This section shows the epibranchial placode, lyingjust lateral to the hyoid contact and the primordium of the supra-orbital line,situated dorsal to the epibranchial placode. The histological characters whichserve to distinguish the ectodermal thickening and the epibranchial placode fromthe sensory line primordium are shown in this section.
