Mandible And Tongue Development

Mandible And Tongue Development

“What is mandible and tongue development? A detailed question and answers guide”

Development of mandible
Answer:

In 4th week of IU life, pharyngeal arches are laid down on the lateral and ventral aspects of the foregut.

• Separated by 4 branchial grooves
• The first arch is called the mandibular arch
• The mandibular processes of both sides grow towards each other and fuse in the midline
• Results in the formation of the lower lip and lower jaw.

Meckel’s Cartilage:

• Around the 41st – 45th day of IU life

The first structure to be formed is the bigeminal nerve
↓
Mesenchymal condensation occurs
↓
Activation of neurotrophic factors
↓
Inducbon osteogenesis
↓
Ossification occurs

It starts from the bifurcation of the inferior alveolar nerve in 6th week of IU life
↓
Ossification spreads below and around the nerve
↓
Inbamembranous ossification spreads dorsally and ventrally
↓
Results in the formation of the body and ramus of the mandible
↓
Ossification stops at the site which forms lingula
↓
Remaining Meckel’s carbage which does not undergo ossification forms the following

Condylar process:

In 5th week of IU life

Mesenchymal condensation above the ventral side of the developing mandible
↓
Formation of cartilage at the 10th week
↓
Initiation of ossification in the 14th week
↓
Fusion with mandibular ramus by 4 months

Coronoid process:

The appearance of secondary accessory cartilages at 10-14 weeks of IU life
↓
Incorporation of it into expanding Ramus

Mental Region:

The appearance of Vz small cartilages on either side of the symphysis
↓

Ossification at the 7th month of IU life
