Question

Quizplus · Accepted Answer

The neural crest cells migrate from the crests of the neural folds and then join the mesoderm to form mesenchyme.At the cephalic end,the oropharyngeal membrane forms,which consists of only ectoderm externally and endoderm internally,without any intermediate mesoderm.This membrane is the location of the future primitive mouth or stomodeum of the embryo and thus the beginning of the digestive tract.The first branchial arch,also called the first pharyngeal arch and mandibular arch,is the first of six arches that develops in fetal life.The frontonasal process is the midline unpaired embryonic structure that develops into the forehead.
