| Janvier agrees that gills, and perhaps the external branchial skeleton, are primitive to the chordates. |
| Could it be that the parathyroid is also derived from a branchial arch, and is therefore homologous with the gills of fish? |
| Six cases of false positive patients were reported: 2 acinic cells carcinomas, 2 pleomorphic adenomas, 1 dermoïd cyst, 1 branchial cyst. |
| In fish, the branchial apparatus forms a system of gills for exchanging oxygen and carbon dioxide between the blood and the water. |
| Due to the reduction of the hyoid and branchial arches, no other means than the suction flow seems to be available for this function. |
| Numerous small pustules occur on surface of branchial regions. |
