Question: 1 / 1180

What does the internal enamel epithelium become?

Ameloblasts

The correct answer is A. Ameloblasts.

The internal enamel epithelium, also known as the inner enamel epithelium, is a layer of cells in the enamel organ of a developing tooth. These cells differentiate into ameloblasts, which are responsible for the formation of enamel, the hard outer covering of teeth. Ameloblasts play a crucial role in enamel formation by secreting enamel matrix proteins and regulating the mineralization process.

Options B, C, and D are incorrect:

B. Odontoblasts are cells located in the dental pulp and are responsible for the formation of dentin, not the internal enamel epithelium.

C. Cementoblasts are responsible for forming cementum, which covers the roots of teeth, and are not derived from the internal enamel epithelium.

D. Dentin is a hard tissue that makes up the bulk of the tooth structure and is formed by odontoblasts, not the internal enamel epithelium.
