Abstract:
Gnathostomata improved the brachial cartilages of Agnahta into jaws. At the same time, such a jaw formation resulted not only in the development of eye, nose, and ear for searching foods but also in the development of brain which regulates the functions of these sense organs and mastication muscles. In this paper, we described about the muscles, mouth, tongue, and jaw which participate in mastication from a view point of morphology and molecular biology.

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
