Final answer:
The enamel organ develops into the enamel, which is the protective outer layer of the tooth. It provides protection for the dentin and pulp cavity, but can be eroded by acids from bacteria in the mouth, leading to tooth decay. The formation of enamel is part of organogenesis during embryonic development.
Step-by-step explanation:
The enamel organ becomes the enamel covering of the dentin of the crown of a tooth. The enamel is a vital part of tooth structure, providing a hard protective layer over the dentin and guarding the inner pulp cavity. The tooth enamel, even though it protects the underlying dentin, can be vulnerable to tooth decay, also known as dental caries, which occurs when bacteria in the mouth produce acids that degrade the enamel.
Throughout development, tissues and organs are formed via a process known as organogenesis. During gastrulation, different germ layers are established and eventually give rise to various structures. It is during organogenesis that the enamel organ develops into the tooth enamel. The accessory digestive organs, such as the teeth, play a role in mechanical digestion within the mouth, while organs like the salivary glands, liver, and gallbladder contribute to chemical digestion.
