Bell Stage Flashcards
when does the bell stage occur?
during 11th and 12th week in utero
the bell stage is characterized by continuation of the ongoing processes of?
proliferation
differentiation
and morphogenesis
what does differentiation lead to?
leads to 4 distinct cells in the enamel organ
these cell types form layers to include?
- IEE
- OEE
- stellate reticulum
- stratum intermedium
describe the OEE
unstratified cuboidal cells
describe the IEE
unstratified columnar cells
what is the purpose of the OEE?
to protect the enamel organ
the IEE will become?
the ameloblasts
the ameloblasts then becomes?
the enamel
b/w the outer and inner enamel epithelium are the TWO inner most layers. Name them
- stellate reticulum
2. stratum intermedium
what does the stellate reticulum and stratum intermedium assist in?
assist in enamel formation
in the bell stage “GAGS” are being generated in the area, very polar! what do they attract?
they are going to attract water in the area
how do the cells respond?
by stretching out and maintaining. they start to look STAR’shaped…..called stellate reticulum
how are they held together?
by desomosomes
why is it important to bring water into the area?
for the creation of Enamel
