crista galli

Front 15

These projections of the ethmoid bone help form the internal shape of the nasal cavity and create turbulence in inhaled air

Front 16

The olfactory branches inter the nasal cavity through this part of the ethmoid bone

Back 16

cribriform plate

Front 17

This facial bone is paired and has three processes that connect to temporal, maxillary and frontal bones and makes up the lateral wall of orbits

Back 17

zygomatic bone

Front 18

This bone has the
vertical plate
ala

Back 18

Vomer

Front 19

This is part of the nasal septum (inferior to perpendicular plate of ethmoid bone)

Back 19

Vertical plate

Front 20

This part of the vomer articulates with the perpendicular plate of the ethmoid bone and with sphenoid bone

Back 20

Ala

Front 21

This facial bone is paired and has a perpendicular plate and horizontal plate

Back 21

Palatine

Front 22

The perpendicular plate of the palatine bone does what

Back 22

projects vertically and forms part of the lateral walls of the nasal cavity

Front 23

The horizontal plate of the palatine bone forms what

Back 23

forms the posterior portion of hard plate in mouth

Front 24

This facial bone is paired and has processes for frontal, zygomatic, alveolar, and palatine bones and forms the medial wall of orbit, anterior nasal spine. Both sides fuse in the middle

Back 24

Maxillae

Front 25

This facial bone has the
condylar process
coronoid process
body
ramus
alveolar process
and mental protuberance

Back 25

Mandible

Front 26

This part of the mandible articulates with the temporal bone

Back 26

condylar process

Front 27

This part of the mandible is a muscle attachment site

Back 27

coronoid process

Front 28

This paired facial bone articulate with each other, frontal, and maxillae and forms the bridge of the nose

Back 28

nasal

Front 29

This is the smallest bone of the skull and forms medial wall of each orbit

Back 29

lacrimal

Front 30

This bone has no articulations and is an attachment site for muscles and ligaments

Back 30

hyoid bone

Front 31

Whats the purpose of the sinuses

Back 31

Makes bones lighter
gives resonance to voice
Has mucous lining that warms and humidifies air

Front 32

What bones of the skull contain sinuses

Back 32

frontal
ethmoid
sphenoid
maxillae

Front 33

What makes up the vertebral column?

Back 33

24 individual vertebral bones and then sacrum and coccyx

Front 34

Whats the function of the vertebrae

Back 34

1. support weight of head
2. maintain posture
3. transfer weight to legs
4. protect delicate spinal chord

Front 35

Name the general vertebrae markings

Back 35

body
spinous process
transverse process
vertebral foramen
superior and inferior articular proces

Front 36

What part of the vertebral bone attaches to muscle

Back 36

spinous process

Front 37

This is called atlas, has no body, allows us to shake head yes and wag from side to side

Back 37

C1

Front 38

Called the axis. Allows us to shake head no

Back 38

C2

Front 39

This type of vertebrae have has a foramen in the middle of the transverse process

Back 39

cervical vertebrae

Front 40

These cervical vertebrae have a bifid spinous process

Back 40

C2-C6

Front 41

This type of vertebrae has costal facets which articulate with ribs on body and on transverse process. Have 12 vertebrae and 12 corresponding rib pairs

Back 41

Thoracic vertebrae
T1-T12

Front 42

This type of vertebrae is the largest and has really large spinous process

Back 42
