ex1 molecular tooth development

Question 1

T/F neural crest cells > ectomesenchymal cells ? odontoblasts, cementoblasts, osteoblasts

Answer 1

True. Neural crest cells migrate and differnetiate into ectomesenchymal cells that further differneciate into many -blasts tyes of cells inlcuding tooth relelvant osteoblasts, odontoblasts, and cementoblasts

Question 2

T/F neural crest cells, mostly from the hindbrain, travel to well-defined migratory streams to the branchial arches from where they are involved with craniofacial developemnt

Answer 2

True. the neural crest cells NCC travel from the hindbrain to brnachial arches (facial dvelopment from brnachial arch 1)
