occipital condyles of skull. "Yes" movement.

35

Axis

C2. Pivot for rotation of axis. "No" movement.

36

Dens/Odontoid Process

Pivot point for rotation of axis.

37

Thoracic Vertebra

12 vertebra below cervical. Articulate with ribs.

38

Costal Facets

Articulate with the head of the rib.

39

Lumbar Vertebra

5 below thoracic. Lower back

Articulate with coccyx

42

Sacral Promontory

Top of sacrum. articulates with lumbar.

44

Lateral Sacral Crest

Dorsal side. Bumps off midline that would be transverse processes if not fused.

45
