Question: 1 / 1390

Which statement regarding the secretion of odontoblasts is correct?

Remnants of ameloblasts form primary enamel cuticle

The correct statement is that remnants of ameloblasts form the primary enamel cuticle. Ameloblasts are specialized cells responsible for enamel formation during tooth development. After enamel formation is complete, the ameloblasts are no longer present, but their remnants contribute to the formation of the primary enamel cuticle. This cuticle serves as a protective layer over the enamel and plays a role in the initial stages of tooth emergence.

Understanding the role of ameloblasts in enamel formation is crucial, as this indicates that the enamel cuticle originates from them rather than from odontoblasts. Odontoblasts are responsible for the formation of dentin and are primarily involved in processes related to dentin secretion, pulp health, and sensory perception, but do not contribute to the enamel cuticle formation. This distinction is important in dental anatomy and histology, reinforcing why the statement about ameloblasts is accurate regarding the primary enamel cuticle.
