Explain the process of digestion in the buccal cavity with a note on the arrangement of teeth.

Answers (1)

Ans:

Arrangement of Teeth: In human beings, each tooth is embedded in a socket of the jawbone. This type of attachment is known as the phycodont. Human beings get two sets of teeth in their lifetime, i.e. temporary teeth, and permanent teeth. Milk teeth are temporary and are replaced by permanent teeth. This type of arrangement is diphyodont.
There are four types of teeth in human beings, namely incisors, canines,premolars, and molars. Each half of a jaw contains numbers of each type of teeth. This can be shown by following dental formula: 2123/2123. This shows that there are 2 incisors, 1 canine, 2 premolars, and 3 molars teeth in each half of a jaw. Thus, there are a total of 32 teeth in a human adult.
