Question

Ectodermal cells that secrete enamel of tooth is.

• A. Osteoblast
• B. Dontoblast
• C. Ameloblast
• D. Odontoblast

Answer 1

The correct option is C

Ameloblast

·Osteoblast: A cell that makes bone. It does so by producing a matrix that then becomes mineralized. Bone mass is maintained by a balance between the activity of osteoblasts that form bone and other cells called osteoclasts that break it down.

·In vertebrates, an odontoblast is a cell of neural crest origin that is part of the outer surface of the dental pulp, and whose biological function is dentinogenesis, which is the formation of dentin, the substance beneath the tooth enamel on the crown and the cementum on the root.

Ameloblasts are cells present only during tooth development that deposit tooth enamel, which is the hard outermost layer of the tooth forming the surface of the crown.
