| homology_notes |
A conserved feature of all vertebrate embryos is the presence of a series of bulges on the lateral surface of the head, the pharyngeal arches; it is within these structures that the nerves, muscles and skeletal components of the pharyngeal apparatus are laid down. The pharyngeal arches are separated by endodermal outpocketings, the pharyngeal pouches.[well established][VHOG] |

| taxon_notes |
the dorsal elongation of the second pouch endoderm of all mammals, with the exception of rodents, gives rise to the epithelial lining of palatine tonsils; in rodents, the ventral portion of the second pouch appears to degenerate whereas the remaining part is incorporated into the lateral border of the pharynx; it appears that rodents no longer require tonsils as their function is carried out by the NALT (Nose/Nasal-Associated Lymphoid Tissue) system in the upper respiratory tract. |
