In a series of 21 human fetal thyroid glands examined histologically in serial sections, seven ultimobranchial body cysts were found. The position of these cysts correlated well with the distribution of calcitonin-containing cells found by previous investigators in the adult thyroid gland. Ultimobranchial body cysts found external to the thyroid lobes may offer a developmental explanation for the paucity of calcitonin found in some adult thyroid glands. The close developmental relationship between the parathyroid gland and the ultimobranchial body could explain the presence of calcitonin found in these glands in some adults.
在对21个经连续切片进行组织学检查的人类胎儿甲状腺进行的一系列研究中，发现了7个鳃后体囊肿。这些囊肿的位置与先前研究人员在成人甲状腺中发现的含降钙素细胞的分布密切相关。在甲状腺叶外部发现的鳃后体囊肿可能为某些成人甲状腺中降钙素缺乏提供一个发育学解释。甲状旁腺与鳃后体之间密切的发育关系可以解释在一些成年人的这些腺体中发现降钙素的原因。
