Axial Skeleton

Question 1

frontal bone

Answer 1

forehead

Question 2

supra orbital foramen

Answer 2

the hole above each eye, allows nerve to pass through the forehead

Question 3

parietal bones

Answer 3

2 of them on each side that form the superior and lateral skull.

Question 4

occipital bone

Answer 4

forms skulls posterior wall and base

Question 5

foramen magnum

Answer 5

in the base of the occipital bone; where the inferior part of the brain connects with the spinal cord. translates to large hole

Question 6

occipital condyles

Answer 6

rockerlike and articulate with the first vertebra of the spinal column in a way that allows us to say “yes”

Question 7

temporal bones

Answer 7

are inferior to the parietal bones and meet at the squamous sutures.

Question 8

external auditory meatus or canal

Answer 8

external ear canal where sound enters the ear

Question 9

zygomatic process

Answer 9

barlike, and meets the zygomatic bone of the face anteriorly.

Question 10

mandibular fossa

Answer 10

oval shape where the zygomatic process receives the condylar process of the mandible

Question 11

styloid process

Answer 11

needle like, attachment point for several tongue and neck muscles and ligament for the hyoid bone of the neck to the skull

Question 12

mastoid process

Answer 12

acts as an anchoring site for some neck muscles. it is the lump just posterior to the ear

Question 13

sphenoid bone

Answer 13

bat shaped bone that spans the width of the middle cranial fossa.

Question 14

lesser wing

Answer 14

hornlike an dorm part of the floor of the anterior cranial fossa and part of the medial walls of the orbits

Question 15

greater wing

Answer 15

project laterally from the sphenoid body forming parts of 1) the middle cranial fossa and 2) posterior walls of the orbits # the external wall of the skull and are medial to the zygomatic arch

Question 16

sella turcica

Answer 16

forms a snug enclosure for the pituitary gland

Question 17

ethmoid bone

Answer 17

lies between the sphenoid and nasal bones of the face and is the most deeply situated bone of the skull. forms the bony area between the nasal cavity and orbits

Question 18

crista galli

Answer 18

“roosters comb” the outermost covering of the brain attaches to this an helps secure the brain in the cranial cavity.

Question 19

cribriform plate

Answer 19

superiorly to the ethmoid; 2 plates that form the roof of the nasal cavity and the floor of the anterior cranial fossa. they have holes that allow for smell receptors to carry scents to the brain

Question 20

superior nasal conchae

Answer 20

Concha shell shaped features extending horizontally along the lateral walls of the nasal cavity.

Question 21

coronal sutures

Answer 21

where the parietal bones meet the frontal bone anteriorly

Question 22

sagittal sutures

Answer 22

where the parietal bones meet superiorly at the cranial midline

Question 23

squamosal suture

Answer 23

where a parietal and temporal bone meet on the lateral aspect of the skull

Question 24

lamboidal sutures

Answer 24

where the parietal bones meet the occipital bone posteriorly

Question 25

anterior fossa

Answer 25

supports the frontal lobes of the brain. it is the interior of the frontal bone

Question 26

middle fossa

Answer 26

cavity median to the parietal bones

Question 27

posterior fossa

Answer 27

internal side of the occipital bone which supports the cerebellum of the brain

Question 28

nasal bones

Answer 28

fused medially forming the bridge of the nose

Question 29

lacrimal bones

Answer 29

contribute to the medial walls of each orbit. they articulate with the frontal bone superiorly, the ethmoid bone posteriorly and the maxillae anteriorly. it contains a deep groove that forms a lacrimal fossa

Question 30

zygomatic bones

Answer 30

cheekbones

Question 31

maxillary bones

Answer 31

fused medially and form the upper jaw and central portion of the facial skeleton. considered the keystone bone of the facial skeleton

Question 32

infraorbital foramens

Answer 32

allows the infraorbital nerve and artery to reach the face. they are below the orbit

Question 33

palatine processes

Answer 33

form the anterior two thirds of the hard palate or roof of mouth (closest to the teeth)

Question 34

palatine bones

Answer 34

the other third of the hard palate, it is closest to the back of the mouth
