Flashcards in Axial Skeleton: Cranial and facial bones Deck (37):
1

Name the 6 cranial bones

Frontal, Occipital, Pariental, Temperal, Sphenoid, Ethmoid

2

Sphenoid

-internal (butterfly bone)
-Superior Orbital Fissura (split into eye)
-Sella Turcica (pituratary gland)
-Lesser greater wing
-Optic foramina
-rotundum foramen
-ovale foramen
-Lacerum Foramen

3

Temporal Bone

-Squamousal Suture (connecting pariental and Temporal bones
-Zygomatic process
- Mandibular fossa (dip in bone where the mandible connects
-External auditory meatus
-Styloid Process
-Mastoid Process
-Stylomastoid foramen
-Juglar foreman
-Carotid Canal

4

Frontal Bone

-supraorbital foramen
-coronal Suture

5

Ethmoid Bone

-Located inside the nose
-Crista Galli- sharp piece point superiour, anchor membrane for brain
-cribriforma Plate-the cristagalli attached-holy
-Olfactory forman Lacerum
-Perpendicular plate-septum
-superior and Medial Nasal Conchae
-Sinus

6

Occipital Bone

-Lambdoidal Suture (connecting occipital and parietal bone)
-Foramen magnum (large hole spinal cord meets brain)
-Occipital Condyles (articulates c1)
-Hypoglossal Canal (inside the foramen magnum)
-External occipital crest and protublerance

7

Parietal Bone

-2 L&R
-Sagittal Suture (above holding two together)
-Coronal Suture (down sides connecting to frontal)

8

typical features of vertabra

-body and arch (pedicle body, Lsminse between processes)
-Transverse process (lateral out each side, anchor muscles)
-Spinous process (center spine protrusion)
-Vertebral Foramen (formed by body and arch where spinal cord goes)
-Intervertebral foramina (hole between 2 vertebrae)
-Intervertebral disc (fibrocartilage)

9

3 main portions of the sternum

-manubrium (has juglar notch-dip in center)
-Body ( attaches ribs)
-Xiphoid process (cartilage tail turns to bone around 40)

10

Difference between true, floating, and false ribs

-True- 7- defined by having its own piece of cartilage attached to sternum
-False- 5- defined by sharing or absense of cartilage
- Floating- 2- no cartilage

11

Structure between vertabrea

intervertebral disc made of fibrocartilege

12

Vertebral regions

Cervical-7- Atlas and Axis
Thoratic- 12- Articulates with ribs
Lumbar-5- Large=support
Sacral- 5 fused= Sacrum
Coccygeal- 3 fused= Coccyx

13

Bones that contain Alveoli

-Maxilla
-Mandible

14

The structure that is housed in the sella turnica

the pituatary gland

15

The peg like process of c2

odontoid process- Dens
Allows head shaking how c1 and c2 connects

16

Name of c1 and c2 vertabre

Atlas-c1
Axis-c2

17

Bone that anchors tounge and why its unique

hyoid- b/c there is not articulation to another bone, kept in place by muscle tendenion

18

Bones that comprise the hard palate

Maxilla and the palatine process

19

The 7 bones that contribute to the orbit

-Frontal
-Sphenoid
-ethnoid
-maxilla
-palatine
-zygomatic
-lacrimal

20

Name the bones that comprise the nasal septum

-Vomer
-Perpendicular plate of the ethmoid

21

4 main cranial sutures and locations

-Coronal- connect frontal and parietal
-Squamous- connects temporal and parietal
-Lambdoid- connects occipital and parietal
-Sagittal- connects parietal bones down middle

22

Maxillary Sinus

-Largest most superior sinus

23

Ethmoidal Sinus

-Interior to frontal superior to sphenoid
-sinus
-small, multiple, behind eye orbit

24

Hyoid

-Horseshoe like
-interior to mandable
-no articulation, held in place by muscle
-tongue is anchored to this

25

Vomer

lower portion of nasal septum

26

Lacrimal

-2 bones (each side)
-Medial side of orbit
-Lacrimal Fossa- canal into nose (why our nose runs when we cry

27

Palatine

-Roof of mouth further back
-2 bones (L&R)

28

Mandible

-Coronoid Process (muscle attached to move jaw)
- Mandubular Condyle (attaches to Mandibular fossa of temporal bone)
-Rami- edge of mandible
-body
-Mandibular angle
-Alveolar margin
-Mandibular symphysis (chin)
-Mental formina (external)
-Mandibluar foramen (internal)

29

Bones that comprise the zygomatic arch

Zygomatic and temperal

30

Fontanels

Soft spots on fetal skeleton

31

Shenoid Sinus

-Superior to the maxillary
-interior/posterior to ethmoidal

32

Frontal SInus

top most superior above orbital

33

Inferior nasal concae

Creates more surface area

34

Nasal

Bridge of bone where glasses sit (2)

35

Zygomatic

Cheek Structure (2)

36

Maxilla

-Upper Jaw
-Alveoli
-Palatine process
-Infraorbital foramen

37

Name the facial bones (8)

Vomer 1, Maxilla 1, mandible 1, inferior nasal concha 1, Lacrimal 2, zygomatic 2, Palatine 2, Nasal 2
