Q

mylohyoid muscle

A

The paired muscles that form the floor of the mouth.
This muscles runs from the mandible to the hyoid bone and forming the floor of the oral cavity of the mouth. It is named after its two attachments near the molar teeth (“mylo” comes from the Greek word for “molar”). These muscles are mesodermal in embryologic origin.

Q

Lingual Frenum: Find in drawing

A

The lingual frenum is a fold of mucous membrane connecting the ventral tongue to the floor of the mouth. In general, lingual frenum serves multiple roles; its main function is to support the tongue and aid in limiting its movement in different directions.

Q

Why is the chronology of Development important?

A

Assess the patient’s DENTAL AGE: Is the patient developing normally?

Important for procedures like: endodontic therapy, and whether or not to extract a tooth.
