facial bones

Question 1

inferior nasal conchae

Answer 1

thin bones projecting from the nasal cavity

Question 2

lacrimal bones

Answer 2

• in the eye socket
• the lacrimal sac can be punctured during tissue building

Question 3

mandible

Answer 3

• largest bone of the face
• this is a check point for facial curvature

Question 4

angle of the mandible

Answer 4

• widest part of the jaw
• where the ramus joins the inferior border of the body of the mandible
• it influences the form of the head from a frontal view
• measurement is similar to the distance between zygomatic bones

Question 5

ramus

Answer 5

• vertical portion of the mandible
• has the mandibular condyle and coronoid process

Question 6

coronoid process

Answer 6

• located on the mandible
• shaped like a crow beak
• the anterior process of the ramus to which the tempolaris muscle attaches

Question 7

mandibular condyle

Answer 7

• located on the mandible
• posterior process of the ramus
• rounded eminence at the articulation end of the mandible
• goes in the mandibular fossa

Question 8

body (of the mandible)

Answer 8

• part of the mandible
• the horizontal portion
• has the alveolar margin which holds your teeth

Question 9

alveolar process

Answer 9

• on the mandible
• holds 16 sockets for teeth
• inferior set of teeth sets lightly with those of the maxilla (affects surface contour)
• loss of teeth will change appearance

Question 10

mandibular symphysis

Answer 10

• on the mandible
• vertical line found along the midline on the body of the mandible
• two portions meet at a 110 degree angle

Question 11

mental protuberance

Answer 11

• on the mandible
• triangular, midline elevation found along the external surface of the body of the mandible.
• contributes to the formation of the prominence of the chin and its continuous: superiorly with the mandibular symphysis

Question 12

mental tubercle

Answer 12

• on the mandible
• paired bony prominence on each side of the mental protuberance

Question 13

alveolar crest

Answer 13

• on the mandible
• between the mental eminence and incisor teeth
• surface recedes
• responsible for recession of central plane of lower integumentary lip

Question 14

maxilla

Answer 14

• two fused bones
• there are three processes (frontal, palatine, zygomatic)
• holds the top teeth

Question 15

nasal spine

Answer 15

• in the maxilla
• used to anchor mouth closure
• the 2 maxilla bones fuse to form inferior margin of the nasal cavity
• send out a small sharp spur
• projection creates bony anatomical limit of the nose

Question 16

alveolar margin (process)

Answer 16

• in the maxilla
• thickest and most spongy part of the maxilla
• sockets of 16 teeth
• in adulthood its vertical dimension is increased due to development

Question 17

frontal process

Answer 17

• in maxilla bone
• extends superiorly and anteriorly besides a nasal bone
• articulates with frontal bones
• forms most of lateral margin of nasal cavity and medial margin of orbital cavity
• influences the lateral wall of the nose
• most anterior portion of the cheek

Question 18

incisive fossa

Answer 18

• in the maxilla
• boney depression in the central front area of the undersurface of the bony hard palate, directly behind the incisors

Question 19

palatine process

Answer 19

• in the maxilla
• forms greater part of the roof of the mouth
• floor of the nasal cavity
• not a surface bone
• has influence on the surface form

Question 20

zygomatic process

Answer 20

• in the maxilla
• elongated triangular structure
• just forward to join surface of zygomatic bone
• provides direction of anterior natural concavity of the cheek

Question 21

nasal bones

Answer 21

• creates the bridge of the nose
• articulation of the two
• anchor cartilage
• lies directly inferior to the glabella
• frontal and lateral surfaces widen as they descend

Question 22

vomer bone

Answer 22

inferior portion of the nasal septum

Question 23

zygomatic bones

Answer 23

• further part of cheeks
• like a diamond
• creates prominence of the cheek
• determines width of anterior plane of face
• greatest width of anterior plane of face
• ***but the zygomatic arch is the greatest width

Question 24

temporal process

Answer 24

• part of zygomatic bone
• surface of a zygomatic bone that articulates with the zygomatic process of the temporal bone
• creates arch of the cheek

Question 25

frontal process

Answer 25

- part of the zygomatic bone - articulates with the frontal bone - creates the lateral border of the eye socket

Question 26

maxillary process

Answer 26

- part of the zygomatic bone - articulates with the maxilla - on the inferior and medial region and creates the inferior and lateral border of the eye socket

Question 27

infants skulls

Answer 27

- 1/4 of body length - face makes 1/8 of skull - more bulbous frontal and parietal bones - fontanelles - thinner bones

Question 28

elderly skulls

Answer 28

- loss of mass - larger eye sockets - reduction in angle of the brow, nose, and maxilla - increase in the angle of the jaw to 140 degrees

Question 29

race in relation to skulls

Answer 29

- some differences but slight - caucasian, native american, asian, african
