Question 2

bones of the viscerocranium

Answer 2

maxilla palatine vomer inferior nasal conchae lacrimal nasal zygomatic mandible hyoid

Question 3

maxilla

Answer 3

helps to chew
thin and delicate
intramembranous ossification

Question 4

alveolar process

Answer 4

horizontal portion of maxilla that holds the tooth roots

Question 5

alveoli

Answer 5

individual tooth sockets

Question 6

nasal (pyriform) aperature

Answer 6

nasal cavity formed by both right and left maxillae
nasal margin on midline

Question 7

frontal process

Answer 7

superior projection of nasal aperature medial to orbital margin
articulates with frontal, nasal, lacrimal, and ethmoid bones

Question 8

anterior lacrimal crest

Answer 8

vertical crest on lateral aspect of frontal process
marks anterior extent of lacrimal groove
combines with lacrimal bone to form lacrimal canal
drains tears into nasal cavity

Question 9

lacrimal canal

Answer 9

groove next to anterior lacrimal crest

Question 10

zygomatic process

Answer 10

lateral projection of bone for articulation with zygomatic bone
forms majority of the cheek

Question 11

canine fossa

Answer 11

depression on the facial surface just below the infraorbital foramen
above the canine

Question 12

maxillary sinus

Answer 12

hollow, air filled mucous lined cavity
largest of paranasal sinuses
housed in the body of the maxilla

Question 13

infraorbital foramen

Answer 13

foramen below the orbit
located below inferior orbital margin on facial surface

Question 14

inferior orbital fissure

Answer 14

located posterior to infraorbital sulcus
formed between greater wing and maxilla

Question 15

palatine process

Answer 15

hard bony roof of the mouth

Question 16

incisive foramen

Answer 16

on midline of palatine surface

Question 17

intermaxillary/interpalatine surface

Answer 17

splits palatine process in half

Question 18

horizontal plate

Answer 18

forms 1/3 of hard palate
carries greater and lesser palatine foramina (canals) == greater is more anterior, lesser is more posterior

Question 19

posterior nasal spine

Answer 19

located on superior surface of horizontal plate

Question 20

perpendicular (vertical) plate

Answer 20

next to maxillary sinus

Question 21

pyramidal process

Answer 21

posterior projection of vertical plate

Question 22

inferior nasal conchae

Answer 22

turbinates
paired bones inside nasal chamber

Question 23

vomer

Answer 23

unpaired bone along midsagittal plane
apart of nasal septum

Question 24

vomer perpendicular plate

Answer 24

forms nasal septum

Question 25

vomer alae

Answer 25

wings
located at base

Question 26

nasal bones

Answer 26

small, thin, delicate rectangular bones that form top of nasal aperature
located below glabellar region
nasal foramen transmits small vein

Question 27

lacrimal bones

Answer 27

paired bones
small, thin fragile bones of irregular shape that form top of nasal aperature
medial wall of eye orbit, anterior to ethmoid

Question 28

lacrimal groove

Answer 28

forms posterior portion of the superior end of the lacrimal canal

Question 29

zygomatic bones

Answer 29

paired bones that form the lateral midface (cheek)
frontal process, maxillary process, temporal process, inside eye orbit (articulates with sphenoid)
