Using the technique of linar marking on the embryonic thyroid of chicken, it was proven that the thyroid anlage after its evagination from the primitive pharynx, does not undergo any caudal migration. Its topogenesis is influenced by two main mechanisms. First, the relative craniocaudal displacement follows from the cranially oriented growth of the neck and second, the enlarging oesophagus presses the trachea ventrally against the thyroid anlage promoting its division and separation of both lobes.
利用对鸡胚甲状腺进行线性标记的技术，已证实甲状腺原基从原始咽外翻后，不会发生任何尾侧迁移。其拓扑发生受两种主要机制影响。首先，相对的头尾位移源于颈部向头侧的生长；其次，不断增大的食管将气管腹侧压向甲状腺原基，促使其分裂并形成两叶。
