elevations around placodes
lateral and medial aspects in relation to the nasal pits

Front 7

Maxillary Prominence growth pattern

Back 7

enlarge and grow medially from each side
fuses 1st w/ medial nasal prominence, 2nd w/ lateral nasal prominence

Front 8

Nasolacrimal Groove

Back 8

cleft b/t maxillary prominence and lateral nasal prominence

Nasolacrimal Duct

Back 9

b/t nostrils
epthelial tube made by fusion of maxillary and medial nasal prominences

Front 10

Maxillae

Back 10

formed from fusion of maxillary and lateral nasal prominences
forms the lateral portion of upper lips and most of cheeks

Front 11

what does the frontonasal process form?

Back 11

bridge of the nose

Front 12

what does the fusion of the medial nasal prominences form?

Back 12

crest, tip, and columella of nose

Front 13

what does the fusion of the lateral nasal prominences form?

Back 13

sides (alae) of nose

Front 14

what does the labial component of the intermaxillary segment form?

Back 14

groove (philtrum) of the upper lip

Front 15

Premaxilla fxns?

Back 15

incisor teeth (front 4) root here

Front 16

Primary Palate features

Back 16

palatine process of premaxilla
posterior to incisors, fuses w/ secondary palate

Front 17

Mandibular Prominences develop into what features?

Back 17

form the lower cheeks and lower lip

Front 18

Palatine Shelves

Back 18

derived from growths of left and right maxillary prominences
form the secondary palate

Front 19

Incisive Foramen

Back 19

small pit b/t secondary and primary palate

Back 26

no
neither do first pharyngeal arch

Front 27

what type of neural crest cells are necessary for facial development?

Back 27

only Hox-negative neural crest cells can develop facial bones
