Description By 55 hpf, the ceratohyal (ch) consists of a condensation of chondrogenic cells in several layers that is difficult to distinguish along its dorso-posterior aspect from the ventral portion of the articulating interhyal (ih). Additionally, the articulation with the basihyal (bh) dorsally and the contralateral ceratohyal medially at the anterior midline is indistinct. Alcian blue staining of matrix is observed in these developing cartilages at this stage.
