Moreover the epithelial covering and associated basement membrane of the palatal shelf exhibit differential traction, which serve to constrain and direct the swelling osmotic force.
Palatal shelf elevation and fusion depends on fetal neuromuscular activity, growth of the cranial base and mandible, production of extracellular matrix and contractile elements in the palatal shelves, shelf adhesion, PCD of the midline epithelial seam and fusion of the ectomesenchyme between one shelf and another.
5 induce a cleft palate through inhibition of palatal shelf development.
The above results did not exclude the possibility that endogenous, atRA-dependent events are required to allow TCDD-induced inhibition of palatal shelf development.
The study focuses on the pathways hypothesized to be involved in the disappearance of the palatal shelf medial edge epithelium during embryonic development.

7 % eye length; one or two nonconical postrictal tubercles posteroventral to tympanic annulus; choanae round, not concealed by palatal shelf of maxillary arch; vomerine odontophores median and posterior to choanae, separated medially by distance 1 1/2 times width of an odontophore, each about size of a choanae, each bearing 1-3 teeth (mode 3) arranged in transverse row; odontophores slanted in smaller specimens, subtriangular in adults; tongue longer than wide, not notched posteriorly, posterior 1/4 not adherent to floor of mouth; vocal slits posterolateral to tongue, long; vocal sac subgular, median.
