Life cycle of an Ameloblast - Amelogenesis

# In the life cycle of an ameloblast, there are cells that contain Tomes' processes. The cells described are in which of following stages?
A. Morphogenic
B. Maturative
C. Organizing
D. Secretory
E. Protective

The correct answer is D. Secretory.

Tomes' process are projections or
extensions of ameloblasts formed as the
ameloblast moves away from the
developing enamel matrix.

The ameloblasts secrete secretory granules
needed for the production enamel matrix
during this phase.

Ameloblasts are actively contributing to the
enamel matrix formation by combining the
secretory granules with the glycoprotein to
lay down enamel during the secretory
phase.

Presence of Tomes' processes is a
histological indicator of the secretory
phase.
