Coincident with this transformation the mesenchyme of the hyoid and mandibular bars undergoes proliferation and becomes condensed to form the primordium of the auricle. Foci of more active proliferation show on the surface as branchial hillocks. Specimens are from the Carnegie Collection.

Plate 2. Drawings of human embryos, showing the region of the first branchial cleft and its transformation into a fossa angularis

Coincident with this transformation the mesenchyme of the hyoid and mandibular bars undergoes proliferation and becomes condensed to form the primordium of the auricle. Foci of more active proliferation show on the surface as branchial hillocks. Specimens are from the Carnegie Collection.
