A
- part of the temporal bone
- connects to the zygomatic arch
- projects from lower part of the squama
- long and thin, extends anteriorly to the cheekbone
- determines the widest part of the face
25
the 2 interior bones of the cranium
- ethmoid
- sphenoid
26
ethmoid bone
- cribriform plate
- nose area
27
sphenoid bone
- shaped like a bat/butterfly
- mostly internal
28
inferior nasal conchae
- thin bones projecting from the nasal cavity
29
lacrimal bones
- in the eye socket
- the lacrimal sac can be punctured during tissue building
30
mandible
- largest bone of the face
- this is a check point for facial curvature
31
angle of the mandible
- 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
32
ramus
- vertical portion of the mandible
- has the mandibular condyle and coronoid process
33
coronoid process
- located on the mandible
- shaped like a crow beak
- the anterior process of the ramus to which the temporalis muscle attaches
34
mandibular condyle
- located on the mandible
- posterior process of the ramus
- rounded eminence at the articulation end of the mandible
- goes in the mandibular fossa
35
body (of the mandible)
- part of the mandible
- the horizontal portion
- has the alveolar margin which holds your teeth
36
alveolar process
- 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
37
mandibular symphysis
- on the mandible
- vertical line found along the midline on the body of the mandible
- two portions meet at a 110 degree angle
38
mental protuberance
- 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
39
mental tubercle
- on the mandible
- paired bony prominence on each side of the mental protuberance
40
alveolar crest
- on the mandible
- between the mental eminence and incisor teeth
- surface recedes
- responsible for recession of central plane of lower integumentary lip
41
maxilla
- two fused bones
- there are three process (frontal, palatine, zygomatic)
- holds the top teeth
42
nasal spine
- 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
43
alveolar margin (process)
- 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
44
frontal process
- in the maxilla bone
- extends superiorly and anteriorly besides a nasal bone
- articulates with frontal bone
- 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
45
incisive fossa
- in the maxilla
- boney depression in the central front area of the undersurface of the bony hard palate, directly behind the incisors
46
palatine process
- 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
47
zygomatic process
- in the maxilla
- elongated triangular structure
- juts forward to join surface of zygomatic bone
- provides direction of anterior natural concavity of the cheek
48
nasal bones
- creates the bridge of the nose
- articulation of the two
- anchor cartilage
- lies directly inferior to the glabella
- frontal and lateral surface widen as they descend
49
vomer bone
- inferior portion of the nasal septum
50
zygomatic bones
- 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
51
temporal process
- part of zygomatic bone
- surface of a zygomatic bone that articulates with the zygomatic process of the temporal bone
- creates arch of the cheek
52
frontal process
- part of the zygomatic bone
- articulates with the frontal bone
- creates the lateral border of the eye socket
53
maxillary process
- part of the zygomatic bone
- articulates with the maxilla
- on the inferior and medial region and creates the inferior and lateral border off the eye socket
54
male vs. female skulls
- male = more prominent supraorbital rim
- female = glabella is more subtle and is lighter with less defined curves bby
