What causes cleft lip embryology?

Cleft lip results from a failed merging of the maxillary and medial nasal elevations on one or both sides due to the inadequate migration of neural crest cells. Cleft palate results from the failure of the lateral palatine processes to meet and fuse with each other.

How palate is formed?

The palate is formed by the palatal processes of the maxilla. The central part of the lip (prolabium) and the premaxilla arise from the medial nasal prominences of the frontonasal process and the lateral alveolar segments from the lateral processes of the maxilla.

What are palatine shelves?

a medially directed outgrowth of the embryonic maxilla; when fused with its opposite number it forms the secondary palate. Synonym(s): lateral palatal shelf, palatal shelves.

How long does it take for palatal shelves to fuse?

week 9
Fusion between the two palatal shelves occurs during week 9 of embryonic development. In this time, the elevated palatal shelves join together to form one continuous structure, with the medial edge epithelium (the shelf surfaces which are closest to each other) disappearing.

How can I prevent my baby from having a cleft lip?

What can you do to help prevent cleft lip and cleft palate in your baby?

  1. Take folic acid.
  2. Don’t smoke or drink alcohol.
  3. Get a preconception checkup.
  4. Get to a healthy weight before pregnancy and talk to your provider about gaining a healthy amount of weight during pregnancy.

What is the function of the palate?

The soft palate and hard palate form the roof of the mouth. The soft palate is at the back of the roof, and the hard palate is the bony part of the roof closer to the teeth. The main functions of the soft palate are to aid speech, swallowing, and breathing.

What are the three stages of palate formation?

The palate is then completed later during the twelfth week, within the fetal period. Thus, the palate is developed in three consecutive stages: formation of the primary palate, formation of the secondary palate, and completion of the final palate.
