Hindbrain Neural Crest Migration

A schematic diagram of a chick head at embryonic day two (Hamburger Hamilton Stages), showing pathways of neural crest migration in the chick and mouse embryo and patterns of Hox gene expression in the pharyngeal arches. Hox genes are expressed in neural crest cells, which emigrate predominantly from even-numbered rhombomeres into the pharyngeal (branchial) arches generating skeletal tissues and cranial ganglia.

Note that the first pharyngeal arch is free of Hox expression.

Legend

  • PA - pharyngeal arch
  • Md - mandibular part of pharyngeal arch 1
  • Mx - maxillary part of pharyngeal arch 1
  • OV - otic vesicle
  • r - rhombomere
