The work carried out with the hypophysis of three calves to demonstrate that a sharp border line does not exist between Adeno- and Neurohypophysis. The result of these experiments show that on the average 57,1% of border line is of connective tissure and the remaining area lacks this type of membrane. In the border area lacking connective tissue, basophil Adeno-Hypophysis cells play an important role in transporting the secretion from Adeno- to Neurohypophysis. The basophil infiltration in the pars posterior are in the form of spread branches which could distinctly be seen; The infiltrating cells are in group or in the form of solid line rather than the isolated form, while the single cells could be noticed around the formers. These cells penetrate only a short distance in Neurohypophysis. The basophil Adenohypophysis cells lose their shape and original charakteristic gradually as they farther infiltrate in, and finally dissolved and considered as a holocrine secretion.
对三头小牛的垂体进行了研究，以证明腺垂体和神经垂体之间不存在明显的边界线。这些实验结果表明，平均57.1%的边界线为结缔组织，其余区域缺乏这种类型的膜。在缺乏结缔组织的边界区域，嗜碱性腺垂体细胞在将分泌物从腺垂体运输到神经垂体中起重要作用。嗜碱性细胞在后叶呈分散分支状浸润，清晰可见；浸润细胞呈团状或实线状，而非孤立形式，而单个细胞可见于前者周围。这些细胞仅在神经垂体中穿透较短距离。嗜碱性腺垂体细胞在进一步浸润时逐渐失去其形状和原有特征，最终溶解并被视为全部分泌。
