"change in identical embryonic cells to become distinct structurally and functionally"
What is Differentiation
100
Where did the 'Nasal pits' originate from?
What is the Nasal placodes

name that palate - "intermaxillary segment from fused medial nasal processes"
What is the Primary Palate
100
Name that stage - "Dental tissues fully mineralize to their mature levels"
What is the Maturation Stage
100
Clinical Ramification - May be confused as calculus deposit on a root Etiological Factors - Displacement of ameloblasts to root surface What is it?
What is an Enamel Pearl
200
"Attainment of adult function and size due to proliferation, differentiation, and morphogenesis"
What is Maturation
200
Where did the intermaxillary segment originate from?
What is - fused medial nasal processes
200
Name that palate - " Fusion of all 3 processes"
What is the Final or Complete palate
200
Name that stage - "Ectoderm lining stomodeum gives rise to oral epithelium and then to dental lamina, adjacent to deeper ectomesenchyme, which is influenced by the neural crest cells. Both tissues are separated by a basement membrane"
What is the Initiation stage
200
Description - Faulty development of enamel from interference involving ameloblasts What is it?
What is Enamel dysplasia
300
"Controlled cellular growth and accumulation of byproducts"
What is Proliferation
300
Where did the Stomodeum originate from?
What is - the ectodermal depression enlarged by the disintegration of the oropharyngeal membrane
300
What structure is demarcated by the merging of the copula of the tongue base, and the anterior swellings of the first branchial arches of the tongue body
What is the sulcus terminalus
300
Name that stage - "Growth of dental lamina into bud that penetrates growing ectomesenchyme"
What is the Bud Stage
300
Description - Union of two adjacent tooth germs What is it?
What is Fusion
400
"Development of specific tissue structure or differing form due to embryonic cell migration and inductive interactions"
What is Morphogenesis
400
Where did the Nasal alae originate from?
What is the frontonasal process lateral to the nasal pits
400
What depression demarcates the beginning of the thyroglossal duct?
What is the foramen cecum
400
Name that stage - "Dental tissues secreted as matrix in successive layers"
What is the Apposition stage
400
Description - Enamel organ invaginates into the dental papilla What is it?
What is "Dens in dente"
500
"Action of one group of cells on another that leads to the establishment of the developmental pathway in the responding tissue"
What is Induction
500
Where did the Frontonasal process originate from?
What is the ectodermal tissue and neural crest cells
500
What fusion completes the palate?
What is the fusion that occurs between the secondary palate and the posterior portion of the primary palate
500
What two stages both involve proliferation, differentiation, and morphogenesis?
What is the Cap Stage, and the Bell Stage
500
Large single-rooted tooth with one pulp cavity exhibits a "twinning" in the crown area (normal number of teeth in the dentition) What is it?
What is Gemination
