25
when does the face develop
7 weeks post conception a recognizable face
26
the least cleating possible is
bifid uvula
27
growth center is
represented by a suture | compensatory to external forces
28
post natal facial growth only occurs in
Surfaces Sutures, synchondroses condyles
29
what is the major mechanism of calvaria growth
Appositional growth at cutaneous & meningeal surface
30
cranial base and adjacent fosse growth is characterized by
Cortical drift and growth at the syndrondroses depending on age of subject
31
synostosis
early closure of cranial suture
32
the sphenoid-occipital synchondrosis grows
toward both occipital and sphenoid bone
33
the velocity cure is also called
incremental curve
34
sphenoid ethmoidal synchondrosis cease to grow at
7 years of age

which bone is endochondral only
Ethmoid Bone
37
which bones are mixed in origin
temporal , occipital, splendid
38
when does heart start beating
week 4
39
when do the 5 primodia of face develop
5 weeks pc
40
what are the 5 primordial of the face
``` eyes nasal pit maxillary process mandible arch oral opening ```
41
when is facial development complete
7 wks pc
42
why is the condyle not a growth center
``` 2ndary cartilage appositional growth not interstitial lacks structural organization cartilage implants dont grow different effect on chem and hormonal agents ```
43
bone spatial change is by 2 general processes
Cortical drift | Displacement
44
Hemifacial Microsomia
No condylar growth on L side
45
most common distribution of Cleft lip/ palate
cleft lip and palate
46
Both the maxilla and mandible grow downward and forward
False mandible does grow outward and forward
47
growth of mandible is
up and back
48
mandibular displacement
down and forward
49
what day does blastocyst form
8th day
50
when does neural tube begin closing
21 day starts in middle
51
neural crest ectoderm
responsible for carniofacial muscles and bone
52

Depth: 30-45% Height: 40-45% widthe: 55-60%
54
statue is divided into quarters
true
55
somatotypes
Ectomorph-skinny like spider legs ECto Mesomorph- Meso- mid sized Endomorph-(endo always means body this is FAT)

Gastrulation & production of mesoderm formation of notochord or head process Hensens node Primitive streak
65
regions where mesoderm is not interposed between ectoderm and entoderm
become phargeal and cloacal membranes
66
principal derivative of ectoderm is
nervous tissue / neural ectoderm
67
percent distribution if C/L P types
L-25% P=30%-chick mostly L&P-45%
68
