Enamel Formation Continues
This tooth is further advanced in its development. The columnar IDE cells producing enamel called ameloblasts. The enamel (A) is the deep purple straining layer forming a "cap" over the reddish dentin layer (B). Enamel is deposited between the ameloblasts and the dentin. Enamel formation does not take place until some dentin has been formed. Note that an ODE (G), stellate reticulum (E) and stratum intermedium can no longer be distinguished in the region over the ameloblasts (at the tip of the developing cusp). The condensation of these layers bring capillary beds close to the ameloblasts which no longer can count on receiving nutrition from the capillaries in the dental papilla because of the intervening layers of dentin and enamel. Identify the structures indicated by the remaining letters.
