Cap Stage Flashcards
what is the third stage of odontogenesis?
Cap Stage
Cap Stage occurs?
b/w the 9th and 10th week in utero
describe the proliferation in the cap stage
tremendous growth (proliferation is going to continue)
not only does proliferation characterize this stage, but various levels of?
differentiation
what are the more specific processes of differentiation in the cap stage?
- cytodifferentiation
- histodifferentiation
- morphogenesis
what is morphogenesis bringing about?
the actual SHAPE of something
what is NEW in the cap stage?
DIFFERENTIATION will START!!!!!
THE CAP STAGE IS KNOWN FOR?
DIFFERENTIATION!!!!!
VERY IMPORTANT
describe the enamel knot formation
Inner most outline determines the future dental shape
and origin is Ectodermal
in the cap stage there is also the formation of?
glycosaminoglycans: (hydrophilic)
glycosaminoglycans is known as?
“GAGS”
what does the “GAGS” do in the cap stage?
they are used to attract water to the developing tooth
where are the “GAGS” location?
desomosome junctions
what is the main thing that the cap stage is known for?
Morphogenesis
the enamel knot in the cap stage will become?
the enamel organ
the enamel organ in the cap stage will become?
the enamel
the inner mass of ectomesenchyme in the cap stage is now considered the?
dental papilla
the dental papilla in the cap stage will produce the future?
dentin and pulp
the remaining ectomesenchyme surrounding the outside of the cap or enamel organ condenses into the?
dental sac
the dental sac is going to contribute to the structures of?
cementum
periodontal ligament (PDL)
alveolar bone
the enamel organ, dental papilla, and dental sac all together is called?
the tooth germ
the enamel organ is what in origin?
ectodermal
the dental papilla and dental sac is what in origin?
ectomesenchyme (mesoderm)
the successive dental lamina adjacent will become?
the permanent tooth bud!
the basement membrane in the cap stage is b/w?
b/w the enamel organ and the dental papilla
the successional dental lamina of the anterior will develop?
lingually
the successional dental lamina of the premolars develop where?
in furcas (furcations) of molars
the successional dental lamina of the molars develop where?
distal from the premolars
