external definition

Anatomical structure which originates as several paired thickenings on the dorsal side of the pharyngeal pouches and secretes thymosin.[AAO]

homology notes

A thymus develops in all vertebrates from the endodermal epithelium of certain pharyngeal pouches and from the adjacent ectodermal epithelium. In fishes, all the pouches, or the first four, contribute to thymus formation, but in tetrapods, the number is more restricted. In mammals, only the third and fourth are involved, and the contribution of the third is by far the greater.[well established][VHOG]
